Been bailing Scotland out since 1707! Even with the oil money Scotland deficit is very large. We could stop the debate here though if Scorland continue to send us the electricity in exchange for the money đ

Reform the Barnett formula so citizens of Scotland get the same spend as England/Wales and you can have it!

Should we go with kingspan or it pumped?

Tell the sparks heâll be running his cables from above. Ridiculous idea to put them in the screed when not absolutely necessary -
Ground array: future project, what cables
Mattg4321 replied to Post and beam's topic in Photovoltaics (PV)
Much better installing a duct with a rope through. -
But the scam that is MCS still has to be complied with to get SEG payments. As a sparks, the amount of absolutely shocking PV installs I see is frustrating. Itâs not cost effective for me to go MCS for a few systems a year, however Iâm just about to fit my own system (which will actually be done properly, unlike most MCS installs!), which I wonât be able to get SEG payments for. Ridiculous.

Also worth looking at DIY Kitchens. Better quality than Howdens imo, having DIY fitted both. The only downside being the delivery can be a bit of aggro. Theyâre usually cheaper than Howdens though.

I donât want to do that either!!

I canât be doing with changing batteries all the time personally

Youâll need to ask the suppliers/installers of whatever blind you go for. Imagine it will need power inside the window recess, probably at one end or the other. Iâm thinking of using the below when we do our extension, but not got round to looking into it properly, so please update the thread if you do the legwork for me!!! https://www.poweredblinds.co.uk/electric-roller-blinds/serene-electric-roller-blinds/

Youâll want 2x flexis right the way up into each socket if youâre doing it that way. Make sure you can actually pull the cable through it though. Mostly that stuff isnât smooth on the inside and can be a pig to pull cables through more than a few meters. If youâre going to all that trouble though you may as well just 1st fix the ring entirely, cables and all.

In an ideal world donât run the cables through the floor void where they are more susceptible to rodent damage and damp. Drop them down from the ceiling void above if thatâs an option? Easier than messing around with flexicon

Total Heating Total Control wiring issue
Mattg4321 replied to Ray Shields's topic in Consumer Units, RCDs, MCBOs
Heâs correct in that itâs against the regulations. However in practice itâs unlikely to cause a problem at a domestic level with relatively low currents. Youâve also got issues there with basic insulation of the meter tails being visible and cable thus not mechanically protected. The meter tails are not properly supported and also quite likely IP rating to top surface of consumer unit not to IP4X. Nothing major, and all could be argued C2 or C3 depending on exact circumstances. It might just be worth getting someone to tidy them up - doesnât have to be original inspector, you just append the invoice\certificate for the work to the original EICR to show the remedials have been carried out. -

As far as I know itâs not mentioned in BPG4. Might be hard to change someoneâs mind on this though as itâs ultimately the inspectors opinion. https://www.electricalsafetyfirst.org.uk/media/2depcuen/best-practice-guide-4-issue-6.pdf -

Eddy currents maybe? That being the case though a C3 seems more reasonable if no ill effects are observed and itâs been in service for that long. -
tails in individual conduits to meter?
Mattg4321 replied to andreas's topic in Consumer Units, RCDs, MCBOs
If steel conduit then no because of risk of eddy currents. If plastic then I donât see what the conduit is offering. Can you run in SWA as it sounds like meter tails are not ideal here? -
The whole thing looks like a shambles to be fair. Need to get hold of a good electrician to come and give you some advice. Seems like the last few havenât been very good, including the PV installers shoehorning a Crabtree MCB into an M2 board. OT slightly, but why are solar installers nearly always so bad? MCS scheme is a total mess imo.

PME has the downsides youâve listed, but itâs also a very cost effective way of achieving very low Ze. If we went down the route of TT earthing everywhere, it would then be routine to rely on the operation of RCDâs for fault protection. I come across countless RCDâs not operating properly/at all every year. Iâve only very rarely come across a lost PEN conductor. Both situations dangerous. TN-S earthing is probably the best, but not done anymore. This can fail too though. A supplementary earth rod to TN-C-S (PME) systems looks likely to be brought in and would be a good idea imo. FYI neutral/earth bond relays are needed to give neutral a reference to the earth. Without it an RCD will not operate correctly. Itâs a slightly separate issue to loss of PEN conductor, which wonât usually matter when in islanding mode as grid is switched out.

Better still get it swapped for a switch fuse (you canât achieve selectivity with MCB upstream of MCB and a fault could trip both). Obviously only if cable type and routing allows. As above you need an electrician. Good chance this is just build up of âearth leakage currentâ if the RCDâs in consumer unit donât trip though. Easily verified with insulation resistance testing and an earth leakage clamp meter.

What will the window cleaner charge ...

They usually use âpure waterâ or similar like https://www.spotlesswater.co.uk/locations/ -
Anyone here fitted any large white sliding patio doors? Or even Bi-Fold doors? It seems the strong trend for a while has been for colours - especially anthracite and black. Weâve got a 70âs box weâre extending (2 storey), with materials to match - brick and concrete tile roof!! The wife doesnât really want white patio doors - she thinks black looks much better. I tend to agree, however⊠I donât like the idea of mixing black doors with white windows on the same side wall. I also really donât like the idea of black windows on a 70âs box - it just looks wrong to me and Iâm convinced itâs going to date really badly and quite quickly!! Thatâs only my opinion! Back to the original question⊠would be great to see pictures if you do have them. Bonus points for lift and slide and around 4m wide on brick!!

Those rates sound ok to me, but I donât know the local area. Here in SE England I charge roughly ÂŁ300-350 a day and mark up materials by 20%. This covers the cost of sourcing the materials, sometimes having to pay my account before I get paid by the customer and also the cost to replace or repair materials should they be faulty. Iâm happy for customers to supply materials, but if theyâre wrong and Iâm hanging around, theyâre paying for my time and if theyâre faulty and I have to return to replace then, again, theyâre paying for my time. It sounds like a lot of money, but after all the expense of running the business, periods of quieter times, no holiday, no sick pay and no pension it doesnât work out to be as much as youâd think.

If youâre on economy 7 then that teleswitch is still in use. Itâs what switches you from peak to off peak rate. As above though I believe the signal will be turned off soon and youâll need to move over to a smart meter to use a dual or multi rate tariff. In any case you cannot remove it. It belongs to the energy provider. They would have to remove when replacing the meter. The black box your arrow points to is the incoming service fuse/cutout. If you pull the fuse, aside from being something youâre not allowed to do, and potentially dangerous, youâll have now power!!!

Not in my experience. Nothing like that high. Perhaps thatâs under certain circumstances. Like when they are run continuously at full rated current or something. Failed inside what timeframe? I fit hundreds of RCBOâs every year. Probably not far off 1000. I probably get 1 or 2 failures a year, even including devices fitted years previously. Admittedly though most people donât use the test button! So if youâre including failure to operate under fault conditions then the figure will be higher. I assume you guys are thinking of total failure ie no power to circuit. As above itâs different if they are subjected to substantial current flow. The reality is that the vast majority are only having to deal with 1 or 2 amps at the most either all the time or nearly all the time. Electric showers and EV chargers are the biggest culprits for causing RCBO failure.
