Thanks for the three hour rule explanation for continuous operation. I upgraded my built in non-plugged electric furnace air handler to a 5 ton from a 3.5 ton and it had a 100 amp breaker. We put a current meter on it and it read 82 amps on high. It is a 2 speed, 42/82 amps. The 2 amps is for the blower motor. We were uncertain about the definition of continuous load until I watched your video. The heater will never be on high for three straight hours.

[@edwardmccormick7852]

In my opinion, think it’s a good practice to always run a Multi wire or two separate circuits for the DW & Disposal, especially in new construction and major remodeling. This video really provides the rationale, both the DW and disposal are fixed, but are also replaced / upgraded over the years. Two circuits will protect the option to upgrade, without having to rewire @ some point in the future. However, for homes with one circuit this video makes it perfectly clear what you can do.

You discussed UL rating for household appliances. How about commercial equipment? We are seeing a lot of equipment imported from overseas that are obviously not listed. For example, refrigeration equipment for walk in coolers etc. We always get asked if they need to be UL rated. As far as i checked, i do not see NEC requiring UL listing on those kind of equipment. What would your thoughts be on that? Sometimes these equipment will even require European voltages like 380 or 400 volts 3phase or 220-240v single phase line to neutral power. They will offer to sell a transformer to come along with it. It'd be great to see a video about tips and tricks for compliance. Your content and explanations are fantastic. Thank you.

My wife only knows one cycle on our fancy dishwasher. Hygienic with heat to dry dishes. Yep the longest and most expensive cycle. The motor probably never runs more then 10 to 12 minutes before going to a rinse cycle then heater that probably does not draw 10 amps so in my eyes you could connect the two appliances that never run motor never runs over 10 to 15 minutes. I have rewired kitchens during remodels and always but the dishwasher, garbage disposal and refrigerator on their own circuit breaker. Used to love when people spent tens of thousands of dollars to gut & update a kitchen from the 1930 or 40's and people refused to spend money to replace a 60 amp service & fuse box. Told them to please get somebody else to cut corners. Had some of these people that called me back to say they could not run dishwashet, garbage dispisal, hot comb in bathroom. Told them they had to hire somebody to split up circuits and by the way now that walls are closed in going to cost a lot more.

[@ericdevries3007]

Does NEC require that dishwasher and disposal circuits be sized for what future owners could reasonably install, or may the circuit be sized (smaller) for what will be installed initially? For example, a future owner COULD reasonably install a 15A dishwasher and a 1.25hp (12.3A) disposal. These are the largest sizes that are currently on the market. The dishwasher could be run virtually continuously for a party so needs its own 20A circuit. The disposal at 12.3A needs it’s own 15A circuit.

Nice 👍 my question would it have to be AFCI / GFCI protected? We have different views of this in my region… I personally would think GFCI would not have to since the outlet is not readily accessible? But would be required to be AFCI protected per Article 210.12 (A).

[@felixbruno8806]

GFCI required also 210.8 D.... 422.5 A 7

[@estevaness]

@@felixbruno8806 Thanks

[@J-Jim]

Felix has pointed out the GFCI codes for the DW. The disposal would need to GFCI’d under 210.8.A.7 since the receptacle location falls with the sink distance rules. They both must be AFCI protected because the outlet (in this case receptacle outlet) is in a kitchen, 210.12.A. Building Code does let you put the DW receptacle behind the DW. Since the receptacle will be under the sink, it is still readily accessible as long as you don’t need a tool to open the under sink doors.

[@chrismorz8541]

Hi Ryan great video as always, Table 210.21(B)(2) says for cord and plug 20A circuit max load is 16A, if the dishwasher and disposal are both cord and plug would this be true? Thanks again great work!!

I would place a saw drawing 14 amps on #12 copper to a 20 amp breaker because it would be just my luck to get a call back that the high in rush motor current would trip a 15 amp breaker maybe once a year. We were taught the 125% rule that all motors even the ones that only run a few minutes a day should be on wires & a circuit at least 125% larger then nameplate amps. Some times like with air compressors had to supply a breaker or time delay fuse 150% higher then nameplate amps. Good to see another well produced vid from you. Also do not believe that the code rule for kitchen counter top receptacles having at least two 20 amp dedicated circuits. Now with protruding islands off a counter top think it should be at least 3 twenty amp circuits. Saw houses where they have a 4 slice toaster, 30 cup coffee pot, blender, counter top toaster oven etc.

