There has been a few comments about if the customer was concerned about his archive, he wouldn't be storing it in a wooden building, these building are treated with a fire retardant chemical to comply with uk building regs , any wooden building in the UK that is design to accommodate people must be treated we a fire retardant chemicals . So when you do any electrical you must bare that in mind and treat any bare surfaces you create

What bit holder did you use on this video ?

[@artisanelectrics]

Armeg extension bit

[@RealAshleyBailey]

The reason its called cement is due to its dynamic properties, the way a glue works is the glue becomes the bonding material where its sticks 2 materials together, however a cement bonds the materials together by fusing the plastic together like you would with welding metal together

[@RWBHere]

27:00I s cement, not glue. Cements react with surfaces, so the two parts become one. (Plastics are dissolved and essentially weld together.) Glues only adhere to surfaces and hold the two parts together.

[@blower1]

Yes! - this is where i'd store all my precious, irreplaceable things that are delicate and sensitive to moisture.....in a single skin, uninsulated flammable wooden structure, with glass windows so everyone can see what's inside and can easily break in if they need to. But just in case the one in a million chance of a normal consumer unit going up in flames from the very small load that will be put on it....i'll spend a small fortune on some AFDD's!.....i'm glad i got my priorities straight :)

[@dsesuk]

I'd recommend an RN+R2 test as well as R1+R2 for AFDDs as a loose connection on the neutral will trip the device just as easily as a loose connection on the line. If both numbers check out the same, then that proves no loose connections... as far as such things can be proven, as one result validates the other. The disco lights on these Wylex models will flash away until you push the test button again at which point the indicator will reset back to red; the device will only trip from the test button if pushed while the indicator is red. Considering these things are supposedly to be mandated a year from now, few manufacturers seem to have products ready to market and pricing remains prohibitive. We'll watch this space I guess.

[@cbcdesign001]

To me these things are just a very expensive solution to a problem that exists considerably more frequently in the minds of the people that stand to profit from them than it does in the real world.

[@artisanelectrics]

Thanks that’s great info David! I was hoping they would stop flashing by themselves and I didn’t even realise they had a test button LOL

[@dsesuk]

@@artisanelectrics Yeah, it's not terribly obvious on these models, but it's below the toggle (it's the flashing indicator itself) and it's one of those that as you press it, it causes the toggle to whip down onto your nail!

[@TheChipmunk2008]

@@dsesuk Ah,. designed by ... the same people who make John Lewis light fittings? I share your interest in waiting to see what is going to happen if/when they become mandatory, re pricing

[@mathman0101]

Fully concur with David here on the Rn+R2 testing it’s a nice little check. Though if neutral is not properly connected I doubt you would be able to get the AFDD to move from the tripped position in the first place. It’s also what I do in the US with regards to testing but we also have testers that can help. There is a lot of research going into this to continually refine them. If I was in the UK and the wiring in my home was more than 40years old AFDDs could really add to safety if you were not interested in rewiring. At more than 40 years old wiring I may be really thinking about rewiring it anyway if testing has shown deterioration over time. We have the additional issue here in the USA that we often fit combination RCD/AFDDs downstream in the radial/branch circuits as well - a kind of belt and braces approach. So there will be tripping at both the consumer unit and the downstream device. For us the prices have come down significantly so the cost is not really an issue if you have a large house with a lot of varying loads and assets tied up in it then AFDDs could further add to safety. Insurers should be providing discounts for this on the home insurance which would increase their adoption. Latest generation of panels here in the USA we have click-on breakers including combination GFCI/AFCI and WiFi connected to allow remote monitoring circuit by circuit and all connections on the large busbar itself getting rid of those horrible pigtails - leading to cleaner and faster install with more space left over to allow improved air circulation improving heat management.

[@roymorton8142]

Just a small tip, when I’m setting up my cable drums on the stand I alternate each cable reel, ie I roll one off the top, next one from the bottom, next one from the top and so on, this causes some friction between each reel and keeps the cables from tangling.

