I don't think that i have ever seen this question asked before, so here goes. When you get a call for a elborate display, do you ask the homeowner about their house wiring? If the each outdoor outlets are on separate circuits, with no other outlets attached to that circuit? Do you check or take the customers word? I know that i wouldn't be able to sleep at night if I wasn't sure things were safe. I don't do any lighting but have done quite elborate displays for my parents home years ago. For them I had to install several new circuits and many out door outlets to keep from burning down the house. Just curious how you guys go about this.
