I have a circuit in my house that has no power. This is a 20 year old house. Suddenly, there was no power to the outlets and lights in the master bedroom. An electrician came out and says that I have a break in my neutral/white wire somewhere between the breaker and the outlet. I understand that, but he also says that the main hot/black wire reads 3 ohms without power and needs to be replaced. I am having trouble understanding the black wire issue. Could the break in the white wire be causing the black wire issue. He is scheduled to come back and start opening walls.
