The brand-new roommate and I are installing ACs in our rooms come fight off the brand-new England summer. He claims his uncle (who offered us the units) specifically claimed not to plug them right into surge protectors. I'm not engineer sufficient to understand why this would be an issue...any explanations the end there? Google has been how amazing unhelpful. Additionally the entirety thing has actually made me realize I know shockingly tiny about how house electricity and also surge protectors work. Please educate me while i drink this 'gansett.

It probably has to do through the breaker top top the rise protector. Air conditioners have a considerable surge that inrush existing to start up the compressor. This may exceed the setpoint ~ above the breaker, yet it's okay since it's because that a very brief period. The breaker ~ above the surging protector may act too quickly, and also pop prior to the wait conditioner is up and also running.


Yep, same factor why girlfriend shouldn't plug a kettle right into a surge safeguarded powerboard either. Exact same issue.


The only thing I can think the is the rise of the ac kicking in will expedition the surge protector. Battery earlier up solution will gain fried through something favor that plugged in but that's a whole various story. Ns can't think that a factor why a surge protector would break, or her ac would certainly break if it's rated for a high enough amperage to cover the ac unit.


This is an ext or much less right. The initial present draw native the compressor/fan turning on is nice substantial; that drops turn off shortly.

However, there room different varieties of fuses. Most surge protectors usage fast-blow fuses, which will trip an extremely quickly ~ detecting a too-high current. The home circuit breakers, top top the other hand, are much more robust and akin to slow-blow or time-lag fuses - they deserve to handle an overcurrent for a short amount that time prior to tripping.


Awesome...looks favor a agreement has built. Sounds like the uncle may have actually been overstating the dangers, yet he's not completely crazy. beer-selection.com is awesome.


many ACs draw virtually 15A that current, i m sorry is the best rating that a typical household wall surface outlet (and the rating of many surge protectors) The advice is more than likely meant to save you indigenous overloading the wiring.


Two reasons:

Plugging it right into a rise protector invites other things to be plugged into that rise protector, perhaps damaging those tools from the engine cycling. The AC need to be on it's own devoted circuit together well.

It will damage the resistors in the surging protector, ultimately killing the protector as the AC cycles.

AC compressors really don't need surge protection, they room surgey by nature. The thermostat must be robust in style to resist being on the very same circuit as the AC unit, perhaps incorporating the exact same circuitry as a rise protector (resistors that boost in resistance as voltage goes over a details point, usually roughly 400v IIRC).

I would certainly recommend making use of a 12 gauge extension cord, they offer these in quick lengths particularly for this purpose. If girlfriend don't know the layout of the circuits in her home, usage a lamp to recognize which circuit a provided outlet is on. Try to isolate the AC and also fridge ~ above their own circuits if you worth your electronics. The fridge deserve to share with various other motor pushed appliances as lengthy as girlfriend aren't exceeding the circuits capacity. The AC will likely need come be all by itself, or possibly one tiny motor driven or resistive device like a toaster oven.
