[@nicknamednickify]

I've watched your channel for years and one thing I've really appreciated is your knowledge of sealing and insulating. As an electrician, having installed those Arlington in-boxes I had to wonder why anyone would want a great big hole like that in their exterior wall cavity, because you just know the insulation is gone, being taken up instead by this giant hollow plastic box. It's a huge energy leak. Thanks for showing your solution!

[@brandonmoore1950]

You could go through the expense of having all 20A circuits, or you could tell your electricians to put the lighting and receptacles on separate circuits. Have lighting on 15A and receptacles on 20A. Just my opinion but you’re the boss😂

[@ryanroberts1104]

But then he can't brag everything is on 12 gauge!

[@frankyb702]

you can but the extra labor and planning might not be worth simply keeping it all 20

[@ryanroberts1104]

@@frankyb702 It's actually more labor to work with 12ga, as numerous electricians have pointed out. Since lighting and outlet circuits should be separate, regardless of wire gauge, it's not hard to use 2 different flavors. You still have to put other things on wire bigger than 12ga, so it's not like the whole house is done that way anyway. And if you use 14 for the lights it is easier to identify in the future - white romex = lights, yellow romex = outlets. Kind of like using the blue and red pex...few people just use white for both. Even if wire is free it doesn't make any sense to use 12 for lights...also, even if you have 12ga for your lights, it's better to put lighting circuits on a 15A breaker too - again, easier to identify. I totally agree with outlet circuits, 12ga/20A for sure, although still very unlikely to ever use that capacity. (Especially for an energy nazi like Matt) More importantly if you hire an electrician tell him to do it right, don't tell him what kind of wire to use. That's his job, why did you hire an electrician? I can just imagine the face palm when the clueless customer starts dictating wire size...

[@fredflickinger643]

With the introduction of many low voltage LED lighting fixtures, it makes so much more sense to separate the lighting and receptacle circuits. Making it even easier for automated control later especially if you make your lighting runs to a separate box and your breaker feeds to that box. Join them with wire nuts for now and later you could insert full automation control when you are ready. This and not having to rely on unreliable wireless control of your lights.

For who might be interested: In the Netherlands most new homes get 3 phase, 220V/25amp (used to be 220V,16Amp, but solar and electric cars made 3phase become the standard). With a mains panel in an indoor door closet that's standardized for gas, water, electricity and data/telecom input and meters. Positioned within 3m (~3ft) of the front door. All wiring goes through pvc 3/8" (sometimes 1/2") piping. Every group has a 16Amp breaker per group. Separate groups are required for bathrooms, kitchens build in appliances and mechanical. Most rooms have one group going to a ceiling box (3"×3"). From that box all other points in the room are fed. And the box itself is used for the lamp. Data wiring all goes from the "meterkast" (the door closet with the meters) to the points around the house and also through 3/8" pvc piping.

I understand people's hesitation with hub required home automation but many of those standards are purpose built for low bandwidth distributed devices. I ended up going almost entirely z-wave mesh network with a hubitat hub for my own home and I'm glad I did. There are tons of z-wave devices by different brands offering different feature sets if you every find yourself wanting something specific and the frequency range it uses doesn't conflict with wifi.

[@raymondt817]

This comment should get more upvotes. A hub makes things easier because you can combine other devices together. Otherwise you'll probably end up with 4 or 5 different apps on your smartphone to control different devices from different brands. With a hub, you can have your brand x motion sensor turn on your brand y lights. And the switches are more affordable because you are not beholden to a specific brand.

[@paulhartman3118]

Hubitat also integrates well with Lutron Caseta. Just get the Caseta Pro controller to allow for integration.

[@sailorloki]

@@raymondt817 Totally agree Ray. z-wave is the way to go if you don't want to be opening 5-8 different apps to control everything. I've got everything tied to a qolsys IQ 2 plus panel. And tied to alarm.com for cellular connectivity. It's awesome to have EVERYTHING in a single app, from my garage doors, door locks, lights, Hvac, sprinkler system, motorized blinds, cameras, water sensors, etc etc. I love all of Matt's Build stuff, but this is not what I would consider a "smart" home lights at all.

