A power surge is an increase in voltage flowing through your electrical units that rise above the standard voltage levels (120 Volts). These surges can be caused by lightning, high-powered electrical devices (elevators, air conditioners, refrigerators, etc), faulty wiring or even problems with your utility company’s equipment. Inevitably, these are all occurrences that we cannot prevent ourselves, so how can you protect your home and equipment from these damaging power surges?

Surge Protector

A simple solution is plugging in your electronics into a surge protector. A surge protector is a device used to protect your electronics from damaging power surges. However, many people use this tool for a much more obvious function, to plug in multiple components into one outlet, not knowing its protective capabilities. You most likely use at least one surge protector in your home already. But how does it work? How do you know that you are providing the top quality protection for your important devices?

How it Works

As you know, your surge protector pulls electrical currents from one outlet and passes them through all the electrical devices plugged into the surge protector. This aside, the more important feature of this device is its metal oxide varistor (MOV) component, which diverts extra voltage and preventing it from damaging your electronics. This MOV acts in different ways depending on the voltage flow to provide your devices consistent access to adequate levels of power. If the MOV indicates high levels of voltage, it will reduce the resistance and if the voltages are low it will create a higher resistance. However, it is important to be aware that these MOV’s can also burn out. By investing in a power surge with an indicator light you will always be able to determine whether or not it’s functioning appropriately.

A microwave is basically standard in any home these days, along with refrigerators, washing machines, etc. But do you know very much about your microwave? Furthermore, is it important that you know anything about your microwave? You might be surprised by our answer!

At Kolb Electric, our experts make a point to stay up to date with any and all information regarding modern electrical practice, the workings of appliances and how they impact your home. Why do we tell you this? So you know we know our stuff when we say wattage is the single most important factor in choosing a microwave! Well, that and a popcorn button.

Avoiding the potential (and boy, is there potential) for a massive science lesson, wattage boils down to a unit of measurement for a unit of power. In how your average person understands it, wattage is how much power an appliance utilizes to operate.

Microwave wattage generally spans between six and twelve hundred (600-1200) watts. You can see the wattage of your microwave on either the original package, or on the bottom of the unit. It will either have a number and say watts beside it, or it will simply have a number and a “w”, which means watts.

Understanding the wattage of your microwave tells you a few things. In a practical sense, it tells you how strong the microwave is. This is why “cook times may vary”. It also tells you what your microwave needs to operate smoothly. Many microwaves require a dedicated circuit to operate smoothly. We’ll go further in depth on this in a moment.

But, why have varied microwave wattage?

Well, there are a few good reasons. Many homes and older building simply can’t handle the supply need of higher wattage appliances, thus lower wattage options are available. Additionally, larger or more powerful microwaves are (naturally) more expensive. So, there’s a practical reason, and a cost-based reason.

What was that about a dedicated circuit?

Many homeowners feel that just any old outlet will do for their microwave. Most of the time, they learn they’re wrong the hard way. Microwaves require a dedicated circuit because it’s code and legally required, and  because not having a dedicated circuit can lead to breaker flips, power surges and permanent appliance damage.

Microwaves are high-power items, and use some of the highest wattages in your home. Furthermore, they use energy in a very intense way, which means a microwave can stress your circuits like no other.

We hope you learned something useful (or at least a little interesting)! Do you know if your microwave is on its own, dedicated circuit? If not, contact a Kolb professional today!
