![]() Not to sound sarcastic or rude, but I have degrees in electrical engineering and computer control systems. You remember as a kid when your mother ran the vacuum cleaner and the television produced snow? It is an AC MOTOR and AC MOTORS should never be attached to any device that is supposed to ‘massage’ or otherwise ‘level’ electricity for computer components. If you try to treat it as nothing but a huge battery, you will run into problems.įor instance, a fan should never be plugged into a UPS. The point I am trying to make here is that a UPS is a highly specialized power source for computers. I have had a perfectly good UPS (checked by manufacturer tech) trip because of a laser printer. I’m hoping so, because I have an unmarked extension cord in my laptop case which I occasionally use, but never for more than an hour or two at a time. I suppose you could use a 16 AWG extension cord on a temporary basis (say 1 or 2 hours at a time), but not longer than that. I’ve always just looked at the cord, and if it looks thick enough, I use it. That’s a legal term.Īll the ones listed on the PC Cables page are 16 AWG. PCCables’ “Heavy Duty 16 Awg Wire” is puffery. This applies in the USA, I don’t know elsewhere. Common household extension cords (zip cord) are 18 or 16 AWG. Pay the money, it’s worth it.ĪWG is American Wire Gauge the smaller the number, the bigger the wire. ![]() You can find power taps that have 14 AWG cords, although you’ll have to hunt for them too. The size is commonly marked on round cords, although you may have to hunt for it. Whether it’s a power strip (tap) or otherwise, your electrical cord should be at least 14 AWG. It is not worth the extra cost to using a surge protector on UPS, before UPS or after UPS. In this sense, surge protector does not affect UPS. The voltage limit that triggers the device is from 400V-600V. The device has to be very fast, else it is not effective. Peak voltage is the one does the real damage. Because the surge is a very narrow pulse and fast, surge device is able to absorb the excess energy portion. The total energy is the area of the triangle wave. It actually decays very very fast as well. The electrical surge pulse is like a right angled triangle wave super fast rising edge, then slowly falls, comparatively. If energy rating is low then speed is moot. The other limit is speed, in nanoseconds (ns). Most surge protectors list their energy absorption ratings. Get spike hits, then energy accumulates until it reaches the limit. Overloading it and it’ll burn open (never shorted). Surge protection is by a solid state device.Īt certain peak voltage level it latches on, bleeding excess energy away (actually shorts the AC line, temporarily).
