Pin for a new C.U.

Jaymack

Had a telephone call last Friday after 5pm; the caller said that an electrician, who had now left after installing a new c.u., had installed a "pin" and he had no power in the house. I said that he should contact the electrician; he said that he would get someone else and rung off.

I didn't want to get involved at that time of day but thought about it afterwards; I vaguely remember a few years ago, that a forum member had referred to fitting such an "electronic key", to ensure payment was made for work; anyone know of this "coded switch"; would it be lawful?, would the registering schemes condone leaving a consumer with no electric power?

    This has been discussed before. A forum member suggested that a radio controlled device that would be remotely controlled, could connect N to E (or even L to E via a suitable resistor) so that an R.C.D. would disconnect a circuit or several circuits. This is not legal at all.

    Did you understand this to mean PIN, like Personal Identification Number or a pin like some mechanical device, a small pintle?

    I'm not sure that a keyswitch or lock-off  of any kind would be a sensible thing to install without the customer's permission, and in many ways walking off with the  main fuse or some other vital part would be more effective, though equally of doubtful legality.

    Presumably then this is a customer, or perhaps an end user of someone else's property, who cannot be trusted.

    There are time clocks sometimes used to turn things off when a service is due but they can be more trouble than they are worth unless it takes the form of a reminder that can then be overridden.

    Could the main switch have been left locked off?

    That was my first thought when considering what was said, a "pin-out [or-in] standard" locking-off device, which I've heard described as a "locking pin" or "lockout pin": https://www.screwfix.com/p/mini-circuit-breaker-lockout-system/6514F

    The live testing must have been interesting.

    I wonder if he just forgot to remove a locking-off device at the end of the job (put on when tidying and closing up)?
