It seems that some folks on the main site frown upon (this is the only direct indication I can find, but I've seen a few comments and non-upvoted answers that indicate this as well) the use of relays in house wiring, but why? The linked relay:
- is UL listed (not just UL component recognized!) for mains service
- can switch a typical branch-circuit lighting or single device load (most relay jobs are switching relatively fixed loads, vs a receptacle outlet)
- can be mounted to any junction box that has a 1/2" NPT conduit knockout via its builtin nipple
- and is not terribly expensive or scarce (about $30, and Grainger + several major electrical supply houses nationwide carry the RIB line)
Is there some weird Code-related wackiness related to relays in dwelling units? Or is it simply unconventional enough to make people squirm?