[@lavigha]

Yep, totally agree! Will be interesting to see if he has any issues with the Bluetooth.

[@spencjon4822]

You can also use something like home assistant (or other ‘open source’ home automation software) to manage all the automations in one place. You then are not stuck to only z-wave or zigbee or whatever devices. I even have both z-wave and Philips hue devices that run on the same actions. More important though is your sentiment that you should use hub-based tech. Bluetooth is fickle. As a software dev, I will not rely on Bluetooth lights/whatever as they will have more problems in the long run. Not to mention that these other protocols (like z-wave) are designed for exactly these purposes.

You will appreciate this Matt. My first home I built back in 1978 I used all 12-2 WG and a 400 Amp commercial panel that was about 4 foot high. The home was all electric.

Matt, I know you mentioned the Big L when it came to smart lighting as being expensive. You are correct when it comes to their Radio RA and HomeQS but their Caseta system is a game-changer. Advantages: No need for special wiring. Caseta switches are a direct replacement for traditional switches. They work with ALL traditional light fixtures so there's no need to be locked into one brand of lighting. They make 3 and 4 way switching a thing of the past; 3 pole switches are replaced by a single-pole smart switch and Pico remotes are used anywhere you want secondary switches. The remotes look like switches and can be mount on the walls as such or sit on a table in a pedestal. The system is just as programable as any other out there, but it steals from its bigger brothers, so you get more functionality for less money. Note I am in no way affiliated with L. I just did a lot of research before I did my house and Caseta was by far the best solution. That said my daughter is a designer for a local company and they use RA and QS. Next comment: If you are truly going to build a smart home, do not forget about your computer network. Almost all smart devices like TVs can be hardwire connected. RUN CAT6(a) to every room. DO NOT depend on WiFi especially when it comes to streaming media. Cable is cheap when the walls are open. As an IT professional, I tell all my clients that there is no reason why a (smart) home shouldn’t benefit from a business-class network. And with so many professionals working from home post-COVID, now more than ever is the time to start building even modest homes with wired networks. WiFi will never replace the quality of a good, wired network. Lastly, my cardinal rule of building a Smart Home is for it to be smart enough to allow people to interact with it in the traditional way. Love your videos. Would love to talk more about home-based networking and smart home technology.

Hey Matt, this gave me a lot of subtle details to make a build more enjoyable.

Ive been waiting! Thanks Matt I always look forward to Tuesday and Friday

[@gonzalezfd]

Thanks for the video Matt. I am a DIY, remodeling my entire home and since i'm saving $ on contractor labor I have a bigger budget for materials so I started installing 12 gauge wire for everything but that was a mistake. From my experience, it's nice having 12-2 because I can extend circuits to multiple receptacles without worrying about amp capacity but the downside is with installing the lighting (especially halo recessed lights). It is much easier wiring lighting fixtures with 14 gauge than it is with 12 gauge and NEC doesn't allow for downsizing if you start with 12 gauge and switch to 14 gauge in a branch. Anyways, i've learned a lot from your videos so thank you.

[@efdh2]

The Halo line is only 5% dimming. He is going to really regret that. People don’t understand how important 1% dimming really is. I personally feel that Lutron has significantly better lighting control systems. Also, If you’re going to go to the extent of having smart lighting, and home control, you really should have an IALD certified lighting designer do your lighting plan and fixture specifications. Unlike interior designers, an IALD lighting designer DOES NOT make money of off fixtures or get kickbacks from manufacturers. A good lighting designer will help you avoid a lot of lighting pitfalls, and also keep you in budget. I can’t even begin to tell you how many bad lighting layouts I’ve seen done by architects… Lighting has become a true specialty, and it’s well worth the investment to make sure you’ve got the right person looking after it. I am not a lighting designer, but I would never build my custom home without having one on board from day one of design. Worth every penny.

