While I embrace both the inner Tim the tool man Taylor from Home Improvement as well as Clark Griswold with all my Christmas lights in my yard it seems that fifteen amp service I have on the circuit that contains both my basement lights AND the outside power outlets won't support both. It's maxed out. In my old house, I had 20 Amp service on each individual outdoor breaker which was a investment I made when I built my last home. This one? Try kicking on a shop vac and everything goes out.
