Hi all. This is my first post. I'm in need of some help. This one has stumped most of the blokes on site. View attachment 32498View attachment 32498
All wiring seems fine. However, when the shower is in use it trips the RCD on the 63A bank on the opposite side. You can see from the pic that the shower is on other bank.
The electrician is adamant there's not a crossed neutral and everything works does work independently. We've isolated the upstairs lighting thinking it was something to do with that but yet it still trips the left RCD.
Has anything ever happened like this to anybody before and if so how was it dealt with. It's puzzling us how something on a different RCD can trip the other and not itself or the mains.
Many thanks in advice.
