    Additional consumer unit for shower circuit

    Hi, there’s no spare ways in the consumer unit so it requires Henley blocks and new tails to supply the 63a 30ma shower consumer unit. I take it I need to install 25mm tails into it? Or is it possible to downsize them to 10mm? thanks

When the RCD disconnects the circuit in much less current, why...
