And for the negligible difference in cost, it's better to over-wire than under.

Depends on how old the wiring is.

You do realize that a UPS system will still be vulnerable and is likely to blow on an ungrounded supply line? Using a UPS as a solution here is throwing away money, IMNSHO.

Frankly, it's worth running the new line anyway.By the time you get done replacing 4-5 UPS's and/or surge suppressors, you'll be sick of the aggravation and you'll be out all that extra money, and still won't have clean power.

With no ground, even the tiniest fluctuations become as bad as major electrical storms.

Pay now, or pay later....

I reckon we may as well argue about this as anything else.....

While you're running that 10-2?
What's the plan? 20 amp breaker? 30 amp breaker?
What about the outlets themselves?
Planning on passing an inspection at any point?
Or heavens forbid you have a fire, and the fire inspector, insurance adjuster sees a recent change, with a 30 amp breaker, and 15/20 amp outlets that melted and caused the fire?


A proper, isolating UPS will SAVE your PC by isolating the power from the line, and adding/subtracting to give an even 115VAC at all times.
It's the fluctuations that cause the problems....not the redundant ground.
The ground is useless, unless you lose the neutral. Sure, a proper "surge protector" may need to shunt some extra voltage spike to ground, but you're talking about trusting your equipment to a 20 cent capacitor?

No, a proper line conditioning UPS is BY FAR your best choice here.
Not about the battery backup....just about balancing the line.

And even 1-20 amp line will run an awful lot of computer equipment......