[@mikeselectricstuff]

Alternative to a fishtape - tie an M8 nut to a length of thin string, and use a strong magnet from outside the conduit to pull it along.

[@havoctrousers]

That's a good one. I've seen people tape a freezer bag over the end of the cable and then use the hoover to suck it through! :)

[@GordonjSmith1]

From a consumer perspective, any devices that protect a circuit (and those things associated with it) are very worthwhile. I would also add that any devices that help an electrician locate a problem in the shortest possible 'on site' time, also save the client money, and the electrician 'grief'. Recently had a problem in our house in Denmark, and because we had a radial wiring circuit, RCDs, and a small number of devices per circuit, he found the problem in under 5 minutes, fixed it in an hour, and got a contract to create a new installation for our garden (yes another radial circuit from the consumer board, properly protected). I am most impressed when professionals 'build in' future 'value' to their work.

[@roydowling2542]

I always put the fish tape through the conduit first. Tie onto the end you pushed through and pull the fish tape back. That way you don't need the whole fish tape and it's less likely to tangle itself up.

[@TheChipmunk2008]

When I was trained, (this might be local to me) a fish tape was the metal one... the thing Jordan had was called a drawtape. Mouse is indeed colloquial

[@cjaycdr]

Remember the burnt-down board replacement you did a while a go? That fire/arcing most likely started at the mains switch, if I remember well (according to Clive's diagnostics..). An AFDD on the downstream circuits does little to protect from arcing on the mains switch... So in this case, by design, it probably makes more sense to put an AFDD circuit breaker in the uplink so it protects the SWA and mains switch as well. That way you achieve full AFDD protection for the complete electrical circuit running into the shed/chalet. Plus it might be an answer to your concerns about any excess mechanical stress on the SWA crossing the small pavement directly outside the shed. Much appreciate the amount of thought you're putting into addressing customer concerns using modern technology. They set a good bar for both newcomers as well as seniors in the trade.

[@normanboyes4983]

As you are open to suggestions and discovered that adjustable spanners do not make a mess of SWA glands, you could go one better and just use the right size spanners.😉 Btw - after such a beautiful trenching job, to bring the end of the supply cable over the top of the slab beside the door was a bit of a let down.

[@UserName-yk7om]

Nice work by you and your team :) Maybe a good idea to drill a pilot hole from the inside in the future projects and then drill from both sides through the wall & let the holes meet in the middle, with the Bosch-bit, to avoid blow-out on either of the sides of the wall 😉

Knipex "pliers wrench" (86 series) are such an improvement over adjustable spanners. Get a couple of different sizes and see how you get on.

[@BjornV78]

I know this is an older video, but at 10:12 why not bring the armored cable up around the corner behind the wood, to just below the fuse box, then drill a hole in the wooden side wall so that the cable at a 90° angle enters the bottom of the fuse box? This has several advantages : 1) The cable is not visible from the outside when you stand in front of the garden shed (or you have to look behind the wooden corner). 2) On the inside of the shed, the armored cable is much less visible 3) You don't have to drill through 2 shelves 4) When the door swings fully open, the bottom can't pinch against the armored cable.

[@russrockino-rr0864]

We have Arc-fault plug in testers in the US, that plug in to receptacles(sockets). They have push buttons to test the AFCI's. They are similar to our plug in GFCI Testers. Ideal Electric makes one. I am sure Klein probably makes one also. Great Video, Jordan. Thanks, Russ from Oregon.

[@jsb7546]

Wow no shit. That's cool to know I have the GFCI tester from Klein now I'm gonna have to get the afcj tester they have. Didn't even know that's dope tbh. Greetings from the eastern side of Oregon my self.

[@imark7777777]

Would love to know how it's actually testing that. As far as I'm aware of that's the only tester. and it's not required by code to Test right? After the trouble John Wards and David savory went through to test AFDDs. I can't imagine our testers are doing much more than injecting some sort of trigger pulse. Which is slightly warring seeing how the whole standard was written into the code via one company wanting to push it's product. It just seems like a expensive way to maybe detect faulty workmanship and caused false triggering.

