It was (In my opinion) established back in post 13 by chunky that it is a voltage trip. What has not been proven is that it is still functioning as such, it could be tnc-s and ottermill is just a (faulty) isolator. Without knowing if those two earth cables are in separate connections, ie. across...

Best you look up what the term means in that contex then.

You are correct, 1mm2 is all that is required. Work safely now!

You need a Home Office Shield, Google Hager Home Office Shield. Cost pence.. There are dozens of shades that will fit a standard Batten holder.

See post 34 !

Jolly good, now relax and give your gf a hug.

If you have it connected as in post on. 5 then as has been asked is the programmer/ timer calling for heat? ie. Set to perm on or 24hrs.

OK just wanted to be sure that red was in third hole. Yel in 4

Hi Show us a better pic of no.2 so we can be sure which cables are in which holes, it's not obvious at the moment.

As it's all on a single Tarrif (24hr) it should never have been left as a dual set-up. I agree it wants the consumer unit correcting to reflect this and 2nd (LH) switch rewired or removed.

PME is a 5min job once they have ascertained the network is suitable, most are. You have what appears to be a TN-S Earth there, if that has been confirmed as Ze too high then PME is the way to go. Usually at no charge as its not your responsibility on the incoming side of meter.

Ive only ever seen dual taraff boards with two Main Switches BUT labled as such. No different to having two cu for whole installation. On peak and off peak. As pugwash said can we have a picture of the meter area including tails etc.

If you want PME then it's up to the DNO to supply it, your electrician cannot do it.

As you have no storage heaters, have the points been converted to 13A sockets? If so then maybe the consumer unit has been doctored to reflect this.

In the past it was always the consumer that was responsible for their earthing. If the distributor offered a earth terminal you can/should use it.
