A quick residence electrical repair to replace three SPST switches showing signs of toggle arm cracking and separation. Guessing bath cleaning products degrade the plastic as other switches throughout the house do not show cracks (yet). Original part time in use = 12 months. About $3 and 1 hour (travel, purchase parts, return, and install) completes this weekend project. #DIY #Electrician #SafetyFirst

Legrand electrical switches showing signs of toggle arm plastic delimitation and cracking (middle switch has a large chunk already missing).

Also, it might not count as an electrical device in its own right, so maybe the rules don't apply. It does have a built-in power distribution strip, though (in one of the parts) - that was grounded via a wire to a (painted) spade terminal. Any #NZ #electrician care to comment? Should I be installing earthing cables between the components? Sanding/grinding patches and soldering or screwing cables to them?

Just realized when the #electrician installed our new panel, the first thing the grounding line is firmly connected to is a completely isolated stretch of metal pipe. So if something goes terribly wrong in a few places, we could theoretically end up with a 200 amp kitchen sink faucet. Lovely.

A braided copper wire from the electrical panel clamped to two metal pipes before continuing to the front of the house. The metal pipes are attached to plastic piping on one side and go up into the wooden framing on the other, neither of which conduct electricity.
