I have 6-6-6 triplex overhead that I'm running to a detached garage. At the weatherhead at the garage I'm going to splice 8 guage thhn copper to run down to the sub panel (approx 5' max of 8 guage at both ends of the run). This feeder will be on a 50a breaker.
Does anyone see any issues with...
Hi chaps. I have a potential install which is a 56kW micro array. The supply is three phase, but the array is going to be 380M from the house (yes that is the correct number!). Working to a 1% volt drop over that distance, we'd be looking at 240mm2 4 core SWA (£42,000 worth), and I'm told this...

Do the item number 'EC308' WISKA earthing kits fit into the WISKA combi 208 boxes (10109571)?
I've only ever used them in 308 junction boxes
thank you very much in advanced
Here's a question that I was asked earlier.
If you have SPDs installed in a DB is it permissible to terminate the main earthing conductor into the SPD first then the DB earth bar?
Or must it be terminated in the DB earth bar first then the SPD?
Does anyone have any thoughts on the best way to terminate an SWA into the new style flush CUs such as Hager's, BG's etc.? I ask as all seem to either employ oval or square knockouts, which is great for the surface boards when using truncking etc. but no great if you are trying to comply with...
Hello all, visit to site today to see in an install of a 315A 400V supply to a machine. Client mentioned previously they were going to use single core AWA cables from the distribution board to the machine so I advised them amongst other things to factor reg 525.1 and how they terminate the...
I'm no expert on split concentric (assuming that's what this is)......But an earth clamp doesn't seem the best solution to this (also as the earth cores appear to be insulated!
This is for an eicr on a sub main but I'll have to do the remedial work at some stage.
Any advice on how to...

I’m getting conflicting information from electricians at my works regarding the correct way to terminate SWA and more notably S/Y cable.
I was shown a few months ago that with s/y you only Earth the supply side of the shielding (like you would win data)
I was also under the impression you do...
