Power surge protection Thunder Bay ON

Picture
You might be familiar with the point-of-use surge protector that looks like a power strip or even a surge protector outlet to protect your delicate equipment from sudden voltage spikes.  But they don’t really cut it when there’s a higher voltage power surge, so although they provide a good first-line defense in smaller voltage spikes, they may need backup. Here’s where a whole home surge protector comes in handy.  Here are some commonly asked questions by homeowners:

Do whole house surge protectors really work?

Answer: They do, but it depends on how much voltage they let through, specified by the voltage protection rating (VPR).  So if you choose one with a high VPR, it’s great for instances like lightning strikes, downed power lines or large appliances cycling on and off, but they may allow lower voltages through that can damage sensitive electronic equipment.  So the best strategy is to layer up whole house and point-of-use surge protectors for particularly sensitive electronic equipment such as computers, TVs, media centres, stereo systems, basically any device that uses a microprocessor.

Can I install a whole house surge protector myself?

Answer: This is generally not advised, as the process involves attaching the surge protector to the main electrical panel.  This requires careful assessment and wiring, which if done improperly, can mean electrocution or death.​

What does a whole house surge protector cost?

Answer: The price is dependent on various factors, but expect around $500 give or take a hundred or two for whole house surge protector installation and equipment by a licensed electrician.

How often should a whole house surge protector be replaced?

Answer:  Every two to three years is a good rule of thumb, but of course this is dependent on how many surges your home experiences, therefore extending or reducing the replacement schedule.

Do whole house surge protectors work against lightning?

Answer:  The best way to protect against lightning would be to unplug all your electronics, but seeing as this is not the most practical solution in the event of a lightning storm, the next best thing is to layer a whole house surge protection with point-of-use ones in the form of power strips or specialized outlets.

Do I really need a whole house surge protector for my computer (or other electronics)?

Answer:  This question is subjective because no one really NEEDS something that protects your electronics.  But the more sensible answer is yes, if you have delicate equipment in your home that would be more than just a hassle if it were damaged, then you should invest in a whole house surge protector (used in conjunction with the point-of-use protectors).
