Our company is southern electricity but another company wants to do polarity tests free. What is a polarity test ?
Answers
A polarity test will confirm that the supply cables are the right way round at your service head (usually by the meter) i.e.line 1 is line 1....line 2 is line 2.....line 3 is line 3 and neutral is neutral. This test will be carried out after any work has been done on the grid supply system.
