Hi 480, Good question for those who want to know. Two switches, two solid EGC's, one power leg, one solid EGC. Slide a 410 over the three conductors and crimp in one second, to terminate onto each switch or back stab into wago. pretty quick. Faster than making up pigtails for wire connectors such as tan twisters or greenies. rbj

We had a helper on a big commercial job one time that used greenies to twist together the hot wires on some 277V circuits.:mad:

Guess who found it before we did - the inspector.:mad::mad::mad:

I've never purchased Greenies since.

Hi Mark,

I agree, Experience is the teacher. rbj

I worked for a guy when I was an apprentice that had us use these with the plastic snap on caps for all splices except for fixture connections.

For the fixture connections we used a connector that was brass with a setscrew and had a screw on cap. I think they called them Marr connectors.

Hi Tim,

The end-cap is the old butt-splicing method that generally is obsolete. Any contractor using this method now will soon have shorts in their wallet. 8].. rbj

Hi Larry, I know you are lurking out there. Maybe MC but not in Industrial-Commercial conduit ECG's unless you can detail how you have learned not using non-labor intensive self gnd devices. I am still learning after 1/2 cent. rbj

That was "conduit EGC's...."

that is like not buying receptacles anymore because some stupid apprentice didn't know the difference between the silver and brass screws.:confused:

O.K., I'll show my ignorance (not usual, I know)..
whats wrong with "greenies" on 277 or commercial or whatever.
I find nothing on the Ideal site that limits them. (shows 600v , etc)

1. The splice cap shown is an integral butt splice cap insulated for circuit connections and sometimes used for EGC bonding but not conducive to multiple NM solid wire connections.
2. The copper Ideal (Buchanan)410 or GB 410 is a crimp bond shown used as an end butt splice. If done by passing all EGC leads (3" extra) through the barrel...a single crimp efficiently ties all conductors together for terminating any multiple device bonding as in a 3gg switch box. (no extra jumpers are needed) This is a common for NM bonding practice.

Both methods are sometimes used for EGC bonding. The insulated end cap is used for line splicing on smaller conductor arrangements. The presentations shown are somewhat archaic for EGC bonding due to labor assembly time where there must be an additional jumper lead to a device hookup and additional circuit insulation application.

it isnt very easy to use greenies on stranded wire.and more often than not in commercial stranded is used.
 
Back in '95-'96 I worked for a guy that made us use those crimps on a condo project. I would use the crimper built into my Ideal linemans to crimp them, then flatten the side(s) of the barrel where the barrel didn't completely squish. They were okay, I prefer wirenuts, not greenies, but on rare occasions I'll use a crimp just for the hell of it.
 
Crimps are for stranded wire only and besides those crimps are horrible. I have really never found one installed that was secure. Wire nuts or greenies only. The ground is the most important connection anyway for safety. A poor ground connection will shower sparks upstream in a short to ground as the connection is poor and there is resistance in the connection.

While I don't like the use of crimp connectors on solid wire, the UL white book says unless the connector is clearly marked, it is suitable for use with both solid and stranded conductors.
From the Guide Information for "Wire Connectors and Soldering Lugs" (ZMVV).
Wire stranding ? Unless clearly marked "Solid,""SOL,""Stranded" or "STR" for a given wire size, wire range or wire combination, conductors in the range 30-10 AWG are both solid and stranded, and 8 AWG and larger are for stranded wire only.
