I agree with that Mindy. Experienced the difference when when having work done on my place and also from working with many tradesmen in my Inco career. However that applies to all the trade.

Rehash; :lol:

My tank runs on a separate 15 amp circuit, installed just for it, with a GRI outlet in the wall. My controller, which runs the lights, heater, return pump, skimmer, reactor, and top off all runs from it.

Another room receptacle, which is on another 15 amp, but room circuit and has an Arc fault/ GFI breaker, runs my two MP 20,s, plus another in tank heater if we are away.

A GFI is firstly a personal protection device. It is designed so that a if a person completed a ground fault (short to ground) the GFI would trip so fast that the person would sustain no injury. A GFI is designed to trip with 5mA of stray electricity in less than 25ms.

Having said that many fires can start as a gound fault (short to ground). A GFI would help in preventing these fires. Remember that electicity can easily stray to ground in many many ways. If you have have every been shocked it is most likely that the electricity passed though you to ground....even though you may have been standing on wood floors or carpet. If you were not grounded you would be isolated and in that case you would not feel a shock at all.

Where abouts in Edmonton can you find these for $10? I checked Home Depot and they were on sale for $59. Thanks!

two pack for $30 HD

could see $59 maybe for a GFI breaker

I'll have to try a different HD then. The only one they had in Sherwood Park was a single plug in model with a 1 meter cord. A 2 pack would be exactly what I need, maybe the new one on 17 St. will have them. Thanks Mark.:smile:
