Commericial laundromat washers and dryers disconnect

[hhsting]

I have commericial laundromat with washers and dryers.

For the washers and dryers disconnect would NEC 2017 Article 422.31 apply? If not then which article NEC 2017 applies?

422.31 will apply

422.31 will apply

Am I reading this right: So according to NEC 2017 Article 422.31 circuit breaker can be disconnect even if NOT within sight of appliance as long as the breaker is lockable?

Are the machines cord and plug connected, or hard-wired?

If you look at 422.31(C) carefully it doesn't mention the branch circuit device like (A) and (B) do. This would allow you to put a switch with lockable means in some remote location that may not make sense for anyone servicing to even look at that location for a disconnecting means.

Not sure if that was a mistake or if that was what they intended. You would think if not within sight they would want it to be the branch circuit device.

What do you mean? They all (a,b,c) allow circuit breaker not within sight to be disconnecting means if lockable??

A and B both mention the branch circuit device being permitted to be the disconnecting means if it is lockable.

C mentions being lockable but doesn't mention the branch circuit device.
