240 V TEST

The 240V Test checks boilers for mains power supply to the boiler terminal strip.

Mains voltage and polarity tests

This test will ascertain the correct polarity between L and N although, some boilers will operate unaffected by reversed polarity. Connect boiler to power supply via 3 pin…

Resistance to Earth

Resistance to earth: (dead test) This test confirms the integrity (resistance) of the insulation between L (Live) and E (Earth) on the boiler terminal strip or plug top…

Short Circuit

Short circuit: (dead test) This test will ascertain the integrity of the internal resistance of the boiler and should read no resistance/infinity between L and N on the…

The Earth Continuity Test will ascertain whether the earth continuity between the earth supply to the boiler and the internal component earth connections and the metal casing of the boiler is earthed correctly.

Mains Voltage Test

Mains voltage test: (dead test) This test isolates the power supply serving the boiler, so as safe, further testing can be continued, without the risk from stray electrical…
