Was fixing a bad wiring job between a sub panel and a 240v 2 phase water pump and noticed that my multimedia was only testing it as 190v. Checked back at the breaker and saw the same. Checked between L1 and L2 on a different breaker and saw the same.
My 240v equipment (dryer, oven, water heater, 2 HVAC units) all work fine.
Should I be concerned?
How big of a deal is this? Like call an electrician asap or wait until I have some other electrical work lined up?
Here in the Netherlands you can get 380V power using the same technique. Very useful for powering an induction stove, or if you want faster charging for your EV
Edit: Referring to three phase power, not two phase power. That is why we get 380V and not 460V
