Presumably you're talking about big wirenuts here. I wonder how the pros/cons differ between these and the types used on #14 or #12 wire?

Heres a few pics of some old wirenuts i took out of a house i rewired, they were called "SCRUITS"

These were from a house that i stripped out, original wiring from the 40s(ish) i think

I used these wirenuts, which push into a grease filled tube, for an irrigation system (12v), only time ive ever used wirenuts. Heck i didnt know they were wirenuts untill i saw this post, ive allways called them scruits [Linked Image].

Sorry Paul,
I think that we may have a cross-over in terms, here.
A wire-nut in my terminology, is a device that traps two or more wires under a common split bolt and a nut arrangement.
Damn, I wish that I could give you a picture
of one, will have a look around.
Sorry for the mis-understanding!.

Wirenuts (or Scruits) are also known as Marrettes.

That picture of the porcelain Scruit reminded me of a big porcelain wire nut I have somwhere. I removed it from an electric Menorah and replaced it with a proper-sized modern plastic one with the steel spring.

The porcelain ones don't have that spring inside and can slip off.

Some cheap plastic wire nuts that come with lighting fixtures also don't (or didn't in the old days) have the metal spring inside either -these were usually the tiny ones meant to connect an 18-AWG conductor to a 14-AWG or 18-AWG to 18-AWG (inside lamps), just a spiral cut in the inside of the plastic.

I always replace these on sight...they're worthless.

Hi San,
Thanks for those pictures. The ceramic/porcelain wirenuts are the only type I've ever seen used in the U.K., and as you say, generally on old wiring dating from the 1940s/early 1950s. They don't have the wire=spring as found in modern American wirenuts, and were mostly just used in lighting fixtures ("botch" jobs not counted!).
