    higher Zs with RCD

    When testing Zs for circuits which also have RCD protection, what figure do you record onto your test sheets? when you exceed the max value for a specific MCB, due to the rcd. Do you just use a calculated value or do you actually record the value that you get even though it exceeds the max...

    Inverter reading higher kwh than meter ???

    Our inverter is reading about 6% higher than the PV meter. It shows we've generated 311kwh since installed whereas the meter only reads 290. Is this normal ? Im guessing it's probably due to cable/efficiency losses.

    8 commercial units, 8 meters on one set of deeds?

    I have been to survey a job and whilst discussing potential options we discussed a 50 kWp system on a barn and a 3 - 4 kWp system for each commercial unit. I feel that because each unit has its own meter and has its own user(s) it should be seen as 8 seperate systems all with the higher FiT...

    Very high prospective fault currents.

    Ze 0.02 giving a PEFC reading of 12.4kA which equates correctly; high but acceptable with fitted 100A BS 1361 supply fuse. However, PSC reading of >50kA. Instrument (Fluke1653B) checks out ok. Any ideas? Will be contacting supplier when I discover who the supply company is.

    Why is Zs higher than Ze+R1+R2?

    I've had 2 instances in the last week where the Zs measured result was higher than I would have expected. Firstly, a brand new shower feed, R1+R2 of .11ohms, *Ze (measured) of .31. I would expect a measured Zs of between .35 and .45 for this, yet it was .55ohms. Then yesterday, connected a new...

    higher voltage needed

    Just received a new lab oven that calls for 415V 60HZ 3 phase @ 45KW, the problem is that we only have 120/208Y available to us ( plenty of unused service). Question: Do I source a transformer or look into converting oven to run on 80A 208y?

    EU electrical safety standard higher than UK standard.

    I was asked by a client to put up a couple of Chrome bathroom wall fittings, bought from John Lewis. There was no earth terminal, only live and neutral. I rang JL and was told, that most bathroom lights, had no earth, as the cables were double insulated. Yet the shell of the fitting is metal. I...