[@dannyboisparky]

I was waiting for you to realise the main switch, although can go anywhere, is made for the left side as the neutral link cable isn’t quite long enough for the right side and would only do it on a replacement when restricted. Nice install guys. I am wondering why the decision was made to have two circuits instead of the one when using such an expensive device? Doesn’t look like there would be much demand. Using 4.0mm on a 20A would still be far cheaper if there was. Would’ve made more sense if providing a lighting circuit

[@mikeselectricstuff]

I think it's called cement as it dissolves the material it's sticking

[@rhyswilliams1998]

Yep, fuses the surfaces rather than adhering them together.

[@pn8902]

Yep, turns them into one piece basically instead of the joint being pvc, a layer of glue and then pvc. Instead its pvc throughout the joint

[@Bin216]

In addition to the solvents, they usually contain 10-15% dissolved PVC, and I’ve also seen fumed silica listed as an ingredient (as a thickener, presumably also provides some reinforcement after setting, similar to glass fibre in injection moulded parts).

[@johnwaby4321]

Nice to see you using singles in the conduit. . . You may have to think about using metal white saddles ...I fitted some AFDD last year in an outside wooden horse stable. And the fire risk as Well . Installed in conduit with metal saddles .. 👍👍👍

Yeah, considering the board feeds one circuit with a single mod device, that 8 way board or whatever it is looks like overkill. Is it the smallest starbreaker board Crabtree do or something?

[@iancarbin567]

With the cost of those AFDD's, did it really need 2 radials or would one have been sufficient?

[@UhOhUmm]

Of course one would be sufficient. France for example allows 8 sockets on one 2.5 mm2 radial, they used to allow 12, other countries have no limits at all.

As a fellow electrician from Norway. We do the pipes inside the wall and cable outside the wall. And Cable pulling tape RUNPO 1 is much better.

41:25 Well the best way to test it, is flip it on and see if it goes bang or trips. Otherwise press the test button and make sure it trips, if so your test is complete. No EICR type testing here. Because almost all breakers are AFCI's and many are also GFCI's or combo's now, just a single test button.

[@TomGB-81]

Proper job mate! I'm surprised that considering you've done basically everything spot on, that you used a BW gland instead of CW. I know its extremely unlikely that water would get inside the SWA but, over many years its a chance all the same, same reason for installing AFDD's. Also I'd have looped the SWA up and down glanded to the top of the consumer unit, so there's no chance of any damp/condensation being able to slowly run down inside the SWA cable. Just knit-picky stuff!

[@jonl536]

What about if the supply cable going to the shed arcs and causes a fire?

[@FerroequinologistofColorado]

[@havoctrousers]

I do a lot of conduit work and I've never glued any of it. As long as you're fixing your conduit boxes and accessories to a surface I've never found it to be necessary as they hold everything in place. I also tend to assemble the conduit around the cables rather than completely assembling the conduit and then pulling the cables in. I know there's a reg about fully assembling conduit in the fabric of a building, but it doesn't apply for surface mount and I think it makes life easier. Very nice job, really like that green laser.

Did you not consider putting a smoke alarm in there too? No fly lead to the metal back box?

[@geraldelwood9660]

Another little tip for you : When boring holes through wood, use your impact driver instead of the drill. Especially important for bigger diameter holes in joists. It eliminates the kick-back torque from trying to break your wrist. Armeg Beaver cutters are designed to go in impact drivers.

[@geraldelwood9660]

@@JSPhi11ips That depends on how many bits of metal you accidentally hit on your way though 😂 But at least my wrists are still intact. I still have the same set, but then I only use them infrequently. One thing to be aware of is that once you get them started they have a life of their own. They will bore through dragging your impact behind them. If you pull back hard to stop them, they can be a bit difficult to restart because the pilot screw will not grip until it is pushed in to fresh timber 10mm or so.

