    Wylex 80A 30ma rcd - and known issues?

    Hi folks, carrying out an EICR yesterday. Board is a split Wylex (main switch with the rcd covering half the board). All circuits are on the rcd side. Problem I encountered was trying to take 'no trip' Zs readings, the rcd always trips. The meter (1520) is definitely on the correct setting...

    Unbalanced 3 Phase Loads

    Had an enquiry from a customer who recently moved premises to a similar sized building 100 meters from the old one. Their electricity bills trebled immediately. I have data logged 4 DBs for 2 weeks and nothing sticks out other than wildly unbalanced loads on 3 phase DBs i.e. L1=38A L2=18A L3=8A...

    Would you say I could use B type breaker here?

    I have a big place to work on here. Have come across a long lighting circuit where I need to repair/extend damaged end of the circuit. There are 8 PL type Florescent loads distributed evenly. Due to the (measured & validated) R1+R2, since the circuit is probably ~>60M long in 1.5 T&E, I need...

    Balancing a 3 phase load

    I have a question on balancing a load. We have 3 cabins with the following loads: 10kW, 8kW and 3kW, supplied by a three phase supply. Each cabin will have it's own supply. Is there a simple way of balancing these loads, or is it possible?

    diversity- commercial kitchen

    I'm curious as to what diversity any of you may apply to a commercial kitchen. All electrical appliances. So far I've added everything up and total max demand before diversity is 220amps. I've applied 70% overall at the mo but just wondered what others would think.

    Using rotary isolators for switching loads on and off?

    Hi Can you use rotary isolators to switch resistive loads on and off on a regular basis (talking 18KW load here) I personally thought not, that it should be controlled through a contactor but I have seen another installation that is using isolators thx Bigfoots
