I am installing a light fixture - normally simple task for me (I"ve excellent lots). But on this one ns accidentally spliced the wire insulation top top the fixture wires too brief so over there is now too much bare cable exposed to where it would sign up with with the receptacle wires. Can I safely just wrap some electrical tape roughly each ar that is bare leaving of food the ends cost-free for the cable nuts?


Did you typical "stripped" instead of spliced? The tape is one solution. If the wires overall are saturated long, the excess exposed copper have the right to be cut off. Cut wires shorter must be done with cautious forethought.Disputing posts will soon follow.


Yes, sorry, i supposed stripped. The wire together a totality is NOT long enough and that is the problem. . . . So, now what?


If the cable is not lengthy enough, ns don"t understand how you might have too lot insulation stripped off? Also, code requires at the very least 6 inch of complimentary conductor at each splice point. Too lot is always best, you can constantly cut part off.

I uncover a preferable method being to cut off several of the exposed copper to where you have actually just sufficient to wire-nut ~ above a brief extension of factory insulated wire.


"Also, code requires at least 6 customs of complimentary conductor at every splice point. "

Not because that fixture wires.

The neater equipment is to usage a quick piece of shrink tubing come cover the ceiling portion. I choose to usage a warmth gun come shrink the tubing quite than a flame warmth source. I execute not understand the company temperature rating of the shrink tubing. It may vary relying on several factors and typically is not significant on the tubing.

Heat shrink is good. One alternative, especially if it"s a warmth fitting (it may have actually high-temp rated silicone wire, it"ll feel rubbery) is the braided "cloth" sheathing you discover in things choose toasters. It"s frequently called "H.O." sleeving and is generally fibreglass so an ideal for high temperatures.

That gift said, I"d use heatshrink. The voltage & temperature ratings need to be printed on it.

"The voltage & temperature ratings should be published on it."

Rarely, on only on longer pieces.

The ratings only apply AFTER the product is appropriately shrunk anyway.

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

I didn"t understand the ratings used post-shrink, I"ve constantly assumed the shrinking to be optional if friend didn"t mind a loosened fit (although I nearly always perform shrink what i use, and I"ve used a lot over the years.

This is the fibreglass sleeving I referred to earlier:


I also used a many this stuff when I worked for a medical digital equipment manufacturer:

Alan, this products appear to be industrial, and also not generally obtainable to the public. Do you have any type of links to retailers wherein these are available in reasonable quantities?

Where walk you discover this?

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

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

You can additionally cut cable, wire, shrink, etc. Into brief pieces because that the applications without needing to keep marking.An inspector might ask to check out proof the product is what girlfriend claim, but the most that friend would have in countless instances is a acquisition receipt.

Better go review the actual instructions the come with the products you use rather of guessing.

As friend say, Brickeyee, possibilities are you may not end up with a item in place with the requisite info. If ns knew something would need inspection, I"d make certain I offered a item with the markings. The being said, heatshrink is provided by manufacturers fairly often and also I doubt lock take together care. I expect the UL civilization test the or otherwise verify what the mfr has actually used.

I always read instructions, btw. :)

Kurto, I simply threw those links up quickly. Commonly I"ll questioning the mfr or look on their site for neighborhood retailers. Jaycar.com.au carries hobbyist supplies, Radio Spares (don"t know what they"re referred to as now however are usually an extremely expensive) - www.mouser.com is most likely your best bet. Friend can also get a the majority of this ingredient on Ebay and Amazon. Together for Hellerman sleeving, you"d have to inquire via the link. It"s sort of specialised but offers more flexibility and is much more durable than heatshrink, yet isn"t shrunk top top so probably doesn"t comply where a waterproof sleeve is required (they make heatshrink with a adhesive lining that provides it waterproof.)

Apart native hobbyist stores, electrical wholesalers usually lug lots the heatshrink and it"s cheap compared to the auto stores if girlfriend don"t psychic buying a pair of metres. The H.O./fibreglass stuff you can buy from electric motor rewind shops. It"s good stuff.
