Is there a safe, long term way to monitor actual voltage going through an outlet? I can check with a voltmeter, but it would be ideal to have an ongoing display -- even better to collect historical timestamped data.
We have kilns in the garage, all wiring has been done professionally and to code. Recently both kilns are not firing to temperature and one of the troubleshooting steps is checking the voltage while running. We might not be getting the needed voltage during peek times.
I'd like to have a continuous read-out of the live voltage if possible. It seems like it would be possible to have a device that is plugged into the outlet and the kiln plugs into it, but I'm not sure if something like this exists.
I'm also in contact with both the city (municipal power) and our electrician.
