Power Question

Ok this is actually 2 questions.
1. I was looking at the Furman Power Conditioners. I was interested in this www.guitarcenter.com/shop...l_sku=103365284
Is this worth it, or will any Surge Suppressor from Home Depot do the same??
2. The new article on the home page concerning power was a little helpful, but is there a simple way to figure out how many amps, mixers, etc. that I can plug into a 15amp outlet and get away with it??

On each piece of equipment there should be a nameplate or sticker that gives the operating voltage, freq or Hz, amps, and watts. The wattage on that sticker is NOT the output wattage, but the watts that unit consumes.
A 15A power circuit is capable of handling 1800 Watts, but I usually limit myself to 1600 Watts per circuit for safety and fudge factor.
Simply add up the watts of the seperate units until you get between 1600 and 1800. That is the limit on a 15A breaker.
You can also figure it using the amp ratings on the units, if it lists amps. Just add amps until you get 12 or 13 amps and there you go.
As far as the Furman power conditioner goes, it is not a true conditioner. It is a surge supressor and RFI/EMF filter. True conditioners have isolation transformers for true high voltage protection, and solid state crowbar circuitry instead of MOVs to limit the overvoltages and boost the brown outs. The Furman you referenced has neither of those. It is a much higher quality surge strip than the Home depot ones, but not a true conditioner. The giveaway is the use of the Metal Oxide Varistor (MOV) for surges. This is a cheap, one usage device about the size of a quarter soldered between the hot and neutral. If it gets a surge, it will typically burn out and NOT stop the power flow. You have no idea it is not working anymore.
The best power conditioners are made by APC. (American Power Conditioners)

Aug 20, 2007 12:03 am All about placing your bets. Home depot will do little more than your home circuit breaker. Furman is per above much, much better. APC is no doubt the cat's butt. Like any insurance policy the price goes up linear to the protection. I have a furrman and have suffered no power issues for the last seven years. I am getting to the point of putting in an APC for the computer. This move for me is more protection of data than equiptment damage e.g. severe brown outs our stopages between saves. Lightning is the complete booger outside of all policies. I have seen lightning take out equipment in rooms connected to nothing, neither power or other equipment. I was given a mixer that suffered such a strike in a garage. The entire garage was ionized and cooked most every mosfet in the device. It just happened to be the path of colectively least resistance to the intricate nature of that power flow in that instant.
