I'm guessing this is not kosher on the basis the connection can be quite easily pulled apart? Are there any regs on the subject? ( like there's NOT going to be!)

Nothing wrong with crimps.

I do not see any probem with properly made crimps - a proper crimp will NOT pull apart. It may pull apart if you use a crap halfords set of "scissor" crimps though.
One you get to main earth connections, likelihood is you will be out of standard insulated crimps and into larger uninsulated crimps.
What is the conductor size and what type of earth are you proposing to crimp?
But is there anything wrong with bullet connectors, not good to allow the earth to be disconnected easily, separate to the other conductors?
The crimps are OK, but for something safety critical like an earth, I'd not want easily detachable (tool-less) connections to it!
I think electrical earths require a continuous conductor between the earth bar and clamps etc.,
Ah. I read it as through connectors.
Bullet connectors are a no no.
Thanks Andy.
Er, bullet connectors are *supposed* to be pull-apartable and I'm concerned they may do so accidentally thereby disconnecting the earth.
230V motor grounding, 2.5mm^2 x-section earth wire. For the purposes of this temporary lash-up, I'm using the blue connectors. They ARE crimped properly, but It just doesn't seem right somehow to make this arrangement permanent.On Sunday 11 August 2013 17:58 Andy Burns wrote in uk.d-i-y:
Don;t use bullet connectors anywhere near mains. They are good for bugger all apart from your car radio,

There is no problem at all with what you are doing.
Well done crimps are better than screw terminals and you'd use those wouldn't you?
Bullet connectors are designed to pull apart.
As pointed out by Andy Burns over 2 hours ago
Either screws or crimped... all a bit academic if the bullet connector has been parted...!
Indeed. But if you want it make it less likely that they will pull apart when you don't want them to, you can always fold the wires back on each other and put some cable ties round them (the wires, that is) for strain relief. Almost certainly wouldn't meet any relevant regs, but it should

I shoudl clarify that I mean "crimped barrel connectors" NOT any sort of easily seperated connector.
No No and three times No!. Bullet connectors are not to be used on Earth systems.
Crimped with a good ratchet crimper and decent crimps are just fine as good as cold welding ...
I'm sure you did mean that, but your initial advice, along with an electrician's was wrong and could have been dangerous.

I think we all blanked out the "bullet" bit - my sanity filter certainly removed it as a "why would anyone do that - does not compute..."?
The important thing is that it has been clarified -
1) No partable connectors 2) Crimped permanant joints are fine if done with the correct tools.
Non-sequitur alert! I seem to have broken several otherwise-perfectly-intelligent people's brains with this simple query. ;)
It might be the similarity between butt crimps and bullet crimps. The former (permanent cable jointing method) are fine, the latter (demountable), not.
