Hello chaps. Me again with a further question if I may To recap I have a TT system with an earth leakage that I haven’t had a chance to track down. The TT system is connected to an old Wylex fused board with a Crabtree VOELCB connected to an earth spike. I briefly borrowed an earth leakage...

Well I signed up to an EON tariff that required for me to accept a smart meter. They kept asking for permission for their guys to fit the smart meter and I just kept ignoring them. Eventually the two year contract expired and I reverted to the standard variable tariff and they never did fit a...

Hello chaps Just a quick question about an oil boiler replacement. I have an existing elderly Potterton oil fired boiler in the kitchen and basically in the middle of the house. It has a single wall flex stainless steel flue pipe that runs up inside a brick chimney. I want to replace the boiler...

Obviously you cannot do much in someone else's house but if that radiators a single panel, as it looks to me, then you could swap it for a double.

Not good but I would just fit lengths of 1/4 round beading to cover the gaps. Just tack it to the skirting board.

Did it have a steel crittall window.

Thanks for that. If they are of the same cable standard but just different size then is this something I need to be concerned about. Regards Stuart

Hello chaps A quick question here if I may about domestic power cables. The cables that run from the network providers fuse to my meter are 10mm diameter for the live and 6.5mm for the neutral as measured with a vernier calliper (not sure what that is in X sectional area). Does that seem normal...

When I did my worktops I used biscuits joints and clamp bolts. It needs some serious skill to do all that and easy to mess up. Don't really see how you can get a decent tight joint without clamping.

Thanks for all that chaps. One further question if I may: If the VOELCB test button trips the power can I take that as proof that the device is serviceable. Regards Stuart

Thanks for all your replies chaps. If non conductive inserts on incoming pipes, water and oil in my case and easily installed, were fitted then would leaving a working VOELCB in place provide a similar level of safety to an RCD inside the home. Thanks Stuart

Many thanks for your informative reply Bernard.

Thank you for that detailed reply. You say most of the fault current will flow through the N-E connection and very little via the earth electrode. My question is would that small amount flowing through the earth electrode build to a level that would eventually trigger the device?

Yes me again chaps with yet another question. As I understand these things the problem with those old VOELCB’s is that most homes have more than one earth and because of that an earth fault can bypass the device and prevent it from tripping. My question is would that actually happen in the...

Those old workmates are brilliant - don't chuck it away for goodness sake because you won't buy anything better. Repair is the way to go. My old workmate - I replaced the boards with bits left over from the kitchen worktop replacement - absolutely brilliant will probably last another decade or...

I had a look around the village and it's strange how you do not normally notice the mess that all those overhead cables impose on the environment. Anyway I've noticed that the houses that are furthest from the poles do have dual twisted cables so I guess they need to be tensioned more to prevent...

Thanks for that John and bernard. That explains things for me perfectly. John there are three other houses connected to the pole by overhead cables and they are all roughly the same distance from the pole at about 100 feet. There is one odd thing though. The cable from the pole to my house is...

Hello chaps - me again with a follow up question if I may. So I fitted the 30mA RCD no problem. Switched it on and then switched on the fuse box and the RCD immediately tripped. I pulled out all the fuses and RCB still trips so I am assuming I have some sort of earth/neutral leakage on one of...

Thanks will do regards Stuart

Thanks for the reply. As you say fitting circuit breakers to the old box adds nothing and they appear to be unavailable anyway. So thinking of fitting an upfront 100 amp 100 mA RCB at this time and then maybe swap over the CU later with MCB's and 30 mA RCB in the box and maybe a surge protector...
