Hi,
I almost always use a fused disconnect for enclosures, usually class J and rely on the Bussman SPD publication to help with sizing the appropriate fuses for the disconnect sizes, since I mostly (99% of the time) deal with motor control.
Is there a trusted publication for Molded-case circuit breakers that is similar or a sizing chart? We have a customer that is requiring a circuit breaker for the main disconnect rather than fuses.
I've found this schneider electric one:

but it seems to be all I've found thus far. If anyone has a great resource, please share!
