Meltric connectors for 3-phase motors

[emiller233]

We are looking to use Meltric switch-rated connectors for some 3-phase motors on an industrial installation. don't think there are any issues with these since they're CSA-rated, etc. but what about free working space requirements? I don't think it's required since the connectors themselves are dead front so they really don't need to be treated any differently than a standard receptacle?

The reason I'm asking is these connectors would be mounted on the wall and you'd have to step over the motor to comfortably disconnect this connector.

Any concerns with LOTO?

They are great for lotto...the male end has a place to install a lock so it cannot be inserted into a receptacle.
