Hi guys,
I am carrying out a full install to one(top) of two flats from a converted house. Originally the house had only one incoming service head (single phase)to the property, but the new landlord decided to contact the DNO about upgrading the incoming service possibly from a 3 phase to one...
I am starting a rewire of a 4 bed maissonette next week. The meter and original c/u is by the front entrance, but the client wants it moved up to the first floor, which will then be near his front door. I want to keep the supply C.S.A at 25 mm, and obviously I will be incorporating a switched...

Hi, just wondering if anyone can help me with this?
If panels are fitted onto building that is not the main incoming supply location.
i.e. Farm house has the incoming supply and meter.
Remote building (barn) is having the PV array installed onto it.
If the distribution cable that runs from...
If there is concrete floor and the first sight of the rising main is behind the kitchen sink the other side of the house how does everyone get around puting in there earth cable? Are we restricted to zones running cable the cable, can it go outside instead of replastering and put it in a...
Hello all. Never seen a cable service head like the one in the flat I've just moved into (AEI - from the 1960s?). It's 3 phase (60amp fuses), but only feeds two flats (mine and the guy downstairs). Have cleaned the filthy contacts on the live cable head fuse for my flat, and also cleaned...

I need to arrange for electric and gas tobe reconnected in a property. The incoming supply gas pipe is next to (as in 2-3cm) to the incoming electric. Is there a requirement for separation? As this is an existing property is it ok to reinstall in the same place, or will one need moving?
Hi,
Can anyone suggest where I can get info on a mains incoming isolator? It has to be a changeover type to allow for a backup generator to kick in if the mains fails. I am looking for manufacturers or any type of info.
Cheers,
Need some advice, Can I move the incoming mains and meter (which is fixed to a wooden board) one meter to the side without getting the local leckie board to come out and charge me 900 quid? All the seals on the meter would remain intact as the wooden board would simply be re attached to the...
I am doing a lot of periodic testing at the moment and I have come across 3 or 4 properties which have no incoming earth.
Is it the responsibility of the service provider to now provide an earth or should I just put in an earth electrode.
I know previously they never had to provide an earth...

When I pointed out that there...

Each room has a maximum load of 50Amps
66 rooms X 50 Amps = 3,300 Amps
Not everyone will use every electrical appliance all the time, so we can reduce...

I recently was testing a flat and found that the 6mm Mains earth to water was not accessable but the valve for incoming is so may be able to test from board to incoming for a result but do Elecsa officials want to actually c the bonding position as its one of the assessments for elecsa??I...
