Electrical Help!

2521 21
Well, the 2009 season is upon us. It's usually around July that I start thinking about the big day, and this year is no different.

This is a problem, though, that has been plaguing me since H'ween 2008. Last year was our first year in the current house, and we ran into a problem. I'm hoping that someone here will have a relatively simple fix to the challenge at hand.

It seems that all of our outdoor outlets (the garage, the front porch, and the deck in the back yard) are all on the same circuit. Where it gets interesting is if you go to the basement and check out the breaker box - the circuit comes off the box and goes directly into a GCFI, then splits off to the various external outlets.

The result? You guessed it. I can run 4 flood lights and a fogger before tripping the GCFI, and leaving the entire haunt in the dark. This year I've got three 400W foggers, and I have decided that I definitely need more lighting - preferably more task oriented fixtures to focus on individual props.

Does anyone have any creative ideas on how to remedy my dilemma? I don't particularly want to bring an electrician in to wire a dedicated Halloween circuit, but I'm a visual geek and I need my lighting!

Thanks!

I'm assuming that the circuit breaker is a 15A, so yes, you'll be popping it with three foggers and a few lights. I have a similar problem - only two outlets in proximity to the display.
It seems odd that a GFCI would trip on an current demand overload. They're designed to trip on ground faults - inconsistencies in the ground line vs. the "hot" line, such as what happens when you drop the toaster in the bathtub. The actual circuit breaker is supposed to trip when the current demand exceeds it's rating. Are you certain that one of your lights doesn't have a short somewhere in the wiring? The inrush current demand from a fogger when the heater turns on can also cause spiking problems.
You may want to invest $20-$30 in a Kill-A-Watt meter so you can check the wattage draw of your devices. Changing over to LED spot/flood lights will reduce the demand, as well. You can also try using battery-powered LED spots for individual prop lighting.

The two outlets that I use for the display are on individual GFCI outlets. In fact, all the GFCI's in my house are at the actual point of use - none are at the breaker box. I've never seen multiple outlets ganged to a single interrupter. It may be moot, but it seems a shame to kill power to non-faulting outlets.
Perhaps you could have an electrician remove the multi-GFCI from the circuit and replace the outlets with individual GFCI's, but I don't know if that would gain you anything since you would still have three outlets going to a single breaker. The alternative is to cut in new breakers, of course.

I may look at the LED option a little bit. A lot of you seem to have reported success with them, so I'll do some more reading.
For individual prop lighting I use small LED spotlights that I make myself. They use anywhere from 3-5 ultrabrights per spot, and run on 9 volt batteries. There's a number of how-to's on making these. I really like the portability and that they don't need any AC cords. The batteries have lasted for two seasons with no noticeable dimming (~ 40 hrs).
