Can someone provide literature on the proper amount of rubber tape that should be used on a burndy?

Burndy what? They have a pretty big line of products. Though I'd guess you need to look more into the tape manufacturer to determine how much tape to use for a particular application.
 
A Burndy? Rubber tape? :sick::sick::sick::sick: It's been said a million times before, but if you are still using those methods, you are living in the stone age. It's time to get up to speed with Polaris connectors, Ilsco Clear Taps, or whatever brand you prefer. Heck, even Burndy makes their own version of them.

I don't buy the material :dunce: :dunce:
 
varnished cambric tape is just used because it makes a splice more durable and is more resistant to environmental factors?

Should have been more specific. I basically was looking for the amount of tape that should be used when making repairs or connections. The article on "taping a lost art" was very informative.
 
Someone once told me something along the lines of....You need five wraps of Electrical tape to repair romex or a frayed extension cord? Also said the tape should be applied to the thickness of the cable..

Just trying to see how much tape should be applied

Cambric tape is used to make a splice more durable/soften sharp corners, but also keep the rubber tape from melting into mechanical connections making them easier to get apart later:D

We always called them split-bolts or kernies (perhaps burndys and my hearing is shot.)

Cpinetree's 1st link had exactly what we did -- until polaris came out (although we still vinyl taped the caps.)
"Split bolt connection. Protection of a split bolt connection begins with installing the connector and wrapping it with two layers of varnished cambric tape. Next, wrap the splice with four half-lapped layers of rubber or rubber mastic tape. Complete the job by over-wrapping with at least two half-lapped layers of premium vinyl electrical tape."

My boss always called it "friction tape" but I realize it was "cambric" now.

Polaris or equivalent for the win. Much easier to allen/hex wrench than cutting through tape IMO.

There is such a thing as friction tape. Some old timers used it for connector wrap, but that's not what it is for.

Seems even the leading manufacturer of insulating tapes doesn't want to provide concise use instructions...

Cambric, particularly varnished cambric, is useful in mechanically covering sharp edges and points to keep them from cutting through insulation.
It uses durable cloth fibers held together by a solid binder. It is very stiff.

Post looking at some images, it was indeed cambric tape which he called "friction" tape.

Are polaris (or similar) connectors listed for wet locations? i.e. parking lot light ground boxes or is there a scotchkote like product to wp them?

The "standard" Polaris connectors are not, but there are other types that are - they have a "boot" for each conductor port that seals around the conductor. Some you must use a specific conductor size to get proper seal, others you trim the "boot" for the conductor being used.

Depending on the type - you might have to use all ports in order to keep the entire assembly "sealed"

Thanks kwired!

Apologies to the OP, if this wasn't apropos for the original topic.
 
We have used the polaris blue's in the past but they have very limited wire range so you end up stocking way too many.
Polaris blues excel if you need to join more than 2 wires.

If you only need to join 2 wires:
Recently I have been buying the Ilsco USPA-350SS-DB they are big, but usually size isn't an issue in a hole (adult jokes aside :p)

They are good for #10 through 350mcm

In lieu of cambric (friction) tape, I have taken to applying good vinyl tape with the sticky side out, and the smooth side against the connector, making certain to have two to four layers on the sharper corner, and to cover the entire exposed conductive metal. After that, apply the rubber, and then coat the rubber with vinyl with the sticky side against the rubber tape.
