Not sure exactly - it was already in place when I moved to the property 6 years ago - I suspect it'd had been there for a few years before that.
Thanks,

I have a shower that has been working fine for years.
This morning as soon as I turned it on the RCD tripped (not the fuse for the shower circuit itself)
I can reset the RCD, and everything else seems okay but as soon as I try turning on the shower it goes.
Nothing has changed fusebox...
