How can I mount a relay socket (such as this one) to a junction box with a blank cover in a way that:
- complies with the 2014 NEC
- won't surprise the next electrician working on the circuit (as I suspect mounting it to the cover plate would)
- allows wiring to be connected without having to "stuff" the socket into the box with wires already attached
- and allows the relay to be replaced without having to detach the socket from the box?
(This is not quite a dupe of my other relay mounting question as this question deals with socket type relays while the previous one dealt with chassis mount relays, which shouldn't be used directly in mains wiring because they're not fully UL listed for standalone service.)
