I want to install a flanged inlet into a residential wall box.

Like this inlet:

to an existing wall box, like this one:
https://www.homedepot.com/p/Carlon-...trical-Box-with-Side-Clamp-B234ADJC/100315472


I don't see much of anything to connect a flanged inlet to. I don't want to add a external box on top of the existing wall box. Need it to be flush or close. Indoor, no cover necessary. I've seen some Hubbel parts that look close, but not quite.


Any way to do it?

Yeah, an L14-30 inlet that bolts up to a 2-gang box is practically unobtanium.

The flanged inlets you're looking at are made to mount inside equipment, however, that one has the c-UL-us rating, which means it can be used standalone. (unlike RU which means only as a component of a UL-listed machine).

I've heard of electricians making their own with a hole saw and a steel junction box cover.

Thanks guys. Wanted to be sure there wasn't something available. Figured someone here would know.

It's interior on an existing box. I just made my own, it will do. Had a hard time finding dimensions of the inlet (part arriving tomorrow), finally found them on McMaster.

The nice thing about McMaster-Carr is they have warehouses everywhere, they were doing the Amazon thing decades before Amazon. So for most people, McMaster is overnight even if you specify ground shipping. Of course, no McMaster Prime :) so you do have to pay for it.

And they have everything you can ever imagine and their huge hard backed catalog alone costs $15 to ship. :biggrin2:

Agree re McMaster, used them for many years. Whoever built their search engine carries high praise from me. Instant, quick, logical, works. The CAD software I'm using will even import the 3D CAD models from their site automatically. Need a screw, import it, done.