[@Cstegg]

Bluetooth is also an awful option for large amounts of lighting as well. He should have gone with Zigbee, or Zwave devices. Those are also not vendor specific protocols and can be controlled without proprietary apps. That app he has might not be supported in a few years and he is also stuck in the ecosystem of those lights. With Zigbee/Zwave lights you can mix and match manufactures to work together. They also form a mesh network to keep devices from dropping off which I guarantee he will be having issues with bluetooth. Just speaking from firsthand experience. I imagine those were sponsored products anyways.

[@kg4lod]

@@Cstegg "Bluetooth" as used in modern lighting products is actually the "LE" version which supports mesh networking. ZigBee often uses the same 2.4GHz as BT, with the same penetration problems. Zwave is a closed proprietary protocol. BT LE is actually a very reasonable choice and improves every year with better vendor adoption. I worked on the original ZigBee specification and even I say it's not significantly better than BT LE in the generic smart home use case. The 2 protocols can be remarkably similar when configured so.

[@cdavidmercier]

I think the all 12 awg wire size issue has been fully discussed. It is personal preference. When building my house, after I saw the price for all 12 awg I asked for dedicated circuits to heavy load areas such as entertainment and office desk. Kitchen, bath, and laundry already require 12 awg. I ran 12 awg to outdoor outlets to limit voltage drop on extension cords for DIY projects. As far as aluminum, the problems are myths. I surveyed wire and connector manufacturers on failure rates. No difference between aluminum and copper. Always make sure connector is listed for the wire used. Past problems have been with connectors not listed for use with aluminum. I also have found, rough electrical is very regional as can be seen in the comments. I installed two 200 amp panels for future expansion as I had several unfinished rooms. My brother, the contractor, only advice was to run empty conduit from panel (in basement) to attic for future expansion. That extra conduit is full today! The extra space for breakers has also been needed. The commenter’s mention of Cat 6 wiring is perfect. I installed Cat 5 20 years ago to future proof. Today I am using only one coax for incoming internet and the Cat 5 phone wiring that was used for phone has been converted to an Ethernet network. BTH, the only issue I have had is when doing work with switches, the backstabbed 14 awg causes the switch back to crack and have a loose connection. This has happened in three switches so far. Also, for frequently used outlets (vacuum cleaner) buy a commercial grade outlet.

[@opinionatedman]

As an electrician some of this is overkill and some makes sense. For one 12/2 throughout the house is a waste, but the middle ground that has logic is doing the receptacles in 12. In a brand new home no one should need to plug in portable heaters or window AC units, which are 2 of the biggest culprits I find people overload their circuits with. Older home's didn't require a 20A bath circuit either. I've seen hair dryers with a wattage label of 1875W, which is more than a whole 15A circuit. Again that's an old home problem in an area already addressed by code. A vacuum can draw around 12 amps but it is usually a temporary load. Excluding kitchen/dining/bath areas that already require 20A circuits, most people will never utilize a fraction of any of those 20A circuits. One cost saving route would be to put more receptacles on a circuit. With most lighting going the LED route that's even less load in the system. Having breakers on the exterior of the house I just hate the idea of it. Main outside if you must; 2020 code when adopted will mandated an exterior shutoff. The whole copper/AL issue has long been settled. Those AL wires will not loosen on those lugs if installed properly, neither will the copper. If the customer wants copper and they got the cash I'm happy to install it, but overall I feel the extra money spent on copper feeders and 12/2 on lighting could have been put to better use elsewhere.

[@nunyabidness3075]

It would have helped in my garage where I run a tool and a shop vac and trip the breaker. Of course, not putting all the outlets on a single breaker would have been nice, but you know those electricians. 😂🤣😂

[@akyak333]

actually aluminum has a different compression than copper - virturally all aluminum wire will have to be re-torqued after a year. and it's better to have the extra capacity since it's alway about accomodating potential.

My dad happens to be a pro electrician, I used to work with him growing up. 14 is all you need for vast majority of homes if you are building to code and doing your load calculations correctly. Kitchen gets 12/2 or 14/3 due to powerful appliances used there. Future is about using less power, not more, LED lights being a great example. Honestly the only time I've seen or heard of popped 15a breakers was when someone got a cheap reno with no inspection electrical or in really old homes.

