    Split load and HI board question

    I've got a consumer unit to change which is tight for space. It's a neighbours house and when I did my board at home I used an 8 way wylex and RCBOS, this worked out ok but it might be a bit dear for the customer compared to a dual RCD set up. The only issue is the customer had a burglar alarm...

    Split Load CU

    I was discussing the wiring of split load twin RCD consumer units with a friend last night. I wire them with the largest MCB amps next to the RCD (first feed) then decreasing down to the smallest eg. 6 amps. He disagreed and said it should be the other way, smallest first. I tried to...

    Small East/West split - Inverter/meter advice

    quoting for an east/west split on a hipped roof (oh joys!) so can only get 5 panels on each roof. After reading some of the previous posts I thought that the Aurora 3.0 would do the trick but the minimum voltage is 156v. Thinking about 250w Yingli (35.1v) so this doesn't leave a lot of leeway...

    Split PV arrays

    The PV "bug" is catching and a relative of mine is considering solar PV. However, from a quick measure-up with them over the weekend, it looks as if they have two options. One seems crazy, but the "theoretical" numbers look slightly more attractive than the other more-logical option. The roof...

    On a new kitchen install the oven and hob are not specified yet and are therefore unknown to check MI. Most likely it will be a built under double oven, and a standard 4 ring ceramic hob. Is it beneficial to install separate circuits to oven and hob, or a single cable to isolator, and dual...

    Uneven East West split one inverter

    Looking to install 10 x 250w East facing and 6 x 250w West facing on one Sunny Boy inverter. Originally was looking at splitting 9 east 7 West but was told that would not work. A bit wary now - should the 10 East, 6 West split work OK? thanks Chris
