When aluminum wire joins to the copper of fixtures, it corrodes and the connections loosen.
Aim for “home runs” for key areas and appliances—these are when a wire runs directly from a circuit breaker to an outlet, with no other devices on that breaker.
That can reduce loads on the power system and keep popped breakers to a minimum.
Working in older buildings is a complex, demanding, and difficult process.8.
Make demolition and reconstruction an integral part of the job.
The loose connections increase resistance and create heat, causing a fire danger.
