[QUOTE="wbvs58, post: 1836756, member: 16453"] That tester will only check your power source and extension lead I think, the multimeter from the trough to the ground would be the go however if your power source is wired correctly with a safety switch back at the switch board if there was a stray current it would trip the switch no matter how small. You can only have one earth stake usually back at the switchboard, the earth is linked to the neutral back at the switch board (Neutral Earth Link). Does the heater run directly off your power supply or does it have an isolating step down transformer to run the heater, if this is the case then any problem would be in the heater and this would isolate it from your power supply and not trip the safety switch. If in doubt get a Sparky to check your setup. Ken [/QUOTE]
