Thread: Wiring 3 phase

    All I want is one poxy 3ph socket good for 9kW, a meter and a circuit breaker. It's an blooming industrial unit fused 100A per phase, how hard can it be?

    I've just had the second electrician round and still no joy.

    First one I tried to get a budget job, got me nowhere. Said he'd do it for £750 if I got the parts in but wouldn't tell me what those parts were. Obviously doesn't want to do it, taking the piss.

    Second one eventually suggested a ballpark £250 plus parts and I said, "No problem, that doesn't even touch the sides". Got his attention, but apparently it was essential that I understood everything and if I dared to ask a question he had to start explaining all over again from where the power enters the building. He seemed terrified of electricity, I suggested he might be in the wrong job, perhaps that didn't help.

    Number 3 tomorrow. Anyone care to suggest another approach (shy of pretending to be a lottery winner or kidnap)? I'm running out of ideas.

    If you have a CEF or similar go in and ask for a decent contact, preferably one not afraid of electricity.

    Seriously some people who call them selves sparks are clueless.
    What you could do post a request on this forum, http://www.theiet.org/forums/forum/c....cfm?catid=205 and ask for some info from there. They a generally a good bunch and should be able to help you out. There are sparks on there from most places around the country.

    I really have no idea what the job is worth, but guess I'm just about to find out :tup:

    Glad your getting somewhere now. It does make a difference when the real tradesmen turn up.
    Now all you have to do is sit down when you open the mail:lol:

    The three quotes have finally arrived :dance:

    £417 + VAT, £536 no VAT, £1413 + VAT. (I can get the VAT back so that doesn't count).

    The £417 does involve finding some outdated 30 Amp breaker to fit the outdated wall panel. It seems to be available on fleabay at around the £15 to £20 mark so this is still the cheapest option. He's dropping by on Monday to make sure we get the right one.
    I'm getting all excited wondering what will happen when I plug t'bugger in

    I think I had better ask him which power switch will be nearest to the enormous bang if it all goes horribly wrong. Want to use the one furthest away so I don't leap out of my skin.

    Once switched on my plan of action is to persuade someone else to touch it and see if they get a shock.

    Next, the instructions say to cycle the main 5.5kW motor and see if it goes the right way round. Not sure if I want to do the button pushing or the looking.

    When that's done I will stop and plumb in the hydraulic oil chiller before I start moving the rams. I've bought a half horsepower suds pump to drive the coolant, 1 litre per second with a 6 foot lift sounds about right. I'm going to start by pumping a weak sulphamic acid solution to descale it. I removed a lot of lime scale from the flow control valves so the rest of the circuits are probably in need of a clean up.

    This will either be great fun or abject disappointment. I'll let you know...
