Hi EFLI. Last post of the day for me. I take your first point. The supply to the second doesn't flow 'through' the first. It simply goes into the supply side of the rcd and then off into the supply side of the second rcd. The second D.Bs earth is indeed connected to the first D.Bs...

Hi guys. Just to clear a couple of things up. The over protective device for the 10mm T+E sub-main is a 50A 1361 fuse. When i phoned the helpful bloke at the NICEIC he said to use BS88-2 fuse to work out the prospective fault current as per table in the bible. Therefore using 220A as that...

Hi John, Thanks for taking the time to reply. Yes, it really is a true EFLI. Mind you i have had lower! Yes, i did take the PSCC as my figure for calculations as that was the higher reading. I was entertaining options and feeding the second D.B off of the first D.B via an mcb would...

Yes BAN, not ideal at all. But that's what people get when they try to save themselves a few quid by doing a cheap job. They get comeback. Just spoke to the NICEIC man on the blower and he agreed with both proposals. Now to tell the client!

Hi John. That is indeed a true Ze. They have either got very lucky with one electrode or there may be multiple ones joined.

Hi guys, I have been doing a bit of testing today and need a liitle input if possible. The installation is TN-S at source. There is a 50A switchfuse which feeds two distribution boards in a B & B outbuilding. The supply comes into the first D.B (in one of the B & B rooms) into the top of an...

Thanks for the input guys. Is the homeplug solution not very good then? I was trying to avoid the extra cost of running a third cable from the house. This would be a different and more problematic route to the bt and power cables I am already running in. Kind Regards, Dave

Hi guys, This isn't really my field but i have a client that wants power run to a summerhouse aswell as provision for a phone line and broadband capability. The cable run from the house is about 70 metres. I was thinking of running a seperate phone line and for broadband i was going to maybe...

Looks like grid then! Cheers for your input guys!

Hi guys, does anyone know where I can get a 3 gang light switch that sits kn a double knock out box. Either pre-made or in grid. I know there are plenty of curve edge styles but I need one that has square edges so it matches with the existing accessories (marbo). It used to be a 3-gang dimmer...

Good point! I shall put in a 80a fuse in the switch-fuse. This will achieve small overload discrimination. Not that the client's installation will be going anywhere near that level.

Don't worry. I have sorted it now! Got a 2-module width cartdridge fuse to sit alongside the DP RCD. Thanks anyway! Dave

Hi guys, I have a job on next week which i'm getting the gear ready for. It is a TT system and a fuseboard move. The intake is being moved by the electricity board and they aren't sure whether it can be converted to PME until they get on site and take a measurement. The intake is going to be...

Cheers guys! I have ordered one off e-bay as i need it to complete my remedial works. Thanks again. Dave

Hi guys, Just did a testing report yesterday and need to know what type of mcb is present on the left side of the rcd. I need to source that particular make or a compatible design. Many thanks, Dave
