Will APC UPS work without ground?

Does a UPS have a grounding wire?

1 Answer. While a UPS, and many surge protectors as well, will show wiring faults equivalent to a magic 8-ball, a UPS should never actually use ground, except if there is a true fault. A brownout or blackout should trigger the USP battery/inverter but not actually put any current on the ground wire.

What happens if you don’t have a good ground?

If your outlets and electrical box are not properly grounded, appliances and electronics you are using could end up passing excess current through you, using your body as a means to complete the path to the negatively charged ground. In other words, you could be shocked or electrocuted.

Do UPS work on ungrounded outlets?

Aaron, the answer is Yes, BUT the built-in surge protection in almost all UPS units will not work, as they all work by shunting electrical surges to ground (and you apparently don’t have an earth ground).

What do you do if there is no ground wire?

If you don’t have a wire coming in to hook your ground to, what you do is you take your ground wire which is either a solid copper or a green wire, you’ll take that ground wire and you wrap it around the ground screw. Then, you’ll just tighten up that screw and then you’ll hook up your black wire and your white wire.

Why is UPS voltage neutral to earth?

Sometimes or many plants, the neutral is also earthed. Hence, that earth is being brought to the UPS panel and hence the UPS earthing/grounding is very important. The analog control and regulatory circuits will not function properly without the reference.
