So if I'm reading 422.31(B) correctly, all 300+volts-amperes or 1/8+ horsepower motors need to have a disconnect means. So dose that mean ovens, dishwashers, microwaves, pool pumps, etc. need to have the same disconnect means?

Don't forget, plug and cord counts as a disconnecting means

ya, I got that. But if they were permanently connected, It would need to be in sight of the panel, or have a lockable breaker, or some other means of disconnect? I'm a little confused. Have I been missing these on inspections??

Almost all motors need a disconnect unless less than 1/8 hp. Electric water heaters need a disconnect at the water heater or shall have a lock on the circuit breaker. Personally I think the lock at the overcurrent protective device will never get used in a residence. We always have the disconnect in sight of the water heater.Ross Lovato said:
Although ranges and ovens require a disconnect it seems that no one in this area enforces a lockout on the cb.
