To most people, circuit panels are the first place they go when power fails to a room.  The loud click heard when a space heater or hair dryer overloads a circuit usually calls for a quick trip to flip a circuit breaker back on.  Every building depends on the circuit panel for safety and electrical management for the home.  The electrical panel for your home, along with the attached circuit breaker, serves to delegate power throughout the home.  By splitting up power demands, it prevents overloads in separate rooms and isolates individual features and appliances.

You may be wondering why we need to split up circuits the way we do.  If all of our devices operate on 120 volts, why do we need separate circuits?  The answer has to do with the physical quirks of wiring.  You see, while everything operates off of the 120 volts delivered by your home’s wiring, the power demands are different for each device.  As power is applied to a circuit, current flows over the wiring and heats it up.  The higher your power demands, the more current is flowing through the wires.

The wires in your home can only handle a set amount of current (most circuits are 20-amp circuits) before they overheat and begin to ignite insulation around them.  If you placed every light, appliance, and TV in your home on the same electrical circuit, you’d reach this thermal limit almost immediately.  To prevent his, we install circuit breakers to help separate energy demands to specific rooms.  We also separate the energy load to create special appliance circuits.  This is why your HVAC unit is on a separate circuit from your kitchen and your laundry room.  Appliance circuits use thicker wires which are designed to handle higher electrical loads.  High current circuits are expensive, so homes are designed to use them sparingly.

This is also why you should only ever replace breakers and fuses with new units that have the same tolerance.  Circuit breakers are designed to be the weakest link in a system.  They must trip before anything on the circuit itself would fail.  This safety feature means that the breaker will trip before wiring overheats or appliances are damaged by high-current draw.  If you do need to replace a breaker, always match it with the same current-rating.

Power surges are another reason we separate circuits in a home.  Whenever a load is applied to the system (you turn on a hair dryer, electrical appliance, or even a lamp) inrush current is also applied.  Inrush-current is the initial surge of power that occurs when current is increased.  Extra power is applied across the system, which causes a risk of electrical damage when a high-power device is applied to a low-power circuits.  To mitigate this, high-load motors such as those in power tools, HVAC systems, and other appliances are plugged into special appliance circuits.  This is also why you should plug sensitive low-voltage electronics into surge protectors.

Sometimes electrical panels can wear out.  While the signs are clear when you know what to look for, without experience you have no way of knowing if it’s time to replace your panel.  Get an inspection for your electrical panel if:

If, however, you happen to notice one of two logos, Federal Pacific Electric (FPE) or Zinsco, you should call for a replacement immediately.  These older models of electrical panels are unsafe and should be replaced quickly.

While some might think of a garage as simply another room where you park your car and use as storage, it’s still part of your home and could be the cause of a higher energy bill. Helping make your garage more energy efficient will in turn lead to higher energy savings for your home.

Find out how to keep your garage energy efficient while saving money with our simple tips.

By insulating your garage and garage doors you can help keep the use of your HVAC down during the cold months. Garage doors tend to have several openings from which cold air can go through, causing the HVAC system to kick in more frequently than usual.

Turning down the temperature of your water heater to 120° F helps keep the water comfortably warm while reducing on unneeded energy waste. Lowering down the heat while on vacation also results in lower energy consumption.

Other tips for your water heater include purchasing a unit with a high Energy Factor (EF) rating that is more energy efficient, and routinely draining a bucket of water to help remove sediment that could cause issues.

Using warm or cold water instead of hot water to wash your clothes helps save energy up to $50 per year. Consider also investing in a front-loading washing machine, which use less water on average than traditional models.

When using the dryer, make sure to add a dry towel to help reduce the drying time. Keep yourself from running an additional cycle by not overloading your washer and dryer, which will cause your clothes to not be cleaned properly, and take significantly longer to dry. Cleaning the lint screen after every load helps keep the exhaust clean while reducing drying time and energy usage.

With the rise of energy efficient electric cars comes the need to keep a steady supply of fuel at home. Electric vehicle charging stations are a good choice, but oftentimes a faulty installation could lead to more serious problems down the line if installed incorrectly.

