Equipotential bonding is often something that can be overlooked and can result in electric shock from potential voltages and unexpected costs if corrective work is required after installation. AS3000:2007 states that any conductive material within 1250mm from the pool edge will require Equipotential bonding.
To overcome this issue, we have researched and developed a spigot insulator which will provide a non-conductive barrier between the spigot “metal” and the pool.
The tests carried out with a insulator tester FLUKE 16502C Multifunction Tester showed the metal is fully insulated to touch.
What is an insulator tester? An insulator tester is a device which provides a high voltage current for testing non-conductive membranes, coatings and linings over conductive materials.
Step 1 – reading taken of an exposed spigot to observe a “loop” or circuit being created by the testing device. 1000 volts is applied to the metal spigot base through the green connector on the tester. The red connector on the tester takes a reading of volts received. The reading of 0.0 showed that a “loop” or circuit had been created.
Step 2 – Take a second reading with the insulator sleeved over the top of the spigot. The reading of 1000 showed that the “loop” or circuit had been completely blocked by the spigot insulator.
