    We had an electrician out yesterday to fix something in our kitchen. I asked him to check our built in microwave and he said the wattage would be pulling around 14.56amps. After he looked at the wall socket he said that this microwave should be installed on its own supply and not on a standard...

    TNC-S Supply but combined again at DB?

    Took a look at a block of flats today that has a TNC-S supply. Each flat is fed by a 2-core mineral insulated cable. The earth and neutral are then combined again using a henley block prior to entering the consumer unit. Has anyone come across this before?

    USA Linesman video - temporary supply

    As I'm getting rather bored of watching UK electricians on youtube, I've been watching our friends over the pond. This was rather an interesting watch on a number of levels, he goes to connect up a temp supply and finds it dead. I can't get over how he keeps prodding the live terminals with...

    I thought I took a photo earlier but seemingly not. Someone's fitted a joint box to move a consumer unit. It's a refreshingly neat job.
