Mine too. A 3/4hp newer ISE disp and a Kitchenaid DW. Both on the same 20A circuit, NEVER tripped a breaker. And we use both a LOT.

I guess if you read it really closely, this rule doesn't address a circuit supplying only utilization equipment fastened in place.
I forgot about this, and I agree.
IMO there is NO 50% limit if the only thing on the circuit is fastened in place. You can have ten appliances on the same circuit, all fastened in place, if you want.

I'm still waiting on kontoose to tell me what code I should follow.

...Why, the non-anal retentive code, of course...

Oh, I get it. You mean the one you make up because you don't know the real one.
No problem.

I'll try that.

OK, so I did, and I found this:
Quote:
(2) Utilization Equipment Fastened in Place. The total
rating of utilization equipment fastened in place, other than
luminaires, shall not exceed 50 percent of the branchcircuit
ampere rating where lighting units, cord-and-plugconnected
utilization equipment not fastened in place, or
both, are
also supplied.


Did you find anything to support this:

Let me ask you this. How is this any different than having two large power tools, plugged into two garage receptacles, on the same circuit?

Yes, this code stipulation usually refers to the kitchen and breakfast room areas. (I.e, you can serve the adjacent breakfast room outlets, and/or lighting with any of the kitchen circuits...as long as less than, or equal to, only 50% of the over-current protection device is taken up by a "permanently installed" appliance, or unit of equipment.
It's a "cheesy code", but Limburger lovers...tend to change their socks more often than Cheddar nibblers.
I take it you're Swiss...considering the holes in your code knowledge...?

You'll have to actually give a code section if you want anyone to take you seriously...

Yeah, OK.
It's stupid comments like this, and not posting anything factual, that will prevent anyone from thinking you know what your talking about.

garbage disposal and dishwasher sharing circuit


so does the NEC code stipulate a mandatory amperage for a garbage disposal anywhere? like for example 20, which would sound like a hell of an overkill but i wouldn't be surprised if it did. i cannot imaging that a GD would draw more than 3-5A max ever considering that a circular saw even seldom reached 10 (e.g. if you are cutting really hard materials)

in other words, can i have a GD on a dedicated 15A circuit?

thanks
