Additional consumer unit for shower circuit

[Mabro22]

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

You could size the tails to the load but what about future additions to the installation? For example new circuits for EV/PV etc. Rather than a dedicated shower DB maybe a smaller 6 way DB to allow for expansion.

Thanks for the reply, that’s a fair point I’ll say to person I’m doing the job for. Thanks for the idea
