Hi all, level 3 qualified sparky here, just getting back into it after some time out.
So, what is considered best practice these days when installing a metal clad consumer unit.
Are all these Fancy Dan cable glands actually required or are they just another money spinner.
I've found if you have a lot of cable going in the top, using multiple 20mm knock outs looks crap.
Older style cu I used to just run some trunking across the top which looked good, then use grommets or bushes to go through.
Also the new fire rated meter tails glands are an absolute nightmare to prep, same as the twin and earth shaped ones as they are barely big enough to get the cable through even without the gland tightened up. Any trick to these or are standard glands considered acceptable alternatives.
Last question, I'm installing a consumer unit where meter tails are going up inside a cavity from the meter box - joy.
Replacing with 25mm, but do I need to have a gland going in the rear of the box, or is grommet strip deemed acceptable with some fire sealant or foam applied in the remaining gap. Any tips on good stuff to use
Cheers
