Is this correct

[johnad]

I have a small fan heater over the bathroom door the flex from this goes trough a hole in the wall into a fused rcd on the opposite side the cable from this goes directly to the consumer unit also rcd protected.
Is this all correct to current regs ?
The heater has no earth wire as its all plastic.
I didn't have this installed myself as it was there when I moved in but I wish to replace the heater for a new one a simple job but is it notifiable work ?

There is no need for two RCD protecting this circuit, the one at the CU is enough. By the way what is the ratings of the two RCDs?
I assume (dare I) that the earth is missing from the flex/cable between Spur and fan?
It's a replacement so should have no issue with notification.

The rcd outside the bathroom door is 30ma and incorporates a 13a fuse
The flex comming from the fan heater only has brown/blue wires no earth as does the new one.
The connection point is fed from 2.5 t+e via a 16a mcb in a rcd protected unit
Would it be advisable to replace the rcd at the bathroom with a normal fused connection unit
Or just leave it as is ?

You don't need the second RCD providing that circuit is protected at the consumer unit, you must confirm that first.
The option is yours if you wish to remove it, for a FCU

That second RCD is not doing much harm.

Discrimination should not be much of an issue here.

You might be happier to leave it in place because research suggests that RCDs might have a failure rate of something in the parish of 7% therefore two in tandem might improve that to something between 7% and 0.49% of both failing - a more comfortable feeling?

Regular pressing of the test button might help guard against "sticktion" and keep this 7% lower too

Where I worked once we had a small disk array with drives that suffered from stiction, and wouldn't spin up. You had to pull them out (they were in hot-swap carriers), and then give them a sharp flick, as if cracking a whip.

Hoping all the time that you didn't let go of the thing....
