I am installing a light fixture - normally simple task for me (I"ve done lots). Yet on this one ns accidentally spliced the wire insulation top top the fixture wires too quick so there is currently too lot bare cable exposed to wherein it would sign up with with the receptacle wires. Deserve to I safely just wrap some electric tape around each section that is bare leaving of food the ends totally free for the cable nuts?


Did you median "stripped" instead of spliced? The ice cream is one solution. If the wires as whole are sufficiently long, the excess exposed copper have the right to be cut off. Cutting wires shorter must be done with careful forethought.Disputing short articles will quickly follow.


Yes, sorry, i expected stripped. The wire as a entirety is NOT lengthy enough and that is the problem. . . . So, now what?


If the wire is not lengthy enough, ns don"t understand just how you can have too much insulation stripped off? Also, code requires at least 6 customs of free conductor at each splice point. Too lot is constantly best, girlfriend can always cut part off.

I find a preferable an approach being to reduced off few of the exposed copper to whereby you have actually just enough to wire-nut on a brief extension of factory insulated wire.


"Also, code needs at the very least 6 inch of totally free conductor at every splice point. "

Not because that fixture wires.

The neater equipment is to use a short piece that shrink tubing come cover the bare portion. I prefer to use a warm gun to shrink the tubing quite than a flame heat source. I do not know the company temperature rating that the shrink tubing. It might vary depending upon several factors and typically is not significant on the tubing.

Heat shrink is good. One alternative, specifically if it"s a warmth fitting (it may have high-temp rated silicone wire, it"ll feel rubbery) is the braided "cloth" sheathing you uncover in things prefer toasters. It"s generally called "H.O." sleeving and is commonly fibreglass so perfect for high temperatures.

That being said, I"d use heatshrink. The voltage & temperature ratings should be published on it.

"The voltage & temperature ratings have to be published on it."

Rarely, on just on much longer pieces.

The ratings only use AFTER the material is properly shrunk anyway.

Nonsense. The stuff ns use has actually the stats printed every few inches. Heatshrink that doesn"t have actually ratings published wouldn"t it is in UL/CSA approved, I"d assume, since display that the ratings and also approval number is typically a requirement, right?

I didn"t recognize the ratings used post-shrink, I"ve always assumed the shrinking to be optional if you didn"t mental a loose fit (although I nearly always carry out shrink what ns use, and I"ve offered a lot over the years.

This is the fibreglass sleeving I described earlier:


I additionally used a most this stuff as soon as I functioned for a medical digital equipment manufacturer:

Alan, these products appear to be industrial, and also not generally obtainable to the public. Execute you have any links to retailers where these are obtainable in reasonable quantities?

"The stuff i use has actually the stats printed every couple of inches. Heatshrink the doesn"t have actually ratings published wouldn"t it is in UL/CSA approved, I"d assume, since display the the ratings and also approval number is generally a requirement, right? "

Where did you find this?

While some marking is compelled under part NEC provisions and also listings, it is much from uniform.

It is not compelled to be visible after installation the would placed a rel crimp in fishing into concealed spaces).

You can likewise cut cable, wire, shrink, etc. Into brief pieces for the applications without needing to keep marking.An inspector may ask to check out proof the product is what you claim, however the many that you would have in plenty of instances is a purchase receipt.

Better go review the yes, really instructions that come v the commodities you use rather of guessing.

As friend say, Brickeyee, opportunities are you might not finish up v a item in place with the requisite info. If i knew other would call for inspection, I"d make certain I offered a item with the markings. The being said, heatshrink is supplied by manufacturers fairly often and I doubt lock take together care. I intend the UL world test that or otherwise verify what the mfr has used.

I constantly read instructions, btw. :)

Kurto, I just threw those web links up quickly. Generally I"ll ask the mfr or watch on their site for neighborhood retailers. Jaycar.com.au dead hobbyist supplies, Radio Spares (don"t recognize what they"re dubbed now yet are usually very expensive) - www.mouser.com is probably your ideal bet. Girlfriend can likewise get a most this stuff on Ebay and also Amazon. As for Hellerman sleeving, you"d need to inquire via that link. It"s kind of specialised yet offers more flexibility and also is an ext durable 보다 heatshrink, but isn"t shrunk top top so more than likely doesn"t comply whereby a waterproof sleeve is compelled (they make heatshrink with a adhesive lining that makes it waterproof.)

Apart indigenous hobbyist stores, electric wholesalers usually carry lots of heatshrink and it"s cheap compared to the auto stores if friend don"t mental buying a pair of metres. The H.O./fibreglass ingredient you deserve to buy from electric motor rewind shops. It"s an excellent stuff.
