Stranded wires under screws

[peter d]

Intgresting, here is what the white book says.

That is interesting. I'll take that to mean that P&S's instruction must supercede the general UL listing.

The website shows it having a UL number

I don't see how it could be UL listed at all (the link says it is) if it does not match what the UL General directory says. I am at a loss to explain it and hope someone here (Jim D, I am calling you. ) can explain it.

I know, I looked that number up but it was not much help.

This is very strange .......... at least to me.

It is to me as well. Until I looked at the P&S website I didn't relize that the CR series receptacles were not intended to be used with stranded wire. I had always assumed (yes I know ) that ALL wire binding terminals on receptacles were good for both stranded and solid wire.

UL says they are.

Got to the party late...the CR discussion in full bloom...



Next question:
So which takes precedence:

UL or the MFG's info?

I know, that is why this came as a shock when I read it in P&S's information.

I have always used, and liked, P&S devices.

Thanks Celtic, your on top of it.

Has anyone emailed P&S yet? I haven't, and I'm not going to, but I know one of you nerds will.

So what is an inspector to do?

UL says it's OK, the manufacturer claims no.:-?

IMO this is a big issue, one that I suspect will have an easy answer that escapes me.

Great point.

I don't have an answer right now either.

:grin:

I'm trying to play catch up.....after the first post on CR devices...I went to the P&S site, find the info, wrote a reply ~ and then answered the phone.

When I hung up...I hit "Submit reply"....it looked like a train wreck in reverse...but I was now committed to posting something...ANYTHING....and there ya have it.

A slow ground ball to give time to catch up.

Because the customer does not want to pay for better devices?

good point, but a BR20 is what, $2, $2.50? Seems like any savings would be lost to the time spend twisting wires around screws and monkeying with fork terminals.

It takes me no time at all, no fork terms, no backward twisting, no little piece of insulation.

Would I rather the pressure plate type? You bet! :smile:

 

[Pierre C Belarge]

Are any receptacles rated to take stranded wire with fork terminals?

I did not read past this post, but most terminal screws on devices are not listed for fork type terminations. Google UL and the terms and you will find the info. This was another topic discussed at a UL meeting. I was very, very surprised to here that comment at the meeting.

 

[Pierre C Belarge]

Yes, according to P&S the CR series devices only accept #14 through #10 solid conductors, while the BR series will accept either stranded or solid wire.

HERE is a link to a page with information on the P&S CR series receptacles.

Most likely this may be because they only paid to have the product tested to the types of terminations as mentioned as opposed to pay for all of the testing that may be necessary to have a product listed.

Pierre I don't see what that has to do with it. Per the white book a UL listed receptacle is listed for stranded, if the manufacturer wants a listing they have to meet the requirements. I do not believe they can pick and choose which parts of a particular listing they want to apply.

Same here. If it squeezes out, I'll pinch the hook with needlenose pliers while tightening.
