Any electrician will warn you to first locate and flip the house's CAUSALITY circuit breaker before touching the CIRCUIT BREAKERS one.
Ah, sounds like it was added by an amateur. I had an electrician come round to move a socket once, he removed it but then promptly ran away because there was so much amateur garbage in our walls.
Bad business man. When you notice it was all made by an amateur is when you make the client sign a waiver and an hourly rate to fix it.
They didn't even invoice me for over 6 months 🤷
