Switching between phases depending on live health Discussion ThreadSwitching between phases depending on live health Electrical Advice

Hello, I'm pretty new to the forum. Hopefully, this is the best place to post it somehow.

Currently, I have a setup of a distribution box, which is able to supply 63A three-phase load to an EV charger, running two-phase load of 16A. It demands 3.7kW from each phase, making it a 7.4kW charger effectively. It's connected to the distribution box using a 32A 5P CEE plug.

I'm living in a compound where the line voltages are dramatically changing due to heavy AC/VRF/HVAC usage. When people start running their ACs, one phase the other would drop more than the others, making the voltages in three phases imbalanced.

Since my charger is using two phases only, I'd like to have rotating three way switch to switch between the lines.

• There will be three combinations, L1L2, L3L1 and L2L3.
• The circuit won't be live while doing the switch as I'll switch off the breaker.
• I don't think the device is looking for the order of the phases, however it would be great if we can have that.

I've been considering this for while, I don't know if there is a special device for that reason, but I thought a setup with using multiple contactors may work, however it would be costly.

This installation is done in Turkey, but I'm living in England and I'll order the required parts here.

Any suggestions?
