Hi All,
There seems to be some debate, at my shop any way, about where and when SPD's are required. Take the following questions... How many SPD's would be required on a New Service on Existing SFD that has an 80A Sub- Panel (Sub- Panel is also new and in the basement)? Then the same question when the New Sub is in a detached garage. Finally, when the New Sub is in a Detached ADU?
