    Highest Wattage Panel You've Seen

    Whats the highest wattage panel you've seen? and by who if you can remember? seen some Chinese ones at 400w and wondered if any of more well known ones have bigger output than 250w or some in the pipeline for release at future date. Might help for future planning.

    PFC Testing

    Hi all. Just a question which seems to get me a bit confused about PFC testing. I understand that the value of PFC you put on a EIC or any other form is the highest value of either the PSCC or the PEFC. Now when you get the reading on your meter (which is sometimes displayed with the Zs value)...

    Help needed with 3 phase Ze

    Hey can anyone help, I've got a EICR (Periodic inspection) tomorrow and just been told its a 3 phase supply. Am i right in thinking i just do L1-N-E, L2-N-E and L3-N-E then take the highest reading, also is it the same to get PFC????

    What's the highest you've recorded for a 100A fuse?

    Yes Maximum Demand again lol I just tried to make the title a little more curious to get people to look ;) Just playing with some maximum demand figures, started with 226A and got it down to 104.65A Just wondering what id the highest figure you have recorded for a 100A fuse? Is it actually...

    Ipsc and Ipfc at sub distribution board

    Hi, Hope someone can help. I need to test the prospective fault current at a garage distribution board (i.e. a sub board) but the no trip function of my tester will not work and trips the RCD which serves the garage circuit in the main board. As I understand it, the figure to take for...

    Prospective short circuit current test

    Hi all, fairly new to the forum so youll have to excuse my 'noobiness' as they say. I just watched this video of a guy showing how to carry out the above test. Prospective short circuit current test - YouTube This is taking place on a 3 phase supply. Does anyone know why he doubled the value...

    testing R1 + R2

    When testing R1 + R2 on a three phase circuit, do you connect each phase in turn to earth and test at other end? Record the highest value? Similar to what you test Zs on 3 phase but without the connecting? Cheers all.

    Zs testing

    Hi I have just tested the Zs on my ring final circuit... i got the readings 0.25, 0.32, 0.47 and 0.52 there are more but the readings were basically between 0.25 and 0.52 Ze is 0.11 and r1+r2 is 0.35 i get the same readings either at the front or the back of the socket so with the test...

    R1+R2 and Zs - Don't know where the light circuit ends!

    If you genuinely can't tell where a lighting circuit ends (due to the way in which it has been wired) I presume you would test for R1+R2 and Zs at every point and then record the highest reading?

    Continuity of cpc's on lighting a circuit

    Hi guys, I have got a pretty basic question to ask, but I just want some clarification please. When testing Cpc's (R1+R2 method) on a lighting circuit which line conductor are you supposed to probe in the ceiling rose? Is it the supply line, the switch line or the line out to the light bulb?

    1 circuit?

    hi, guys, slight confusion here, installing a lighting circuit in a barn. job is likely to be used for assessment so it's got to be spot on. Coming from 10A MCB in 1.5mm to 2 gang switch, one switch for each of a bay of 4 x 6' twin fluorescents ( both runs in 1.5mm ). Done the cable calcs no...

    Prospective Fault Current

    Hi guys. I just got the results back for my AM2 and I passed everything except the PFC. I now need to go back and do the whole testing proceedure again which I am gutted about. When I tested the PFC, I don't think I had three leads from my tester, I seem to remember only seeing two leads...

    pfc on 3 phases

    when prospective fault testing a three phase circuit do you only need to do the short circuit test only on the 3 phases in turn due to result being twice that of the earth short circuit current due to the line voltage being twice the value?
