Neither are pull-cord shower isolators.FWIW, I don't believe a contactor is suitable for use as an isolator too, it isn't really a secureable device.
Or cooker switches.
Or FCUs.
This is a house, remember.
If not, then every house in the country is full of switches which are not OK...Probably me looking at it from a EAWR pov.
Are those 45A ones securable? Or I suppose if they are under the control of the person working on the piece of kit they may be OK.