[@victorpoliashov2467]

WOW! Blown away by your explanation. You know as a apprentice 15 years ago I remember dis this with my JW, but it was sweeped under. I recently I was in this very position of suppling a DW and disposal from a single circuit, I was uncertain of 100% code compliance but you cleared that up! Just curious what about a disposal and the light over the sink scenario? I remember that being called by inspectors multiple times in my career. Would love to hear your thoughts

[@rupe53]

that's a tough call, but I would think that light might be a "fixed" application so just figure for the max load.

[@icevariable9600]

Remember, he said, "210.23(A)(2) Equipment fastened in place (50%). The load must not exceed 50% of the circuit rating if lighting, portable equipment, or both are supplied on the same circuit." So a 10A disposal should be able to work on a 20A breaker with lights, presuming the lights aren't greater than 10A load. But I could be wrong. I'd go read 210.23 and see what it says.

[@rupe53]

@@icevariable9600 ... point taken, but the max load on a 20 amp breaker is 16 amps, although there is some allowance for start surge on a disposal. I take that to read 50% is the allowed max for those fixed appliances. There's still 6 amps left for a light fixture.... although your local inspector may frown on it. Perhaps there's an exception if the light WITH the other things is still under 50%?

[@KrazyKajun602]

Hey Ryan, just to clear things up. If cord and plug connected equipment is limited to 80% of the circuit rating, then why do manufacturers make 1875 watt hair dryers, and deep fat dryers, toaster ovens and steam irons rated at 1800 watts, with a 15 amp plug? It would seem like they would be required to come with a nema 1-20P or 5-20P to comply with the NEC code for the 80% rule.

[@christopherlawler3033]

Both a dishwasher & garbage disposer on the same branch circuit ? ? ? I don't see any problems with this, so long as the nameplate ratings of both appliances do not exceed the rating of the branch circuit and so long as the branch circuit is dedicated to those two appliances (with nothing else added to it.) In practice, I also use a single 20-ampere branch circuit to supply electrical current to a common household refrigerator and a typical household microwave oven (up to a 1.2kW rating), since both appliances are not continuously operated (the refrigerator cycles on & off, and the microwave oven, for obvious reasons - is not in operation for more than several minutes at a time.) My interpretations of the CODE when it comes to two dedicated circuits in a domestic kitchen environment is defined as two dedicated appliance circuits supplying counter-top receptacles that are intended for the use by portable, cord and plug connected small appliances i.e. toaster, coffee machine, food processor, meat slicer, rice cooker, etc. larger appliances such as the microwave oven or a convective air-fryer (with a nameplate rating of 12.50 amperes @ 120V.A.C. or 1.5kW of electrical energy consumption or power draw should be placed on a different circuit dedicated to that appliance as would be the case above (with the household refrigerator only drawing 3 amperes (0.360kW) or less when it is cycled on.) Commercial/industrial refrigeration units may very well draw even more electrical energy (in excess of 10 amperes (1.2kW) in some circumstances) and would otherwise be handled as the same as a microwave oven, being that it would also require a dedicated electrical circuit in order to operate reliably and without overloading the associated branch circuit supplying it and causing the circuit protection to trip offline, causing the refrigeration unit to cease operation and the contents requiring refrigeration to expire. I honestly do not see why NEC Article 210.23 is really all that difficult to understand? Basic math skills are definitely required in order to sum up the total circuit demands needed to understand when loading up branch circuits used for supplying specific appliances or applications, such as that of what would be found in a domestic/residential kitchen or commercial food preparation environment, workshop, or any other environment where there is a higher than normal electrical demand. I almost always keep lighting equipment, light fixtures or luminaires & associated utilization equipment (ceiling fan(s)) on a separate or dedicated electrical circuit, apart from circuits supplying kitchen appliances & electrical receptacles or other convenience receptacles so as to prevent the affected area from being left in the dark, should an electrical overload or other electrical fault occur on one of those appliance circuits.

Thanks man this helped a lot!

[@court2379]

1 hp is only 6.1 A at 100% efficiency and 120V. Those name plates look quite accurate actually. 9.5A for . 75hp means it is a pretty inefficient motor, but likely puts out it's full rating. The main place I have seen the lies is on vacuums. I believe they are taking the stall torque and multiplying it by the maximum speed to get those those numbers, but the two don't occur at the same time so they are lies.

