are surge protectors necessary for ac units?

An HVAC surge protector is installed within your HVAC unit or near it to act as a buffer between the machine that keeps your home comfortable and any unpredictable power surges. Even small surges can cause irreversible damage.

GFCI Protection The NEC requires GFCI (ground-fault circuit interrupter) protection for all standard receptacles serving laundry areas. This includes the 20-amp designated receptacle for the washer (and gas dryer, as applicable) and any general-use receptacles.

Cruise ships recently implemented rules against surge protectors because they can cause problems with the onboard electrical system. You can find the General Electric outlet tap shown above on Amazon. You can also find power strips there as well.

All surge protectors are not created equal. In fact, there is a tremendous range in both performance and price of protection systems. At one end, you have your basic $5 surge protector power strip, which will offer very little protection.

As it's already well known, dwelling units currently require AFCI protection. Now the 2017 NEC is expanding protection to guest rooms and dormitory bathrooms and circuits supplying outlets and devices. The 2014 requirement is that a 125 V 15 A or 20A receptacle has to be located within 50 feet.

Per 210.8, you must install GFCI protection for all 15A and 20A, 125V receptacles located in bathrooms, rooftops, and kitchens in commercial/industrial facilities. However, GFCI protection is not required for receptacles installed outside a commercial or industrial occupancy.

No AFCI or GFCI Option Tandem circuit breakers are not an option in these circumstances. Also, when an electrician makes repairs or upgrades to an existing electrical system, he is required by law to install whatever AFCI and GFCI protection is required by current code.

If you are looking for the best overall, I recommend the APC P11VT3 because it features 11 outlets with a surge energy rating of 3020 Joules, accommodates a range of plug sizes and offers an equipment protection policy. The component that is most vulnerable when it comes to power surges is the microprocessor.

In order for the surge protector to work properly, it must be connected to a grounded outlet. The same is true for most all UPS (Uninteruptible Power Source) backup systems.

Even if you live in the desert, your A/C or refrigerator could kick power spikes back down the lines to your A/V gear. Since most surge protectors are cheap, they're worth getting (and regularly replacing) just in case.

Yes a disconnect is needed if it is not within site of the breaker box. The easiest way I could think of is to use two A/C disconnect boxes, one for each circuit. Yes you will need secondary disconnects even if the panel is within sight if you do not have a main disconnect (i.e. split bus).

Yes, a surge protector isn't designed to last forever and will eventually wear out. The bad news is that it's almost impossible to tell when a surge protector wears out. Which means, you might think your appliances are protected against dangerous power surges when they really aren't.

An AC cover might seem like an excellent protective measure, but the fact of the matter is that it could cause more harm than good. For one, a cover simply won't protect your air-conditioning unit from moisture, which builds up naturally due to humidity and can trigger the growth of mold.

Most of us have more devices than we have plugs in the wall, which is why you'll likely find a surge protector behind most people's televisions and under our desks. However, not all surge protectors are alike, and some even put your gadgets at risk.

Outdoor outlets have watertight covers that allow them to stay covered even with a cord plugged in. The National Electrical Code requires the use of ground fault circuit interrupter (GFCI) outlets outdoors. ... As with all electrical projects, check local codes before doing any electrical work to ensure compliance.

Standard electrical outlets don't have any protection against power surges and spikes. Surge protectors are generally made and sold in the form of power strips, although you can also buy single-outlet surge protectors that sit against the socket and provide a single, protected outlet.

A surge protector or surge suppressor is an appliance or device designed to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or shorting to ground any unwanted voltages above a safe threshold.
