You missed my entire point. Those UPS's still have 20 cent capacitors in them that blow when they've reached a surge load limit. Operating one on an ungrounded (which is what the OP stated) outlet will hasten its demise. Of course it'll protect your equipment, but you'll be buying new ones every six months because you still have no neutral on your circuit. |
Again, running 10-2 and hanging 15 amp outlets on the wire?
You can't use the backwire slots, (Which I wouldn't recommend anyhow,)
and you will have trouble physically putting that wire under the screw.
So, what's the point? And the cost is NOT insignificant. 10-2 approaches double in price to 14-2, which is what you would HAVE to use, minimum, for a 15 amp circuit. And I'm a bit fuzzy on the "breakers inside them." Do you mean Ground fault receptacles? Here's a shocker for you......you can make a ground fault outlet work, even in an outlet without a ground wire.
So that's no safety factor in this situation. In fact, that could bite you in the ass on a fault. If you had a surge, that tripped the ground fault, it's possible that power would have nowhere to go for a split second as the neutral snapped off. Bad news for the next best grounded thing close to the hot wire.
(Extreme example)
Now, your talk about the UPS is Simply wrong. A proper UPS Does NOT use a 20 cent cap. a Proper UPS line conditioner ISOLATES the output power through a transformer, and modulating circuit. There is NO physical electrical connection between your equipment, and the wall power. There is an air gap in the power transformer isolating it. The circuit then monitors and shunts the excess power, using the batteries as a part of the circuit, as well as many caps, voltage regulator, and assorted other components. Your statement regarding failure causes is completely wrong, and I would challenge you to find any support for that, even in theory. The weak part of a UPS is always the batteries, which have X life span, regardless. Theoretically, a bad AC power supply system, that would draw/charge cycle the batteries regularly would actually improve their life span. It simply the battery life cycle works. The bad thing is keeping the batteries peak charged endlessly. (Again, a better UPS that "conditions" the batteries would be an improvement)
Wanna see a schematic?
This is unlike a "surge protector strip," which still has a physical hard wire to hard wire connection from equipment to the wall. The cap in there is used merely as a tiny little dump reservoir for slight over/under power surges. Really, quite useless, considering how much faith people put in them.
A UPS is just a no brainer, if you make your living from that equipment. A very inexpensive insurance policy. More so from the power management, rather than the "hours of backup" specifications of the UPS.