[@bf2wesley]

@Matt, have you considered the security aspects of your electrical and smart home setup? For example, your 220 box for mechanicals is outside and easily accessible to potential bad actors. Also, bluetooth is just about the least secure means of wireless communication, it's super easy to exploit. I.e., someone sitting outside you house could shut off all your electrical and/or change your lighting programming. On a tangentially related note, have you considered physical security in the design of your house? I think a video on that would be useful for many of your viewers, who might know to air seal the slab to framing but not know the difference between a truly high security lock system and a Kwikset from their local big box store.

[@InterstateLoveSong]

2020 NEC requires an emergency disconnect outside. At the very least his main breaker would still have to be outside per current code.

[@bf2wesley]

@@InterstateLoveSong that's a good point I wasn't aware of, thank you for bringing it up. I thoroughly dislike that addition to code for security reasons, although I understand where it's coming from. That being said, code is what it is. So, my first thought is that I'd double down on the physical security of the panel box itself: I'd probably have a custom one fabricated or at least have the door of an off the shelf panel box modified to take a legit lock. Then I'd use a high security smart lock to secure the door, so if I was expecting maintenance I could authorize temporary access. The security vulnerability is just too significant not to try and mitigate somehow

Main panel on outside is great for sub panels for pools, buildings, generators, etc. You should have just run a 200a subpanel interior for everything. So one penetration. 2. The lugs on the panels are aluminum, so technically you just mixed metals. They have designed all the new boxes to work fine with aluminum. 3. Most circuits these days require 20a anyway, but for the bedrooms, I prefer more circuits than higher gauge wire. 4. Smart switches.. so obviously it's sponsored, but no custom home should be putting Bluetooth switches in. Control4, lutron, zwave, zigbee are much more standardized and reliable.

Long term, hackers can find vulnerabilities, and operating systems can change, forcing you to upgrade. There is a lot of technology that is beyond the control of the people building it. There is a lot of programming that is beyond the ability of the computer programer to control. Today, in new construction it still makes sense to wire everything the old fashioned way so that the technology could be removed and replaced with old fashioned simple switches.There are places where is makes cost effective sense to use this technology.

12-2 is overkill Matt. If you are worried about heavy loads in individual rooms, just wire the receptacles seperately in 12-2. 12-2 in all circuits is a total waste of money. All houses are usually re-wired well before 150 years. Wire and insulation changes significantly every few years. LED's are used extensively in modern homes, which reduce the lighting load significantly. 14-2 is all that is needed for lighting circuits. Great video.

[@comingtofull-ageinchrist6736]

as an electrician in Oklahoma, I can say that electricians wiring new homes, that I have seen, are using 12/2 for home runs and jumpers for duplex receptacles and to heat up a switch. Some of your branch circuits like laundry and small appliance branch circuits, they are required to be 20 amp circuits; even on switch legs, which you can get away with a 14/2 and still be on a 20 amp branch circuit, all electricians I know are using 12/2 and 12/3 for 3 way and 4 way switches. The NEC code actually requires 20 amp branch circuits on some of the branch circuits in the home that are likely to have motor loads on them, like small appliance BC and Laundry. I have seen some electricians in Texas do some remodels and use 14/2 for switch legs, but I think every one is using 12/2 and doing 20 amp branch circuits for homes. I don't know if that is to accommodate space heaters that many people use during the winter time, but it certainly is wise to run 20 amp branch circuits for homes! I'm just speaking for the experience I have had, but I have certainly seen some of the storm relief mobile homes made by FEMA for storm relief shelters use 14/2 as early as 1992. Great advice!

I'll just affirm what some others have already said and add that the idea that 14ga is "worse" is fundamentally wrong. It just has a different use case. An old joke amongst electricians is that you can always tell when a homeowner did the wiring because everything is done in 12ga since they think "bigger is better". In some instances it may make sense to do a circuit in 12ga even when not required by code, but in others it may make no sense at all, and cause issues with box fill etc. Consult your electrician for your specific scenario and I think you'll find a majority dont agree with this concept.

