You could install your electric dryer on a surge protector with a voltage capacity of 120, but you would not be providing sufficient protection. As it stands, most clothes dryers are 240 volts and most surge protector components (MOVs) can only withstand 120VAC surges. The standard American home uses 120-volt systems, so most surge protectors are made for the 120 volt capacity, meaning there isn’t an outlet surge protector made to carry the burden of protecting a dryer rated for 240VAC. Does your washer/dryer need surge protector units to protect it? The answer is yes. The only problem is the lack of devices made for these specific appliances. However, there is another option for preventing a clothes dryer surge: whole house surge protectors.
A whole house surge protector connects to either your home breaker box or at the meter. If you want to connect one at the meter side, you will have to call your power company and set a time for them to come out and connect you. This surge protection service is usually provided with a small fee attached, typically about $5 per month. Well worth it if you want to protect your dryer. As you won’t readily find a 240volt surge protector, a house surge protector is the way to go.
Electrical surges are unpredictable so they can strike anytime. This means that you can’t prevent power surges to clothes dryer units either. They happen when transient voltage peaks above normal levels (120 volts). The duration of the peak may last as short as half an AC cycle or they can last for several seconds above twice the normal level. When they pass through your lines and enter your electronic equipment, some components are too sensitive to withstand the surge. When this happens, the electrical surge can permanently short your system. While you can protect some equipment with a standard wall surge protector, some high-energy appliances like air conditioners and clothes dryers require powerful protection provided only by surge protector whole house installation, as surges that would be sufficient enough to damage these large machines would most likely originate externally.
It’s easy to understand the benefit of using a washer / dryer surge protector. An external surge would be powerful enough to melt the insulation within the wiring of your electrical lines and leave your equipment vulnerable. Whole surge protection would prevent this and add a secondary layer of protection to devices already installed on point-of-use surge protectors. At the point of entry the surge is “clamped” by the whole house power surge protector and diverts the excessive current to a grounding area where the surge dissipates.
As for a whole house surge protector review, the best device for your money will have multiple surge protection components within it. One component would be a MOV. MOVs (metal oxide varistors) defend against low voltage surges. This is important as even the smallest surge can damage your equipment’s microprocessors. Another feature to look for is an LED indicator. This lets you know that your device is protecting you as it should. When the light goes off, you should replace your surge protection device.
When it comes to using a surge protector, washer dryer units would definitely benefit. Here are some manufacturers of note to look for in your search:
Look to any of these companies for surge protectors for the whole house and help yourself find proper dryer surge protection.
