    A little advice would be appreciated.

    3.15A = 724 VA (@230V), so this will be the rating of the PSU, not what it will draw. The PSU will be sized to cope with the maximum load the PC could draw, e.g. if it had two floppy disk drives, two DVD drives, two hard drives, a high-end graphics card, maximum memory, multiple USB drives...

    odd pir advice

    As a responsible, but new, landlord, I intend to have my properties PIR'ed every five years, PAT done at each change of tenant, AND visual condition inspections of the electrical installation done by my letting agent at each change of tenant. Another landlord might be interested in having the...

    "Ring does not loop test"

    Thanks for the replies to date. I'm pretty happy with the report overall. I think they've spent a several hours undetaking the PIR, and they seemed to work efficiently so did everything within a few hours. Their report is clearly based on Appendix 6 of BS7671. They were selected on the basis of...

    "Ring does not loop test"

    Hello all, I'm a Residential Landlord, not an electrician. (I'm hoping not to appear on Landlords from Hell!) I've just had a PIR back with a Code 1 where the explaination is "Ring does not loop test". I know that they mean the Earth loop Impedence test (Zs for this circuit is shown as XX on...

    What's the problem with the MK Grid ones?

    Vans with "Testing ans inspection" on them.

    Someone once told me that when pairs of food items were listed, e.g. Fish & Chips, Ham & Eggs, Steak & Chips, etc., it was always the item with the most protien that was listed first; never the other way around. I've yet to find an example that breaks this rule! I wonder if there is the same...

    Whats the difference between an Interview and a Formal Discussion?

    Another distinction between an informal and a formal discussion is that the company will expect to be able to rely on information you give during a formal discussion; e.g. statements you might make about experience and qualifications. If any of these turn to be false, they need to be able to...

    interview with bt next week

    I wouldn't accept a job with BT; a friend has been bullied out of their job with them after 23 years! I know from my own extensive dealings with them, they are more disorgansied that a box of live frogs.

    Possible ?

    A good idea, but it will be more difficult to implement for devices not designed from the outset for automated testing. You might need some Optical Character Recognition capability, to read the device display. Why not invent the standard for all Electricians test equipment to be automatically...

    any opinions with this one??????

    I don't think you need to provde cables capable of carrying 100A to all units; there must be some diversity, you just don't know what it is yet. Cables rated to 50A should be sufficient for 99.99% of the possible combinations of tenants. It doesn't sound like the units are big enough to pull...

    any opinions with this one??????

    Non-electrician replying - but I have been a specifier of TP distribution networks for commercial installations. I'd definitely talk to the customer about delaying the selection of breakers until each tenant can confirm their power requirements. Until/unless you have some confirmed...

    self employment issues

    Tonys right, permanent employment is no guarantee of job security. I realised this ten years ago (different industry, but the principle's the same) - your job security comes from what you know and who you know, not who employs you. Self employment is a big step, especially if going down the...

    Help with new socket installation in Garage.

    While the Type B/C MCB mixup is probably the cause, is there not also a risk that the MCB is tripping because of a fault? Could the electricians on the forum indicate what tests the BT Engineer should carry out to determine that the motor and its connection is not faulty?

    Data centre, earthed floor?

    The bonding is required to take static build up from the top surface of the floor tiles away to earth. This requires electrical conductivity from the vinyl tile to the metal sheathing of the tile, to the pedestal head, and hence to pedestals themselves. As each tile rests on 4 pedestals, it...

    Advice on testing a critical circuit

    Large IT installations would hire generators and move the supply to the UPS over to the genny prior to dropping the power. This could be feasible for your customer. This site sounds unsophisticated and may not have their connection to the Internet covered by the UPS. So when the power goes...

    MCB used as light switch

    There is also a risk to the business if there are other circuits in the fuse box, e.g. what if someone's hand slips and they accidentally switch off a circuit, possibly not even realising they have done this. Or accidentally turn on a circuit they didn't intend to.

    Good practice?

    Much better to get in touch with the electrician and ask him to help get the customer happy to pay you. This should be easy if you explain what you were trying to do and how you'd like to be able to refer other customers to him. (Say it, even if you don't mean it). Once he's on your side; you...

    Hanging WET coats on the rail could be cause water to drip into the consumer unit.
