RCDs MAN they are important!! ⚡WK8

This week I looked at tests around making sure the earth path on an electrical system is up to scratch. The earth path is needed to overload a fuse or breaker or to trip an RCD in the event of a fault on an electrical system. As with most things there are test procedures and standards of the electrical system to be met. Thank goodness!!! .... The only problem is I have to learn and remember them all.

Keep learning ...