[@unlimitedbandwidth]

There's no such thing as a 100% efficient motor so doing a conversion of HP to watts and calculating amps from that doesn't really help since a motor is not a resistive load. Also, I'm not sure where you're FLA numbers are coming from but they're incorrect for 120Vac motors. 3/4HP is listed as 13.8A @ 120Vac per NEC table.

Oh...so each receptacle on the duplex can supply up to 16amps if on 20 circuit....(but you can't load the branch circuit up to 32 amps)... It is not stating the total being plugged into both. Is what the table means. What I think is getting me confused is how the tables description, uses the terminology" total cord and plug connected load in excess" should it not drop the word "total" and just state "cord and plug connected load in excess" The word total makes me want to add up all my cord and plugs connected loads.

Have to poke fun at hard working brillant Ryan but here goes. Heard of people coming out of the closet but never somebody coming out of a dishwasher. I always installed a dishwasher on thier own circuit breaker but now with combination AFCI/GFCI single pole circuit breakers costing close to $50 each would reconsider adding the garbage disposal to a single circuit. ( 12 guage copper NM on a 20 amp AFCI breaker. Dishwasher load calulation can be misleading. The motors in all the new dishwashers use less power then the heating element and believe the calculation should only use the 125% multiplyer for only the motor then add the ampere for the heating element. Heating element is purely 100% resitance load with 100% power factor and no locked rotor intush current like a motor.

What I am driving at is 15 amps worth of light is 1800 watts. (continuous load) If the CFLs are 20 watts each then that's 90 fixtures. If they are LED then probably twice that.

@@J-Jim ... good point. I can't think of any applications where a 30 - 60 amp outlet would not be a dedicated run to a single outlet. Anything over 60 amps will be a sub panel and broken out from there.

Also, a lot of that equipment is not "in" the dwelling unit.

[@rupe53]

@@WardCo ... but the circuits all start at the main panel FOR the dwelling so it's implied.

So I’m looking to purchase the Nfpa 70e but I don’t know what I should get , the standard 70e or the handbook which one has more detailed information and what is the difference thank you .

[@RyanJacksonElectrical]

If you're new to the subject, I recommend the handbook. The handbook contains commentary that you'll find useful.

Omg now I'm more confused, why if I have disposal and dishwasher in the same circuit the inspectors don't passed my inspection

[@erikolsen3611]

Ryan are you still associated with mike holt? i know that 3 way switch thing you mentioned came from him in one of his videos.

Good job

[@chrisbodiford6368]

ok a disposer it is!

[@icevariable9600]

You said that the dishwasher and disposal were "fixed in place". Then at 10:10 you said they were "fastened in place" and that "you're going to need tools to get those out. At 10:44 you said both your dishwasher and disposal are "fixed equipment, 210.23(A)(2) does not apply". So, you're using the terms interchangeably. However, the definition of "Fastened in Place" is found at NEC 625.2: "Mounting means of equipment in which the fastening means are specifically designed to permit periodic removal, without the use of a tool, for relocation, interchangeability, maintenance, or repair." Note that it says "without the use of a tool" and "periodic removal" which, disposals and dishwashers are not periodically removed. Can you clarify this? Also, id "cord-and-plug" pretty much equivalent to "not fastened in place"?

[@RyanJacksonElectrical]

Article 625 definitions apply only to Article 625 (EV power transfer).

[@icevariable9600]

@@RyanJacksonElectrical Ok, thanks for clarifying that. But can you still clarify the difference between cord-and-plug, Fixed in place and fastened in place? Maybe some examples of each, since they're not in Article 100.

Or do you know why there’s two hp rating on the disposer name plate? Thanks in advance.

It was 120/240, the second number was for 240. I had to think about it when I first saw that too.

While not relative to subject , andvyou are correct , manufacturers lie ...( 5HP shopvacs are my favorite).... please do your math on how much Amperage a 1HP motor draws .... 1 HP is 748 watts .... last I checked that's 6 Amp, not 15 Amp .... startup is in most cases is not considered a factor as it is momentary .... Disposals draw a bit higher due to possibly immediately starting under load (was surprised that your 3/4 specified 9.5A - clearly starting)

[@RyanJacksonElectrical]

In the US, horsepower of a motor is a measurement of OUTPUT power, which means nothing unless we know the efficiency of the motor. That is why we NEVER use it in the NEC and why we use Tables 430.248 through 252.
