High curent car battery charger + car battery + Inverter, maybe?

So I've just installed a Pyronix Euro 76 alarm panel (Confiqured and running the system in the DEOL mode with 4.7KΩ for alarm and 2.2KΩ for tamper) in my new house and zone 4 which has two detectors wired in series according to the below (other than the tamper jumper on the second PIR is set to...

I think it was more difference is guidance from different DNO's than anything set in stone.

Not personally, but the people who did the lead replacement on my side of the meter did. It was lowish, but not sure how low. Biggest problem atm is if you have the kitchen tap running downstairs, the tap upstairs in the bathroom would barley dribble out, although I have not tested that that...

Thanks everyone. And yes, there would be no extraneous parts or any plumbing in my future shed. It's a small brick building with a flat roof what is about 4 meters away from the back of the house. I also vaguely recall on whether your allowed to export the CPC on a TN-C-S supply, also...

So in my situation, would you TT the shed or simply export the CPC via 3 core 4mm SWA to the Shed and possibly add a extra earth rod at the shed for extra protection?

Just I am sure years ago (arguably when my knowledge was less) I read online somewhere that you can export a TN-S supply to a outbuilding such as a shed, but can't do so for a TN-C-S supply unless you either TT the outbuilding or export a 16mm CPC from the main board to the outbuilding due to...

First with all loads turned off on all boards, measure the voltage between the incoming N and E. Providing that is 0V or less than 4V what is the limit of voltage present when doing a continuity/resistance measurement on my MFT1730, measure the continuity/resistance between N and E. Of course...

I might measure the loop impedance between Neutral and Earth (with all loads disconnected/turned off) when I am next up at the house and see if I get a reading very close to 0.00Ω, indicating a local bridge and thus TN-C-S.

So this is my supply at my new property and when I first saw during a house viewing back in July and before I gave it any real attention, I thought it was TN-C-S. Then a EICR later on I had done said it was TN-S, making me think it was split concentric and TN-S due to where the main earth...

Need to wait till the water company replace the lead on their side of the water meter as a problem has also been identified there. Even before I did what I did, when you opened the cold tap nearest to the new incoming supply, the cold flow rate would start fast and then drop off considerably...

I stand corrected, it was 25mm MDPE in, not 28mm. I realised that once I looked at the original stopcock had 25 and 15 written on each side of it, referring to the pipe sizes. Don't know where I got the 28mm number from, before I actually checked. Anyway I decided to proceed ahead and replace...

About 3.5 meters from the main 28mm to 15mm stop cock to where it splits at the T to feed the cold upstairs and the combi's supply. The lenth between the T and the combi boiler is about 1.5 meters and the lenth between the T and the furthest cold tap upstaits is about 3 meters.

Hi all, got a quick question regarding pipe size and flow rate. From where my new 28mm mains comes in blue plastic pipe and then gets reduced to 15mm at the internal stop cock and is all 15mm onwards inside, if i replaced this with a 28mm to 22mm internal stop cock and then run 22mm pipe to a...

Does anyone have a copy of the latest (5th eddition) Electrical Installation Design Guide on them and can look up the current demand assumed for a lighting outlet in a domestic setting? I recall it has been updated from 100W to 30W, but I don't have a copy of the Electrical Installation Design...