Lovely job. But isn't using a 10.00 mm, CSA, SWA a bit of an overkill here? How did you arrive at your design current for the installation? Assuming your cable run wasn't extreme, VD not being a major problem, wouldn't a 4.00 mm SWA have been more than adequate and cheaper - considering you are feeding two 16 A radials only? To my knowledge the 10.00 mm SWA you installed has a current carrying capacity of 71 A, Ref Method D, (Table 4E4A, BS7671). You are only supplying a few socket outlets - so it seems like it's a bit of over-engineering. I would be interested to know your thoughts - many thanks. But really neat and tidy job, all the same. As an aside, did you at any point consider making the shed installation in to a TT System (earth electrode)? With it being a TNCS System at the origin of supply and the risks associated with exporting a PME earth to an outbuilding having to be considered by the designer. Just wondered what your thoughts were on this option?

[@davidbeakhust9797]

I have a shed like that, and because the walls are effectively boards laid on edge, log-cabin style, they expand and contract very significantly with changing humidity. Mine has moved seasonally half an inch in height, slightly less each season that passes, but it was really bad when the shed was new. There are two vertical runs, and one vertical drop to a light switch buckles in dry periods. Do you have any views on using flexible cable in such circs? For boats, flexible is mandatory, but because of vibration. I thought of this as I watched you meticulously measuring up the conduit.

[@robinwilson3510]

David, you are so right!! NEVER attach anything rigid vertically across more than one of a cabin's logs; leave at least one joint un-cemented in each run of conduit and ensure saddles allow conduit to move freely. Whoever fitted the shelf supports has seems to have insufficient expertise with log cabins. Such a shame as the electrical workmanship is very neat.

[@christipler5067]

I agree David, the cabin looks like a model by Tuin and on their website there is a lot of information on how to cope with the log expansion/contraction issue. Anything in the vertical plane must be fixed to a length of board that is only fixed rigidly to one log, the other fixings must be through a slot that allows movement. The consumer unit should also have been screwed to one log only. I also put loops in the wiring to allow movement.

@@jamesdyas542 you're right, old habits I guess. The boxes are exposed conductive parts, so I earth them (and the manufacturer usually tells you to). Given that both lugs are fixed on metal clad surface boxes, it's probably just fine without the fly lead.

@@havoctrousers yes there is always that. It says in bs7671 that you should install things in accordance with manufacturers instructions doesn’t it? It’s just that we rarely read them.🤣

Jordan, why the two 16A radials? I'm assuming the potential load on those circuits would be very low with just the use of lamps, so wouldn't one 16A radial suffice thus saving the customer £120 on one AFDD straight away? Or is there potentially a higher load being used in the archive at some point? Interested to hear your design considerations. Keep up the good work mate. Kev @ KRT

Just a thought, but possibly for some heaters so the paperwork doesn’t get too damp over the winter period? Also just incase the client decides to use a lawnmower or similar. Who knows what the client or any subsequent users may require...

[@artisanelectrics]

Yeah that’s the point of installing sockets so he can plug heaters in

[@tobysherring1369]

A tiny space like that - 1kw heater, 5A. Lighting, FCU, led, less than 1A. AFDD 16A.

The Crabtree AFDDs are £155 each on CEF. You could buy a fusebox board and all the RCBOs you'd need for a job for that!

[@cocoino2307]

I head in they might update our regs and make afdd s mandatory , if that goes they should become about 30£ each or less due to demand

I don’t think Fuseboard do AFDD’s do they? Are Fuseboard still using the ole RCBO’s with earth lead?

@@zjzozn no, these days they're type A single mod mini-RCBOs with no functional earth.

With regards to your Fluke 13a socket test cable, 0.45 ohms is definitely high. I use Fluke and mine is 0.13 ohms. This is the combined resistance of all three wires. It might be worth testing the resistance of all three wires individually. It might even be caused by a loose fuse carrier. I periodically test the resistance of all my test leads and adaptors and keep a record. It's then easier to spot if one of them is declining.

