Kauai’s electrical grid surges affect the life span of our computers, appliances, and other electronic equipment. Power surges can also completely roast the internal electronic parts during a storm or utility fault.

A whole house surge protector installed by a licensed electrician will greatly decrease the risk of power surge destruction.

Guarding against surges requires a two-pronged approach: a whole-house suppressor to tame the big, dangerous power spikes and an individual circuit (or “plug-in”) surge suppressor for vulnerable appliances and electronic devices. Both types essentially act like pressure-relief valves. Normally they just sit there, allowing electric current to flow through them. But with higher-than-normal voltage, the devices instantly divert excess voltage to the ground wire. (The best ones react in less than a nanosecond.) As soon as voltage levels return to normal, the flow of electricity is restored, unless the surge was big enough to melt the fuse built into some units.

Typically, whole-house suppressors are hard-wired to the service panel, a process that takes a licensed electrician about two hours. Whole-house systems should be rated to stop a 40,000-amp surge, at minimum. Features to look for include thermal fuses, and lights or alarms that indicate when a device has taken a hit. Protection for an average house with 200-amp service will run about $500 — including a couple of hours of an electrician’s labor. Separate but smaller whole-house units are recommended for the phone and cable lines. These protect fax and answering machines, televisions, and modems.

By themselves, whole-house suppressors can’t stop surges completely; up to 15 percent of excess voltage may leak by. That’s where “plug-in” surge protectors come in. These buffers between individual appliances and wall outlets come in a bewildering array of options and prices. They range from $70 units not much bigger than a computer mouse to $350 units the size of a pizza box that guard all the components in a home theater. But most plug-in models fall into three basic categories: the familiar multi-outlet power strip; the multitasking surge station that can handle phone and cable jacks as well as power cords; and the UPS (uninterruptible power supply), which completely cleanses electric power of random fluctuations and provides a short-term battery backup in case the power dips or goes out entirely. Expect to pay between $20 and $70 for a quality power strip or surge station, and from $100 to $250 for a UPS.

Now that spring is well on its way, many enterprising homeowners are looking forward to home improvement projects and renovations to their homes. What they likely are not looking forward to, or may not even realize that they have to consider, though, is scheduling inspections and pulling permits. Not every job is going to require a permit or an electrical inspection, but many do, and they are not always the jobs that you’d expect. Language in permitting regulations may necessitate that you pull a permit for replacing a window, for instance, as this is an egress. The best way to ensure that you are doing everything by the books is to hire a skilled professional to do the job.

When it comes to an electrical inspection, it is all about your safety. Once your contractor has finished his or her work, or even just the rough work phase of the job, having an electrical inspection is most likely going to be necessary. This guarantees not only that any existing electrical systems and components in the area are in great working order, but also that nothing was compromised during the home renovation process. You need everything in your home to be up to code, and it is in your best interest to ensure that this is the case prior to the completion of the entire project.

There are a lot of questions surrounding this particular practice, and nobody wants to go through the process of pulling permits prior to getting a project underway, only to find that the permit was not necessary. That being said, allowing a contractor to work on your property without the necessary permits can have some pretty serious consequences. If a complaint is filed, and an investigation opened, the work will have to stop. Any improvements made may actually need to be removed, and you may face considerable fines. There will likely be a lot of red tape that will seriously delay your project, as well. Contact the appropriate governing bodies in your area to know for certain if a permit is needed.
