Dw and Disp on 15amp

[Cavie]

Is there any code requirement to prevent Dw and disposols on seperate 15 amp Circuits? I have been doing them on seperate 20 amp circuits for 35 years but I am learning of much cheaper ways as of late.

Legal as long as the load is 15 amps or lower.Also note some will share a 20 amp circuit for both.And that disposal is a motor so it could even be on #14 and have a 20 amp breaker.

Agreed.

And that disposal is a motor so it could even be on #14 and have a 20 amp breaker.

This, I'm not so sure about.

 

[Jim W in Tampa]

Agreed.


This, I'm not so sure about.

310.16 i believe as a motor it qualifies as 20 amp protection.

If it were technically an "appliance" and not a "motor", then that would not be correct. "Appliances" are not listed in Table 240.4(G).

Since they are mentioned in Article 422, I tend to swing with the "appliance" train of thought, myself.

Just got through with one. 14/3 to a split duplex, one switched for disposal.

I'm with George IMO this is an appliance.
