I've installed an outdoor 2200W IR heater (also rated for bathrooms) in my bathroom which is connected to an outdoor IP66 rated switch and a non-latching RCD plug at the end of a 10m (2.5mm sq) artic flex outdoor cable.
The last 2 times i measured, the heater worked for 17 and then 8 minutes before the RCD tripped. Resetting doesn't work, I have to unplug the RCD plug for a while before it can be used again.
Everything is in-line and pretty simple to wire. RCD to 10m cable to switch to heater. What is tripping my RCD and how can I fix it? Some pics below.
Thanks a lot for your help in advance!
