ELCB tripping

[Aidan1]

Installed new power shower in Jul 04. Has worked well for the last 10 months but over the last month the ELCB was tripping out when the shower was running. Now it is at te stage where the ELCB trips as soon as the shower is turned on. This pulls down all the sockets in the house. The shower switch is still lit and the main circuit breaker is also staying on. I checked the shower and all the wires seem in good shape. Not sure why the ELCB is being pulled down as the shower and Sockets are on 2 seperate circuits.

What does the ELCB protect exactly?

is this really an ELCB e.g. a device with two earth terminals or did you mean a rcd

Voltage operated ELCBs were removed from the regulations in 1981, however current operated ELCBs are still around today.
Hope this sheds light on the subject, see 2.1:

Thats what prompted me to ask what exactly the device protects.

The ELCB is linked into all the sockets circuits.
Turns out the some of the insulation on the pump motor windings had broken down. took the service guy a new element, and stat before he found out.
