Testing
Upon correct installation and connection to an electrical supply, the equipment can be tested in
order to ensure its’ correct performance. A competent person with some knowledge of electrical
equipment must carry out this work.
Equipment required:
Multi-meter with leads
Ammeter
Using the equation P=VI, the approximate power output of the equipment can be calculated in the
following way:
-
Using the multi-meter, take a voltage reading;
-
Using the ammeter, take an amps reading from the live cable to the lamp;
-
Multiply these figures together to give an approximate wattage (Power output).
For example:
Using a 240v 1000w Tungsten halogen lamp:
Voltage reading = 240v; Amps reading = 4 amps
Therefore, Wattage = 240 x 4 = 960 watts
