LIGHTING CIRCUIT TESTS – ONE WAY AND TWO WAY – 3 PLATE METHOD – EASY AND ACCURATE FOR BEST RESULTS

This video looks at resistance tests on lighting circuits. Focusing on 1 way and 2 way lighting with a 3 plate system, it is easy to adapt for use on a 2 plate system.

Following the guided steps and understanding the testing shown, and using this method, will give the operative the confidence that they are testing correctly and give them advanced knowledge of what the R1+R2 test results should be. How to recognise wrong numbers and what to do about them.

Some frequent and recent questions have asked things like …

What resistance readings should I expect with a lighting circuit?

How can I calculate R1+R2 and know that my measurement is correct?

Every lighting circuit that I work on is different, how do I know if the test results are right or wrong?

And what am I actually measuring, which wires are under test? How can I tell?

To help us to understand where the resistance readings come from, we break down each circuit, two way and three way and follow the path of the electrical test current from the meter.

The method used will elevate your learning to a much higher level and give you much more confidence on site and in assessments.
