What is a butt connector?
And what does it do?
I'm asking because I'm looking at under cabinet lighting for my kitchen and there is mention of these.Hubby is an electrician(navy trained) but(groan) doesn't know what they are(even with a picture).

Re: What is a butt connector?
I don't know myself, but after a little google, I found this site ( http://www.radioshack.com/sm-crimp-o...i-2151268.html ) and came to the conclusion they were rubber/plastic insulating sheaths.
Basically, I mean those sheaths were you put the sheath on one of the wires, splice another wire to it, and heat the sheath to shrink it so it seals around the wires, and insulates them.
---------- Post added at 16:33 ---------- Previous post was at 16:29 ----------
According to http://www.tpub.com/content/heaters/...77-13P_431.htm I may be only half right.
You crimp the connector to seal it, not heat.

Re: What is a butt connector?
Since its under the crimp connectors section of there website and from what it looks like i'd of said its for joining two wires together.
It'll work much like a cheese block but instead of using a screw to hold each wire in place you'll crimp (deform a piece of metal) to hold them in place. With the sheath forming an outer protective layer.

Re: What is a butt connector?
Thank you very much for the info Stuart.That last link with the diagram really helped him to see what they are used for.
A greenie for you.

If your looking at under cabinet lighting I don't know why they mention these They are basically an insulated feral, more often than not used inside certain panels / looms of wires etc. The 'norm' for under cabinet lights is something similar to a kettle ( IEC ) led with solid or wired connections of a similar nature between them.

Re: What is a butt connector?
There's a selection of 'butt splices' here:
http://cpc.farnell.com/jsp/search/br...tt+splice&Ntx=
I can post you some yellow ones butt they are huuuge.
Note that you'll need an appropriate crimp tool to use these. If you don't have one then I'd suggest using a simple terminal strip instead - they can be cut down to any size.

Re: What is a butt connector?
They are crimp connectors, more often used in motor veicles to solidly join two wires, as opposed to bullets (male and female) which can be separated.
NOT recommended for mains wiring, but OK for 12v systems.

Why do you say NOT recommended for main use when that's one use for them, they ( I say they ) and their crimping cousins are made for panel terminations, motor terms etc etc I've used them on 525V 3 phase motors pulling daft amps, so they definitely are made for this use. But again, I wouldn't know why Incog has been told to use these, also wouldn't use choc blocks, get they right gear for the job

Shame you don't live on a boat.
I was thinking it may be a euphamism for a penis, in the context of homosexual-male-bed-based-gymnastics. But that's my mind for you

They are used for joining wires together. I've normally seen them used along with bullet and spade connectors in cars. The blue red and yellow colours denote the current load they can take, I think in that order, blue the lowest current load and smallest.

Re: What is a butt connector?
Actually, it depends on the cross-sectional area of the wire - although, inevitably, this normally corresponds to the current:
use Red for wire 0.26mm2 to 1.65mm2 (22-16 AWG)
use Blue for wire 1.04mm2 to 2.63mm2 (16-14 AWG)
use Yellow for wire 2.63mm2 to 6.64mm2 (12-10 AWG)

Yep, that's about the size of it, no pun intended
