    Queries on main bonding

    Just want to know everyone’s approach to testing bonding within houses. I do a lot of EICRs, and I would say more times than not I can never get access to the water bond as the stopcock isn’t accessible. Now in this instance what I’ve been taught since my times been out is to test at any exposed...

    Running Parallel Cables for 400A Sub Main

    Hi All, I’m after some advice. I’ll cut to the chase but I can give more detail if needed. A 400A sub main supply needs to be ran 100m, a pretty direct route on ladder tray. Instead of one large cable (I think it’s 240mm), I was looking into running parallel cables instead. I’ve not done this...

    Main MCBs replacing incommer switches

    In this Youtube vid it shows an electrical CU on the French/Italian border. One comment says it was done to Italians ways. One comment say it is normal to have 30A supplies, as was this.
