Re: sparkys- is it legal?
said by John Galt:Curiosity: Why a 60A disconnect? The upstream CB protects the wire that goes to the disconnect, that wire is of proper gauge (If at 40A or lower). Anything connected downstream of the disconnect is protected by the 15A fuses.
You'd have to use a 60A disconnect with fusing to 15A, or, if you use a 30A disconnect, replace the upstream CB to no more than 30A.

You forgot protection for the disconnect...
Disconnects are rated for 30A or 60A...so those are the choices. You cannot put a 30A disconnect on a circuit protected at more than 30 amps.

said by alkizmo:While a fused 40A disconnect may exist as a specialty part, the next larger common rating is 60A (which will be easier to get).