I would argue that wiring your outlets as 20 amp circuits could actually be considered more dangerous, yes you can potentially power more devices on a single circuit, but what happens when one of those devices ends up with a short inside of it, that 20 amp circuit will now allow even more current to flow through that device which is typically rated to be plugged into a 15 amp circuit.

Aluminum wire does not need noalox, it's not required by any major panel maker or any large manufacturer of wire such as Southwire. It does however need to be properly torqued to the panel manufacturers spec. The alloy of aluminum in use today is very different from the one that was first used in homes that had issues.

I find Caseta and Raw 2 much better option. The 12-2 VS 14-2 has been a open Debate 4 years but I also charge more in labor. You also run into wire fill issues using 12 wire. I wouldn’t waste the money on it for lighting that’s for sure. The Aluminum is a much better conductor for feeder branches and worth the price savings. But in all a good Video always enjoy watching.

So weird to see the main panel outdoors. Almost as weird as all the external water heaters down there. I'll never get used to seeing that stuff.

[@phylismaddox4880]

I remember staring at the first indoor main panel I ever saw. ;D

[@ElAnvaBar]

@@phylismaddox4880 In the Netherlands all homes have indoor panels. But code requires them all to be 3m (~9ft) from the front door. They go to a shallow build-in cabinet/door closet that is standardized for gas, water, electrical and data/telecom, input and meters.

[@InterstateLoveSong]

You will see it more and more since the 2020 NEC requires an emergency disconnect outside. So new homes and existing ones getting service upgrades will at least have a small panel with the main and a circuit to the sub panel or the entire panel outside. This was common when I lived in Colorado. Lived in a few houses where the entire panel was out next to the meter.

The panel outdoors thing is more a code thing than a regional thing. The water heater thing is weird for sure thoughz

Surface flush LED extrusions that are 5/8" deep are a must.

Does a bear shit in the woods?

Why is that ?

Plenty of Builders in that camp too.

@@buildshow good reply Mr. Risinger, I am sure they have the opposite of hate, they bill for it and am sure it always works in their favour. If they do what you ask, and you are happy I am sure they are happy as well. Clear expectations, directions and QC and everyone is happy.

@@shootmovecommunicate3322 i think cause typically bears live in some kind of wooded area unless it’s polar bears then it’s like Disney on ice 😂 sorry it’s late and I’m being silly

I like the detail of the one hole per wire to easily seal it up afterwards. That will definitely avoid condensation. Well done.

What is the benefit of a separate 110 panel? Wouldn’t one 110/220 inside be better?

[@nirpy]

-Panel capacity (no expensive tandem split breakers needed) -Generator panel for 120v circuits -Ease of resetting breakers from inside the house (including afci/gfci trips) -Shorter homeruns -Conditioned space better for longevity on smart breakers and probably the afci $$ too. -Conditioned panels also trip less on hot summer days and don't freeze in the closed on position mid winter

sure, but this is Texas. we do power our unique 2-stepping & stumbling way ;-)

[@guytech7310]

There really aren't 120V panels. Most subpanels are 240vac that are split phase. 220V circuit is L1-N-L2. Each Lx is 120v when tied to neural ie L1-N = 120V, L2-n = 120V & L1-L2 is 240V Generally subpanels are useful to reduce wiring costs or if or adding rooms to an existing house & don't have an easy way to run all of cabling back to the main breaker box. Sub-panels are also used for critical loads for a generator\UPS\Solar setup which the power source (GenSet\UPS\Solar-Inverter) cannot handle all of the loads. You put your critical loads into the subpanel (ie frig\freezer\lighting) to segrate from devices like the AC, electric Dryer, electric stove, etc.

[@kc9scott]

If Matt later wanted to put in a 240V breaker into his "120V" panel, he'd be able to do it, the same as any other panel. He just chose to put only 120V circuits in it.

Good video. I hope you make a video where you put up external wired cameras also. I plan on doing an ICF based house with a dozen external cameras and probably four of those floodlight systems maybe six of the ones you showed here
