## MainsBreakOutBox
13A socket break out box with 4mm jacks to measure voltage and / or load current and earth leakage current.
Intended as a simple example of NopSCADlib use. Don't build it unless you understand the safety implications of working with mains electricity. In the words of
the great [Paul Carlson](https://www.youtube.com/channel/UCU9SoQxJewrWb_3GxeteQPA), "if you are following along, you are doing so at your own risk".
In normal use the neutral jack sockets are linked with a short lead and so are the two earth jacks. Current can be safely measured using a clamp ammeter around the neutral link.
Voltage and current waveforms can be measured simultaneously with a [Mooshimeter](https://moosh.im/) CAT III multimeter connected to the bottom three jacks.
Earth leakage current can be measured by connecting an AC milliampere meter between the two earth jacks. The DUT must be mounted on an insulated substrate and must not be touched
while its earth is disconnected. Don't be tempted to float the earth of an oscilloscope this way, use a mains isolation transformer to power the DUT instead.
Earth leakage can be measured Canadian CSA style by disconnected the neutral link from the left socket and linking the central neutral to the live.
