I'm adding a breaker to hook up to an additional electrical
outlet in my 1997 Scamp
13. So I'll need to thread and clamp electrical
cable through the wall of the breaker box.
The breaker box is plastic. I can feel a circular line on the left underside of the box but it doesn't break out, which ever side I press it from. Do I need to pull the entire breaker box so I can drill or cut a hole?
