My 6yr son told me to quit this hobby after almost burning down the house.

you're lucky you didn't get electrocuted while putting out the fire with aquarium water since you did have a live wire on the floor sparking. In either case, good thing you were home to catch it. Another 5 minutes or so, you would have lost at least the room.

I'm putting together a tank right now and I'm starting to reinforce my wire routing and connections. We can never be too safe.
 
Hi terryhendrixson, did your insurance cover the damage? Can you me more about arc fault breaker? Is that the samething as commonly called circuit breaker?

Some reading for you re: Arc Fault Breakers

Oh yeah, you can get GFCI breakers, which protect entire wiring circuits in your house, but, since it's for the whole circuit, everything will cut off when the gfci trips (which is should only do if there is trouble anyway OR if it's too sensitive to your MH lights turning on!)

ALso, with GFCI outlets, you can actually protect all the "downstream" outlets with the same GFCI unit, if the GFCI unit is the first outlet in string of outlets wired in series.

Arc fault breakers will not detect arcing from the ballast to the lights. The arc fault breakers will only detect arcing that occurs directly on the 120V line.
There are two parts to the ballast: the high voltage side (the side that plugs into the wall outlet/120V) and the low voltage side (the side that plugs into the lights). The low voltage side is typically around 30V. So if the low voltage side shorts or begins to arc, the arc fault breakers will not notice it. This is because the ballast acts like an isolation unit between the two. It takes 120V in and steps it down to 30 volts.
If the arc breaker where to notice the arcing on the low side, then it would trip all the time because halide bulbs and flourescent lights create arcs when turned on.
 
That's right. It's seems like a good item now to install smoke alarms in our fish rooms after what happened to both of us. It might be a good idea for everyone to add: inspect tank equipment to their spring cleaning list.
