My RCD keeps tripping on my electric towel
I did have a smart switch (Shelly1) wired in so assumed it was that, but I have now removed that and still tripping
This means it's either the socket (a fused flex socket) or the heating element itself
Note, it's tripping the RCD and not the MCB
How can I work out which it is, and why would it be tripping just the RCD - research suggests water ingress which I guess would be possible for either tho more likely in the towel rail...
