It’s always a good idea to test your distro with a meter before use. This ensures it’s safe to use and supplying the power it is rated to supply.
How to Meter a Distro:
* this is based on North American camlock colours. Always check if you’re unsure.
*I am not an electrician. Verify this info. If there is an electrician on site or someone with their LPEC or FE, make sure to shadow them before trying this on your own. You may need your LPEC to do this. Here’s how you can get it:
1) Make sure the meter is in AC not DC
2) Plug the black prong into your ground (green)
3) With the red prong, measure each hot
(black, red, blue)
They should read close to 120v in a 120v distro
4) Then measure the difference between each hot. This means black prong in one hot, red prong in another.
This test should read about 208v between each hot in a 120v/208v distro.
5) Then measure the difference between ground and neutral.
This test should read close to zero or 1v max.
