Electrical Question. Consumer Unit.

Zoomup
Evenin' All,

                       it was fun getting to work today. Firstly, I had left my van's windows open about 5mm at the top to reduce condensation buildup. A Big mistake. The dusty fine snow had found a way in and covered the driver's seat and the steering column and some parts of the dashboard. Joy and bliss I said.


Anyway now to the question. Sparky Sid was installing a new Niglon R.C.B.O. populated consumer unit. It has a main D.P. switch and six R.C.B.O.s.


He always uses one  short length of P.V.C. earth sleeving when assembling these types of consumer units.


Why?

    perhaps like a ordinary dentist, but he stands on an upturned  plastic beer crate?


    Years ago I was involved in a scheme to make heart monitors and other medical sensing  kit  work better along side an electric scalpel - not this exact model, shown cutting meat, not a patient in this video  and actually the whole tool set for working on a semi-live patient (electrically live- , they should also be fully live in other sense as well ) has to be modified so that there are not shock hazards and equipment malfunctions in strange places, so they probably do make insulated kit for patient use as well. I understand it has all by and large been solved now, but at the time it was very interesting, though not totally compatible with my being squeamish. Just the problems of diverted current again but in another medium.

    Mike.
