Obsolete Devices: VOELCB Operation and Problems
Theory of operation and various problems encountered with voltage operated earth leakage circuit breakers.
These voltage operated devices have not been used in the UK for over 30 years, they are not manufactured any more, and all of them should have been replaced decades ago.
Unfortunately, there are plenty of buildings which still have them.
The replacement for one of these old VOELCBs would be an RCD - a current operated device which works in a totally different way.
