Electrical Question. Consumer Unit.

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?

  • Ah, some good suggestions there. Now for clues.


    a, No C.P.C. is involved.


    b, The short length of earth sleeving is less than 50mm long. Perhaps 4mm diameter.


    c. The use is purely mechanical.
