Is this acceptable?

Goody · Jun 11, 2011

I have earthed the metallic sheath of SWA cable by wrapping around the bare earth wire (sleeved off) around a bolt and tightened on to the brass eyelet using a nut as shown in the picture.

[ElectriciansForums.net] Is this acceptable?

Is this acceptable? or should I really crimp it using the one shown on the picture below and bolt it on to the brass eyelet?

Any feedback will be much appreciated.

Crimp it, the copper will squash over time and become loose, I also double nut it to make sure it stays tight.

And it looks crap!

Crimp it every time IMO have never be a big fan of copper wrapped around bolts.

Whats with the big nick in the cable bedding? hope it aint gone through any of the insulation!

As above always crimp. Also I always use brass bolt!

Amp David · Jun 11, 2011

Like to use brass bolts too, but each time i need some its seems harder to find them. Gone onto using the P nuts now though

Yeah crimps for me, and i would also be concerned by the scar in the inner insulation too!!

Echo the above comments re the sheathing.

I would normally put the bolt through the base of the enclosure as well, more secure that way.

same as above, and that of topquark - through the enclosure, whether PVC or metal, with brass nut and bolt and crimp lug!

Can't say I'd use a gutter bolt either - Whats wrong with a proper brass pan screw? Also I agree with Truckster about using double nuts. Sorry mate but even for purely cosmetic reasons I would be happy with that.

To be fair to the OP, the current syllabus of the 2330 states that "roofing bolts" should be used and not drilled through the case as to maintain the ip rating, tripe I know as I use brass panel screws and bolt thro but that is what is being taught at the moment

Fair enough if it has a suitable IP rating to maintain, that makes sense. That's one of todays lessons

I kno, I don't agree with it!!

another argument based on the supposition that rain falls up, not down. any IP rated box i fit, i drill a drain hole in the bottom. seen so many so called IP65 boxes half full of water.

nickblake · Jun 11, 2011

Im with tel on this one i always drill a drain hole at the bottom of IP rated items , MK master seal range have drain holes , unless its going under water that is , i have to admit i do use roofing bolts but instead of the horrible square nut i use Nylocks aint going no where then

Is this acceptable?