[@artisanelectrics]

Yeah good shout

[@tjfSIM]

I'm really interested in why AFDDs are not being more widely adopted and recommended by electricians. Had a feeling they've been mandated in the states (although maybe wrong). People always focus on the shock risk side of electrical safety, and obviously MCBs and RCDs do a great job from that point of view, but a huge number of electrical fires are caused by in-line faults and loose connections that aren't picked up by circuit breakers. Why are they not more widely used?

[@haldo691]

So the afdd's protect the circuits leaving the board what about the board it's self🤔

[@paullefur6213]

If my plumbing knowledge serves me correct, glue will does as it says glue two surfaces together, solvent weld or cement as your using melts and bonds the joint to the pipe, thats why you have a small amount of time to get any angles correct best to also twist the join back and forth to make sure the cement is fully around the joint allowing a water tight seal, yes I said water tight maybe in a that kind of building a moisture tight seal.

I work for AF Switchgear Ltd, we fit AFD devices within some of our LV Switchboards up to 6300A, they have multiple fibre optics that run around the interior of the switchgear enclosure, covering all areas of possible risk. we use a photography flash gun to test the device operates correctly, this simulates the flash of an arc, although i've never seen the MCB version, i would think there is an optic sensor within the connection terminal chamber of the device, a flash gun may be a test you could try when you are next fitting AFD devices?

Outside the corrugated cable is exposed to damage, for example: the sun's rays, a lawnmower, footfalls and even animal bites. A better option was to enter underground.

[@joemaldonado3]

here in the USA we use different verbiage... I don't yet know the UK words for these...: we have Ground Fault -- normally for Wet locations; and Arc Fault -- normally for bed rooms. and now Tamper Resistant plugs-- similar to the UK type. new entries require Surge Suppression. and now a four wire standard for 120/240- volt getup's (red, black, white, green/bare wires). there is a glut of resources relative to our USA's National Electric Code out there. happy reading !!!

[@paulbraham2638]

Out of interest. How many fixings did you use for the CU. Those log cabins are a fully floating design and the planks can expand/contract throughout the year. The instructions that come with them recommend not fixing anything to multiple planks, as it can cause splitting/warping. Just about to have a CU fitted in one myself and was thinking about fixing a backing board to a single plank, then getting the electrician to fix the CU to the board.

[@Colby_sparky]

I noticed you didn’t put an earth tag on the back of the socket box?!?

[@JJ-kr6ky]

Don’t know if it’s available in the uk, but we use a galvanised hat section here in Australia to offer some mechanical protection instead of flexible conduit. Virtually indestructible and looks neat too. Only real draw back is that it can be a trip hazard. Here in Aus. It’s available in 20 x20mm, 25x25mm 32x32mm right up to 100x100mm and probably beyond. Perfect for your situation where your cable comes out of the ground and on top of the concrete.

[@petermichaelgreen]

It certainly exists in the UK, BT openreach use it when running telecomunications cabling up walls and poles from underground ducts.

[@artisanelectrics]

Ah yeah I know what you mean nice idea

[@xenadu02]

Yeah in US rigid conduit of some kind would be required; you can't run cable unprotected outdoors nor in any indoor living space for permanent installation. Service drops must be around 15-20ft / 4-5m above the ground as well. Anyone could hit that cable with a weed eater, lawn mower, or just some kids screwing around. I'm surprised the UK code allows that. I've seen similar in other videos - one was installing 30 car chargers in a parking garage and it was fed by an outdoor rated cable with cable hangers along the building main entrance path which is just insane.

That cable roller could be improves by adding short, off cuts ( or larger radius 90degree elbow’s) of conduit on one bottom horizontal. Feed the cable through from the reels. The reels also need some sort of frictional restraint to stop them fee wheeling and unwinding uncontrollably.
