    EV charger SWA isolator switch

    I am considering fitting a car charger using 6mm SWA to a new isolator switch in the meter cupboard and then 6mm T&E to the CU. It would save running the SWA all the way to the CU. Does anyone else do this and if so, which isolator is best for SWA? Thanks

    32 amp rotary isolator

    Anyone know if there is a reg in regards to supply going in to the top of a rotary isolator. We are changing the isolators over for ac units, long story short they won't reach the top terminals now, so feed can only go in bottom. Just a 2.5mm 3 core swa. Cheers

    Setup: Consumer unit fed via sub main from a 60A fused isolator switch. This is connected to the service head MET via a 2m earth connection. How would one go about both calculating and documenting the Zs? Would you be treating the fused isolator switch as it’s own db and therefore be...

    I don't do PV, so not overly familiar with specific regulations. Yesterday I was changing a consumer unit, and the isolator for the PV was adjacent to the consumer unit. Due to needing a bit more space, I had to move this isolator a few cm and noticed it was single pole, switching L only. A...
