can someone recommend a flanged inlet for use on residential portable generator installations (or alternate solution). right now i need a couple for 4w 20A. so far i found the 50A variety at grainger for $100 up, not including matching connector.

this is the part of residential generator jobs i dislike. my suppliers all have transfer switches and thats about it.

i did a search but didnt see anything on this. thanks.

What you are looking for is a NEMA L14-20 flanged inlet.

L for locking, 14 for 120/250 4 wire, 20 for ampacity.

Ask for this at any large supply house, they can order it.

No L14-20 is cheap but certainly you can beat $100.00

All manufactures use the NEMA designations.

A 15 amp duplex at a house would be a NEMA 5-15R.

5 for 120 volt 3 wire, 15 for ampacity and R for receptacle.

Here are some Leviton part numbers.

L14-20 120/250 20 amps

Leviton number 2415 for a Flanged inlet

Leviton number 2413 for a matching cord cap.

But any manufacturer's NEMA inlets will fit any other manufacturer's NEMA cord cap.

I found a non brand name L14-20 flanged inlet for $21.00 by doing a Google search.

thanks iwire. sounds like what i need. i'll also check to see if they make an enclosure with an inlet for this purpose. the homeowners' generator came with an enclosed indoor version.

If you need onesey-twosies maybe these people can help:

This is a 20-amp 120 volt inlet:

I've dealt with them before....certain stuff can be expensive but at least there's no minimum order

Are you're talking about relocating the inlet flush plug on a Gen-Tran type panel, kind of like the one in the post above just L14-20?
Gen-Tran (and others) makes exactly that. http://www.gen-tran.com/Merchant2/m...mp;Category_Code=PIB&Product_Count=0

Is this what you mean?

that may be what i need but i'm not familiar with that particular one. its priced right for sure.

i have been buying 200A GE tranfer switches and then piecing together an enclosed, flanged inlet for the generator cord using the connectors mentioned above.

the job i am doing now has an enclosed inlet that came with the generator, which will be installed at its location. most generators do not come with them however and i havent found a local supplier for them yet.
