    I'm not sure it's something I would do, but the proof of the pudding is that despite it's looks it works and shows no sign of overheating. Not a very technical way of deciding, but true!

    Just reread the original comment, my reply made no sense!!

    The reason I say single phase is: - 1/ The incoming cable and the loop are too small to be 3 phase. 2/ I have never known anyone do a 3 phase loop as there is insufficient space in the crutch area of that type of cut-out to do it safely 3/ The loop cable is installed well under the bending...

    Messy Single phase supply into a 3 phase cut-out with a loop to a second 3ph cutout. Feeding 6 individual meters for flats I guess? Probably 60A fuses

    Illegal cabling(?) and strange box

    Got photos of one of the BBMF Spitfires though!

    Illegal cabling(?) and strange box

    Enjoy! I spent the day locating a fault on an 11kV cable (successfully) and missing seeing the Red Arrows

    Folk are getting stupider as time goes by!!

    Ah, not sure the incident occurred about 100 miles from where I am so I was reliant on brief notes on our fault management system. The looped service by the way saw both properties disconnected

    Folk are getting stupider as time goes by!!

    Unsafe by all accounts Main protected by 315A fuses, the connection fed straight to a CU with no intermediate protection, then (probably based on others I've seen) 32A MCB's feeding circuits to the lamp units

    Folk are getting stupider as time goes by!!

    Some from today The barn that was reported to us by the police as a cannabis farm and wanted checked for safety. To get power someone had illegally installed a new un-metered service to the barn by live jointing onto a 3 phase 95mm2 main passing by!! The service alteration where a builder...

    Factories charged per kVA?, why not get PF and charge in kWh?

    Poor power factor is seen as an issue, with turbo generators having to be operated purely for power factor correction. There are experimental steps afoot I understand to fit power factor protection at an LV network level in domestic areas to correct it at that level

    Factories charged per kVA?, why not get PF and charge in kWh?

    The charge consists of usually four parts Network capacity charge - to ensure there is sufficient availability of the maximum load they require Actual demand often measured every 30 minutes (it can in some cases be above the capacity which gets expensive Power Factor usually with an extra charge...

    electric meter box lock/latch

    Yes what non of the kits seem to have is the metal fixing plate that fits across the back of the door to hold the lock mechanism. Though I suppose if you could get a pattern you could make that bit

    "Stepping up" 1mm t&e to 1.5mm

    Certainly when I was training back in the '70s we were always advised to use 1.5 as it was physically stronger and less likely to being damaged on installation that 1.0 At that time the company probably employed 4 to 5 hundred electricians, so I think it had some experience in these matters.

    One for Westie

    The term used in ESQCR is "Reasonably Accessible" which varies on the situation. In that location I would suggest between 2.5m and 3m. But that brings in all sorts of problems using aluminium ladders in the garden. In theory the line should be covered by some written permission for it to be...

    High voltage meters

    A little bit of a dig finds that the no load "iron" loss for a 1000kVA transformer is between 1100W and 1700W OOK there is still sme way to go, but this is a start

    High voltage meters

    Yep! At the end of the day the HV meters will be measuring the No load losses of the transformer The LV meters will NOT be measuring his value! The owner needs to find out based on the spec of the transformer he owns what the expected losses will be. He then needs to take account of that...

    High voltage meters

    I'm sure that the OP, at the bottom of it all is worried about the threat of disconnection and the cost of reconnection,. As well as explaining the costs of electricity at what is a closed down site Whilst a discussion about the whys and wherefores of the discrepancy between the HV and LV is...

    High voltage meters

    he poiint to look at with the HV taarrif is that most are not just about units used! Most include costs for Network demand availaability Actual demand Power Factor Units used You need to carefully investigate the tariff the site is on with the electricity supplier and see the...

    Electricity Explosion

    ^^ What he said But bear in mind that HV lines are not safe to approach until they have been proven dead and connected to earth in view of the point of work/damage A lot of the remote switching equipment we use does not have a sufficiently wide enough opening to be classed as a point of...

    Please Mr, is this safe?
