According to article 210.19(a)(3) a 20 amp tap can be taken off of a 50 amp circuit. So correct me if i'm wrong, If I have a customer with only a 50 amp feed to a one piece range oven with an over top convection attached. Wants to replace it with a glass top range and mount a micro hood over that, I can tap off for that. Wanting to do tis is not out of lazyness. this is a second floor condo with no access. How often is stuff like this realy done? What if the oven and the microwave are on at the same time. (like during christmas) Is this realy safe to do, I like to sleep at night. Thanks

Re: taps
Assuming that you are referring to the tap rules I cannot see how you would do that. Unless you used a receptacle that incorporates a fuse holder you would be supplying a fifteen or twenty ampere receptacle from a fifty ampere circuit which the US NEC specifically forbids.

Re: taps
I don't see where Exception #1 to 210.19(A)(3) permits a tap to a microwave.

Re: taps
As said before you cannot do it because of 210.21 (1) Single Receptacle on an Individual Branch Circuit. A single receptacle installed on an individual branch circuit shall have an ampere rating not less than that of the branch circuit.
This means that the receptacle would have to have a 50amp rating and I dont think you will find a micro-mate that will plug into it.
But if it was a type (and I havent seen one yet in a home model) that was listed for hard wiring then I cant find anything that would disallow it as the code only uses the phrase "electric cooking unit" and this would discribe a micro-mate

Re: taps
I Know this sounds wierd. It just so happens that I had a customer were using this rule would have been usefull. I didn't just because it went against every thing I had been taught. That is why I am asking the above question. Although on page 83 of the hand book Article 210.19(a)(3) exception 1 Reads;
Tap conductors supplying electric ranges, wall mounted elecric ovens, and counter-mounted electric cooking units from a 50 ampre branch circuitshall have an ampacity of not less than 20 and be sufficient for the load to be served. The taps shall not be longer than necessary for servicing the appliance.

Re: taps
This would be true if this micro-mate was listed for hard-wireing but not plug and cord connected.
the key word is it must be listed for such connection.
