    3 phase conundrum

    Got that, ta. As you say a quick look at fleabay brings up lots - both this (older?) type: ….and this (newer?) type: As you say, it'll look pretty gash with them mixed…………….. and I've already got plenty of that in stock :( PatsPatter

    3 phase conundrum

    Ah ha!! Mechanical. Nearer my skillset. Might I suggest trying a backup of an old fashioned, imperial 1/8" allen key. It's actually 3.17mm and might just make all the difference and save you digging about for a torx bit and bashing it in. If you do try it, gently grind the ends of the hex to...

    3 phase conundrum

    ………….. but if the TP board has a 63 amp and the CU a 50 (electric shower - and the max I'm ever likely to need), then won't the CU go first and leave the TP alone? PatsPatter

    You've not had to deal with npower too much, then :mad:

    3 phase conundrum

    Please explain. Please don't take offence, I'm only trying to understand but surely: If there are 3 consumer units, each with RCBO and a MCB for each domestic circuit, isn't the short circuit option catered for? A MCB on the supply way to each consumer unit, within the TP board, would protect...

    3 phase conundrum

    OK. Ta. Assume you use RCD/RCBO with the same meaning? Schneider et al seem to. As you say, a RCBO on every outgoing circuit is going to be expensive. 3 smaller, decent quality, (Amd 3 compliant!) consumer units, fed from the TP board, each with a RCBO, instead of the present item, might be...

    3 phase conundrum

    …… have I crossed my internal wiring/written the wrong thing? Perhaps I should try asking the question in a bit better way: Would you expect to see a RCD on the incoming ways to the cabinet - similar to this? If the above is all correct, excellent! My original question/concern came from...

    3 phase conundrum

    My brain said it would upset any protection device on the supply side of the TP board if differing loads were applied to the phases. Happily, if I understand correctly, it won't. All good news. Thanks The TP board, fortunately, isn't in a cupboard, it's in the corner of the utility room and...

    3 phase conundrum

    I believe it is for the off peak……………. but would only appear to supply the off peak immersion. PatsPatter

    3 phase conundrum

    This one? Which rises another question: Can the "lovely Schneider 12 Way TP+N board?" be used as a complete replacement for the whole distribution schebang, including providing supplies for TP machine tools? If so, no need for a replacement for the plastic consumer - unless you're meaning...

    3 phase conundrum

    ……….. in which case, it'll get changed. Now. Anyone want a 'heritage', one owner only, plastic consumer unit? PatsPatter

    3 phase conundrum

    Err… aren't most of them, these days? Ooerr, error! There not, are they. Hmm, now you mention it, it does look a bit nasty, I agree. It wasn't the sparky's fault, though. PatsPatter

    3 phase conundrum

    Thanks for the advice ericmark. The 'farm electrician' option sounds about the best. I'm surrounded by farms. The 3 phase panel is a good one, I've paid (quite a lot) for it, it's well OTT for the job but that never hurt. I'm not without experience, or knowledge, having run many three phase...

    My thoughts exactly. Both options applicable.

    3 phase conundrum

    Here yer go The meter and all the terminal blocks are new, fitted a couple of months by eon when they replaced the old meter. That was done after the new consumer unit, etc was fitted. The MEM isolator is the one described and switches the off peak units. The incomer fuses are all 60 amp, not...

    3 phase conundrum

    The property we are renovating has a 3 phase-fed, off peak, ducted, warm air heating system - and it works surprisingly well. It has a single phase immersion on the off peak as well and a normal tariff daytime top up. That's the easy bit. The house is a being extended and completely rewired...

    The dreaded Hotpoint WD440

    Hi all. I've (SWMBO has) got the dreaded Hotpoint WD440 flashing light syndrome. I've isolated it to F08, which comes out at something like "Heater Relay Stuck' Tried the heater itself, which has no problems, checked all the contacts and the 'ECU' board for problems and can't see anything, no...

    Boarding and bracing?

    Thanks, tony. All noted. When you say ''buckle' do you mean as in twisting along the rafter length, or the whole set of trusses rolling over in the direction of the ridge, like a stand of dominoes?

    Boarding and bracing?

    Thanks, noseall. A fair bit to digest :-) If you're referring to the bracing as shown in the photos, it's only there to locate things whilst we put the trusses up. Apologies but not quite sure on that one. Could you elucidate a little, please. OK, that I can appreciate but...

    Boarding and bracing?

    OK, ree, I understand. Thanks for the effort, though. Incidentally, when you say 'neither of which is being braced as I would do it', I assume you are talking about the manufacturer's diagrams - not the way they appear at the moment?
