I bought a new surge protector and the included specification material says I need 30 feet between the outlet and the service panel. My situation is probably about 5 feet. The outlet I want to protect is on the first floor and almost directly over the service panel in the basement. The surge protector itself has a 6-foot cord.
Can I add a heavy gauge grounded extension cord (let’s say 25 feet of the same gauge as the house wiring) to satisfy this requirement?
