    3 phase low voltage??

    Hi all I was called to a job this morning where the 3 phase supply was showing low voltage on two phases? The voltages where L1-245v L2-110v L3-135v could anybody give any possible reasons why this was the case? I have handed it over to...

    Caravan suppły RCBO

    Rolec caravan hook up boxes, unsure of make of rcbo as they are labeled up as rolec but I doubt they manufacture them!!

    Caravan suppły RCBO

    The terminals are din rail connectors direct into RCBO, no screw terminals are used like we see in neutral bars, surely the decreased csa of the conductor could cause a high resistance taking into account these vans are only on 10amp supplies so are pulling very close to the maximum??

    Caravan suppły RCBO

    Do you think that the fact that no boot lace ferrules have been used in the boxes by the manufacturer that the fine cores of the fly leads which appear to be spread could cause a high resistance joint??

    Caravan suppły RCBO

    Quite possibly I'll be carrying out a few resistance test tomorrow on a few random rcds around the site. I'm starting to think this could be a problem with the manufacturer

    Caravan suppły RCBO

    Hi Dillb, not quite sure what you mean, are you saying there could be a high resistance joint between the suppły cable and the RCBO in suppły box?

    Caravan eicr's

    Trying for some work on a local site, you say it's unusual for a caravan to undergo and EICR? The site owner says he has had many case of RCDS tripping over the last few seasons and to put his mind at rest rather than having to call out an electrician every time, would rather have every van...

    Caravan eicr's

    Hi all, I appreciate this has probably been discussed and length previously but would like some advice on pricing of eicr's on static caravans, I'm only talking about the caravan installation itself (including hook up lead) the whole site it also to be inspected but this is a seperate job...

    Positive pressure fan installation

    That's exactly what I was thinking dave, are you sure you've not met this Q.S. Before. Hahaha.

    Positive pressure fan installation

    Probably right Dave, as you said if price was too high then job would've gone elsewhere.

    Positive pressure fan installation

    Evening everyone, I have just received a job through to install a positive pressure fan in a council owned tenanted property, I would be interested to see what sort of prices people are charging, only that the price I quoted was accepted but with the usual comments from the Q.S. "A little...

    Beast of a cooker

    Once allowing for diversity I would think a 10mm and 50amp D.P. Isolator would be fine.

    Floodlighting

    Sounds like a plan to me. Done a few calcs and looks like 4mm s.w.a. to cutouts then fused down from there. Just to double check am I right that ambient temp for swa underground is 20 degrees?.

    Floodlighting

    Exactly my opinion also, cables looped at base of each post. This is only a training pitch so doesn't need lighting to any league standard, the existing metal halides when working where more than sufficient so will probably be reused or replaced like for like. Was just interested in any possible...

    Floodlighting

    Probably the best solution, let somebody else do the donkey work. Would you individually fuse every individual floodlight at each post or just fit isolators? Job involves typical committee deciding on how much work they actually want doing to get lights up and running again, in my opinion new...
