Locking Isolator switches

[Petermc]

Hi

I work for a Housing Association. We generally have isolator switches fitted between the electricity meter and CCU's in our flats and the isolators are often contained in a common services cupboard that tenants have access to. We often experience cases of abuse where residents turn off adjoining residents power supply at the isolator. Would we be allowed to lock the isolators in the "ON" position? I noticed that the isolator switched have holes through the switch cover that appears to be for locking off, probably when technicians are working on the system. If so can some form of device be purchased for this purpose?

Thanks for your help.

Regards

Peter

You should NEVER lock an isolator in the on position as what would happen if it needed to be switched off in an emergency and the keys are not available

Welcome to the forum...

There most certainly are numerous devices for locking a switch / isolator OFF for safe maintenance work...

But I would be extremely hesitant about locking any isolator ON!

not a good idea IMHO.

Either the isolator needs to be there or it doesn't?

If yes.. it should be kept functional and available for anyone to disconnect the supply in an emergency

If no... remove, or reposition it where it cannot be tampered with by unauthorised persons.

Maybe an alternative solution such as CCTV monitoring the cupboard and fines & penalties for persons tampering with other properties supplies?
