Anyone seen a non-standard mains plug like this on a standard domestic washing machine? Why would you do it? Any reason not to replace with a standard 13A plug?
Can anyone tell me if a MCC panel is covered by BSEN 60294 and therefore is excluded from the scope of bs7671 as far as the scope of any inspection and testing of the fixed wiring for the installation?
Thanks.
Afternoon all.

Ring up
Ring down
Kitchen ring.
I was at a trade show the other day and got talking to a few people and they said they only use a ring in the kitchen. Radials up and down. Got me think what’s the standard? I know...
We have a working tube heater in a cupboard which we do not use. We would like to put a tumble dryer in the cupboard but there is no mains socket, as the tube heater is wired directly into mains, and controlled by a fused switch on the wall.

Hello all,
I am in the process of buying a house built in 2002 and I am trying to find out when it became standard practice to run neutral to light switches. The reason being I may look at having smart switched installed and having this already in place would make the job so much simpler.
Thanks
