Consumer Unit loading design question
I'm still working my way through the latest IEE regs (it's many years since
I last had to do it) but I haven't yet seen anything about loading design. If the CU has a 100A isolator must I ensure that the sum of the MCB trip levels is less than 100A or can I use a statistical method (root of some of squares) to combine the max loads on the basis that they won't all be maximum at the same time? TIA Dave |
