    RCBO Ratings

    all test gear is merely 'an indicator' but some are more accurate indicators than others... LOL! 3-4mA is too bad, if you find something showing a steady 30-40mA, or more, then it will have sufficed it's function. As I said before, it really is worth altering your set-up to get rid of the 300mA...

    Need more sockets

    I installed 4 triple sockets for a customer many years ago, it doesn't look pretty. What I have done previously is make up an extension lead using dado trunking and lots of sockets - I had the parts to hand. You can buy multi gang extension leads, with surge protection, screw one of those to the...

    RCBO Ratings

    this sounds fairly normal, so add in a few mA from other appliancs in the caravan, and times that by 20 pitches and you can see how earth leakge can accumulate rapidly. Jiggling test leads can cause false readings, if the earth wire is bare copper and you touch it, you just discharged any...

    Electrical Instalation condition report codes details

    But lets be rank, the only reason the section numbers of BS7671 appear on most EICRs today is because they are auto generated by software packages. I would agree it's good practice to include them, but, for a customer totally meaningless.

    Yep, they are designed to be sensitive to protect people, but that also makes them sensitive to lots of little faults aswell.

    Sooooooooo Covid

    but probably the omicron variant which is a milder disease. I know peope who have failed to catch it from their partners when the Delta variant was rampant, I know people who have died, and some suffering long covid. It's such a variable disease it's really hard to tell how much difference the...

    Probably, but I don't want to be responsible for encouraging you to piddle about in live distribution boards. 💥

    RCBO Ratings

    the 'curse' of RCDs, otherwise known as right twits to fault find. So it sounds like you have a caravan with an earth leakage issue + earth leakage from around the site where something random is pushing the main board RCD over it's limits, pump sounds like a candidate, but isn't necessarily...

    PV Installation question

    you don't need the 300mm on shared edges, but it's useful to leave a bit of a gap to the neighbours so you aren't interfering with their roof in any size shape or form - saves arguments aabout any potential damage / leaks.

    PV Installation question

    I've never had any problems with WPD, apart from one predantic fella whose name I won't mention. What they like is notifying in advance before you fit the system for G100 installations. You will almost certainly need the limiting device, although you can ask to backfeed more than 16A - I used...

    Surge protection

    ok, I've given that full section a read. You are suppossed to assess the site for lighting strikes and generate a risk assessment. However as you are adding to an exiting installation, I'm not sure that would be relevent. App 16 shows SPDs as installed at site origin, so if you were installing a...

    Surge protection

    If it's an existing installation that's had no problems doesn't meet those criteria, and you aren't installing anything likely to be an issue, then the risk assessment is met for not needed. I'll go give that section a read before commenting further.

    Surge protection

    I read that as install where there is a serious risk, not as compulsory.

    Surge protection

    You are supposed to risk assess the site for lightning strikes, then decide if you need SP. Not sure if that applied to commercial, but I wouldn't be peeing about with it for an odd new cct. It's generally fitted to the incoming tails.

    Surge protection

    why are you thinking of fitting surge protection? Pv shouldn't affect it and I wouldn't start interfering with DC side, most inverters have some form of DC protectin built in.

    Average wage in maintenance??

    I would suggest tou read up on 3 phase motors and controls as much as possible before the interview. You could also possible offer to start on a lower wage for a year until you have learn't what yu need to know. When interviewing people, I was always more interested in attitude and willingness...

    Swa earthing

    In reality we probably don't, but it does tend to look neater. Putting the banjos on the outside of a box has always mystified me slightly

    Any recommendations?

    in that case just don't buy Chinese, it's Ok stuff, but european made gear will last longer. The other thing to perhaps consider is using 2 smaller turbines linked to the same inverter. I was looking at vertical units as these seem a little less imposing on the neighbours. Not sure were you...
