Electricity on the geyser
An installer should always take precautions when working with electricity. The most important precautions
to perform
before
doing maintenance on a geyser are:
Test with a MULTIMETER
to ensure that
there is no current on the wires. IMPORTANT
Make sure that there is no reading on the
multimeter.
Switch off the circuit breaker
of the geyser
at the main DB. This is done to ensure that
there is no power supply to the geyser
Switch off the isolator switch in the roof.
The isolator switch acts as a switch to isolate
both the live an neutral from the main supply
should someone accidentally switch on the
main supply or the circuit breaker fails
