This house has 3-phase power.
A while ago, two of the five spot lights in the bathroom stopped
working. They used 12 V light bulbs. I removed the two transformers and
replaced the two light bulbs with 220 V ones. They work now, three 12 V
and two 220 V bulbs. However, the lights in the walking closet stopped
working. I checked the voltage at the switch. It's 386 V.
What did I do wrong?
