I am an apprentice electrician. I only have 1 1/2 years experience in new residential contruction. I live with my parents. They have a problem. Lights flicker and sometimes power is lost to some things but not others. No circuit breakers are ever tripped. The power comes on to whatever is affected usually within 10-15 minutes. More than one circuit is affected by this. I replaced their old Zinsco circuit breaker box because I've read that this could be a source of the problem and sice I've read where they are a fire hazard anyway so I thought it would be the first place to start. Although the house is old and has the main breaker located outside the house. I did not replace that. Any ideas where to start? Undervoltage problem from the power company?
