Jacuzzi bath wiring Discussion ThreadJacuzzi bath wiring Electrical Advice

Should a jacuzzi bath be wired in H07 flex? Wired one recently and spurred off the ring, just took a twin and earth cable off the spur and into a ip65 box under the bath to join onto the flex. But now I’m thinking should I have used h07 flex for this? Maybe over thinking it lol!

Installed AICO Ei2110e modules some 6 years ago and used their RadioLINK bases to link one set to others in the extension. No issues until recently when a myenergi eddi was installed nearby for the water heating. Since then, alarms sound at infrequent times, but often enough to be really annoying for the customer.

Unknown switch Discussion ThreadUnknown switch Electrical Advice

Does anyone know this switch?
It was used in the 1960s by my father to distribute power to either one or two lamps. In one position, one lamp would burn at full intensity, in the other two at half intensity.
I am interested in the name of the switch and what it was originally used for.
