Yeah, I’m waiting for an email from Power networks uk about a glastic or Paxolin replacement, but thanks lads.

I have been requested to upgrade a distribution board in a London building as someone tried to have a new meter installed and the EDF electrician said the old MEM board has aspestos between the bus bars and missing barriers etc. A few years back now I measured all the missing barriers on one of...

Well thanks to the Terrys, I was kind of asking you professionals why coz I don't know! Thanks to lamchamps, I'll try that.

I have a Vaillant ecoTEC 428 boiler which has been losing pressure for about a year now and it has been necessary to re fill once a week. I could find no leaks on the system but water is obviously going somewhere. I had a heating engineer work on the system and replace a failing pump about this...

I wouldn't worry about altering any wiring now, the sleeved black is in a twin and earth with an unused red which is cut short. This would be the preferred one to be used but we don't know its history and may have been cut short as its faulty. Just replace your fitting and switch and appreciate...

I guess nobody cares now but if both lights work its unlikely to be anything in the ceiling. Its a switching issue as it used to work before removing it. Switching the switch-line with the switch-feed is not going to do any harm and I'm sure it will work from what you can see in the ceiling...

Hi, It looks like the red sleeved black on its own in the switch (ie in the sleeved black in same twin and earth as the unused red) is really a feed! So, if you reverse this cable with the top red in the switch which has a loop over to the other common at the top and leave that red link in, the...

Ha Ha, yes I do, but college wouldn't have helped. I managed to work it out and it was the device specific number which was wrong as the manual that came with the board didn't mention my old ecoTEC plus 428 so I tried all British codes they gave... It wasn't a question of reading the manual, it...

Its an old thread but thanks, had the same prob and its work for me too.:D

An interesting and argumentative read, I had the same problem with the exact some ecotec plus 428 and followed all disconnection advice (except the hair dryer!!) I am an electrician but wouldn't get involved with this if it wasn't my own boiler. I finally decided to replace the whole board as it...
