It's a renovation. It was a little bit damp due to the walls being made good with hard wall. No different to rendering them in though. Just cheep crap I think.

6 weeks. Haven't even 2nd fixed the job yet! Got them from CEF. There's no bs4662 stamp on them and they haven't got the galv texture they look like shiny tin. Keep a eye out for these, could turn into a nightmare.

How long do you think these boxes had been installed for?

This came up on the BPEC course and I thought the same thing. Because System 3 contains both cMEV & dMEV I think by "local isolator" they mean the one next to the main unit on a cMEV. Seems to be open to interpretation like a lot of other thing in the regs. The important bit the second...

Thanks :)

Domestic Ventilation Complience Guide 2010 Table 5. 6.0 Controls A. Continuous ventilation systems should not allow the occupier to turn off the fan other than at the local isolator. Provision of an on/off function will result in the fans being operated intermittently and the required...

I'm from Devon and I charge 350 plus vat for a straight forward board change. If it's an old property or one that looks like it's going to be more work I'll quote more.

I havent done any tests yet will be in the morning. About 2m. To and from the meter. It always confuses me who owns/responsible for what?

Calm down mate i'm only talking in theory. I've put a new rod in alls fine. :Salute

I thought the table assumes Ze (L - E loop) of 0.8 ohms not L - N loop? How is the L -N loop different on a tnc-s and tn-s?

Its a puzzler alright. Off to work now hopfully someone will have shed some light on the situation by the time i get home;)

Evening all Hopeully someone can help me get my head around this. I'm looking at table 7.1 OSG. For the 1361/3036 45A radials on a TN-S system the limiting factor is sc, which means its limited by the line to neutral loop impedance (short circuit). But the TNC-S it isn't. Can somebody please...

Thanks. I dont like it when i cant see/find the rod which seems to be the case a lot of the time. headbang If i was to change it to TNC-S what certification would be needed?The NIC inspector told me once that i needed to issue an EIC for the whole installation when i renewed an earth rod...

If i use one mwc then what do i put in the Overcurrent protective device box because ive got the 30A in the cu 13a in the rdc fcu and then 6a for the lighting?

Hi All, Just done a small job as follows: Theres and existing 2.5mm feed to the garage spured from the back of a socket in the house. (Not a very long run volt drop, R1+R2 fine). I've installed an RCD FCU 13A in the garage to supply a dso with a fcu in line to the 1.5 for the light. My...