Having a professional and qualified electrician install EV chargers helps ensure that the correct voltage is being used and that the amperage will work best for your needs. They will also help you choose the correct model so that the installation location fits the length of the charging cable.

Garages are the perfect place for a handyman’s work station or home office and as a result, many might have power tools and various other electronics connected at all times.

As we mentioned in our energy guide for the living room, vampire appliances could result in wasted energy and time on standby mode. So if you’re using power tools or any other electronics, make sure to unplug them after use to help keep the costs down.

Light bulbs usually consume more electricity than an LED so replacing them is a wise choice. LEDs not only help reduce your carbon footprint, but they also need to be replaced less frequently and consume less energy making them a perfect energy efficient option.

Often times, the lights will be left on as you forget and move to other rooms in your home so consider investing in a light timer which can automatically turn the light off after a set amount of time.

While having a spare refrigerator or freezer in your garage might be a good idea for keeping spare food safe, it’s often wiser to get rid of it or replace it with a more energy efficient model.

If you’re not ready to get rid of the appliance, at least unplug it to help keep unneeded energy from being wasted.

How many times have you observed your neighbor using a weed-whacker that is connected to a series of four or five extension cords in order to reach the far corner of the yard? Probably plenty of times. When using a series of cords, be sure they are all the same rating, and check with the manufacturer or your local licensed electrical contractor to see if it is safe.

Extension cords are rated by the thickness of the wires inside using a standard known as AWG (American Wire Gauge).

Using air ducts in order to distribute both heated and cooled air throughout a building is one of the most common ways in which homeowners choose to keep their homes comfortable all year long. Doing so, of course, means that your air ducts are in play throughout the entire year. Are you certain that yours are in the condition necessary to perform their job precisely as intended? If not, give FB Electrical Services a call today. We are more than happy to thoroughly test your air ducts so that you know what kind of shape they are in. Once we have completed your duct testing in Somerville, we can go about resolving any problems that we may find with your air ducts. That way, you can heat and cool your home at peak performance and efficiency levels.

When you stop and think about it, you have likely seen very little of your air duct system. For the most part, your ductwork is hidden from view. The last thing that you want to do, though, in terms of your ductwork, is to develop an “out of sight, out of mind” attitude in regards to their condition. Leaky ductwork is one of the main sources of energy loss and low efficiency in many homes, and it is also one that professional duct testing can help to pinpoint the source of. When we test your air ducts, we can determine with certainty if it is compromised, and we’ll have the information we need in order to right whatever wrongs we may find.

As a facility manager or building owner, it is nearly impossible to know everything about everything in your building. But it is vital to know something about everything, and that goes for your facilities lighting system too. Whether you manage a warehouse, factory, or other industrial sized building or space, the lighting is a huge factor of many things including safety, productivity, and consistency in the work in your facility.

So while you don’t need to know every facility managers and building owners should know about there lighting system and how lighting can make all the difference in various amounts of ways.

1. Not all lights are created equal. This is an obvious one, not all lighting technologies are created the same and all output at different levels. Firstly you have lighting technologies that are less efficient than others. Such as metal halide and HPS which are 2-3 times less efficient than LED technology is. Then you also have efficiency based on a “product to product” basis. For example; while LED is the clear winner in efficiency over metal halide (and really any other lighting technology), one LED product from one company isn’t going to be the same as the next company’s LED product. This is where you really need to dig deep and find the company that offers the most efficient lighting products over all other companies.

Key takeaway? First, understand that LED is the most efficient in a general sense, but also understand that each company and product varies on its own personal efficiency and you should always do your homework before going with one LED product over another!

2. New lighting system upgrade costs can be reduced with rebates. This is only a true statement when you are buying commercially qualified lighting products that are DesignLights Consortium qualified. return on investment overtime by decreased energy costs associated with running your lights. Obviously this ROI period will vary depending on how long you run your lights per day on average, but especially in big facilities they almost always are used often and thus, provide a good and even quick payback period.

4. Create safer environments with a proper lighting system. With low quality light output, you create an unsafe environment that can cause various issues. Lighting fixtures that aren’t outputting the proper amount of light after a few years into there life is all caused reasoning to retrofit over fully replace.
