The home electrical system consists of various components that enable the safe delivery of energy to different sections and appliances in the household. Even though the system may appear complex, it is important for the homeowner to understand a few basics.

This would help you when things do not work or there is an emergency that requires turning off circuits or the entire installation. In addition, an understanding of the home electrical system will help the owner respond to questions from prospective buyers.

All the electrical circuits in the house originate from the main breaker panel. The panel is usually inside the house and near to the power entry point. However, the panel can also be far, and especially when in a multi-family structure.

The rating of the panel determines the number of circuits and power that the home electrical system can support. Some older homes have been using the 100 Amp service, smaller installations use a 60 Amp service while newer and larger houses are built with 200 amps to accommodate the increased number of electrical and electronic equipment commonly used in a modern household.

Different loads require the correct size of cables and breakers that can handle the current without heating up. For example, an air conditioner requires a 30 amp circuit while a kitchen may use two 20 amp circuits.

If there is a fault, such as a short circuit or overload, the breaker trips and cuts off the power to the affected circuit, hence preventing further damage that could lead to fire. Before resetting the breaker, you should first ask an electrician to check and rectify the problem.

A home electrical system consists of different individual circuits originating from the main breaker panel. The wires from the panel run to the rooms to supply the outlets, lights, and hand wired appliances. In most cases, several rooms may share the same circuits such that all the lights in the house are on one breaker, outlets on another breaker, etc.

Some dedicated circuits from the main breaker may go directly to the hard-wired appliances and nowhere else. Equipment such as the electric water heaters, furnaces, and air conditioners are usually installed on their own. Other hard-wired devices include the smoke alarms, which may also have battery backups so they will work even when there is a power outage or a fire interrupts the home electrical system.

Grounding is an essential protective feature that must be installed in all home electrical systems. It provides a path for the electrical current arising from faults that make the exposed metallic parts to become live and dangerous.

The ground connects all the exposed metallic parts to the earth mass through a third wire in the power cord to the equipment. This provides a low electrical resistance path for the current, hence, making the parts safe to the touch even in the event of a malfunction.

Giant windows are great if possible. That’s a big IF, though. Sometimes, natural light isn’t an option, either because the laundry room is subterranean or otherwise windowless. Obviously, in the image below, natural light is not an option. Yet, the color temperature of the ceiling light is neutral enough to make this laundry room bearable while another, poorer lighting choice could have made this tiny laundry room annoying to visit and kind of scary.

You didn’t think I was going to avoid talking about lighting solutions just because natural light is such a great option for laundry rooms, did you? So, how should you light your laundry room? For any type of laundry room, there are some fundamental guidelines.

I’ve already suggested that you ALWAYS USE NATURAL LIGHT, when and if possible. And for your other light sources? Consider choosing lights with a Color Rendering Index (CRI) of as close to 100 as possible. A light source’s CRI is, in effect, a metric by which to compare the ability of artificial light to render color as well as the sun. 100 is the maximum CRI. Some lamps, like low-pressure sodium lamps, can actually have really low CRIs, while there are now some LED lights with CRIs of 95 – 98. If the sun isn’t shining in your laundry room, there are plenty of excellent options that closely match natural light’s ability to render color and help you keep your clothes clean and fresh as can be.

Layer your lighting.

OK, so this is the main theme in pretty much all lighting design guides. Layering your light pretty much means that you should think about general light, accent lighting, and task lighting. In the main section of a house, this might look like mini recessed ceiling lights with square bronze trim, elegant track lighting to spotlight a painting or picture, and a reading light by the chair or some under cabinet lights illuminating the bar counter. In a laundry room it might look like the image below.

Sometimes, in larger laundry rooms, you can have all three kinds of light. But, generally speaking, laundry areas are on the smaller side and are too focused on pragmatism for decorations that would benefit from accent lighting. Keep in mind that this is a generalization with exceptions galore, but, generally, the two kinds of lighting you’ll find in laundry areas are ambient overhead lighting and task lighting, and this scheme usually takes the form of a ceiling light or two and under cabinet lighting.

Creative Options.

It’s 2013, and if you’re still spending a ton on your energy bill, you should know that it doesn’t have to be that way. Right now, about 20% of the energy we consume goes to lighting. But, with a few energy-efficient changes, we can see that number (and the numbers on our monthly bills) dwindle. This post is the first in a series on how to make the lighting in your home or business more energy-efficient. 

Everyone’s got to eat, and for many of us, the kitchen is the very heart of the home. The kitchen also requires excellent lighting for cooking and cleaning up. So, I figure it will be a good place to start an energy-efficient lighting makeover.

Every commercial space, whether it’s a hotel, restaurant, office, department store, small shop, school, or hospital, can benefit from switching to LED lighting. LEDs are energy-efficient alternatives to halogen, and Universal LED Bulb Finder to search by bulb type, or browse our site to see hundreds of lighting options.

There are many LED recessed lighting options for existing can lights, eyeball lights, or other recessed commercial applications. Traditionally, recessed fixtures contain either a PAR halogen bulb or a BR incandescent bulb. These bulbs are available in several different sizes, and each type has its own set of features. BR bulbs typically have wide flood beam patterns and allow for more of a gradual fade of light. LED replacement PAR and BR bulbs have those same features but with increased energy efficiency and longer life spans. Complete LED fixture replacements, such as downlights, are also an option.

When it comes to commercial lighting, one of the most popular fixtures is the fluorescent panel light with T8 tubes. These panels offer little in the way of quality lighting. Hot spots are visible even through their textured lenses, and the light that they emit has a yellow-green hue. CRI), which is the key to showing the true colors of objects and surroundings. They emit crisp, clear illumination with no visible hotspots, and you won’t have to worry about replacing them for a very long time.

It’s no secret that a well-lit sign will stand out more than one that is poorly lit. LED sign modules are available in many different intensities and colors to illuminate signs, light boxes, marquees, and channel letters. Because LED bulbs can last up to 25 times longer than incandescent or halogen alternatives or approximately five times longer than fluorescent tube lights, the need for replacements is few and far between.

Now that winter is around the corner and the temperature is already dropping, the heating bills will start to increase. Here are a few ways you can keep down your expenses this season.

Using electrical space heaters will also help you control the heating expenses. Electrical space heaters are a cheap way to heat only the rooms that you are using. They will be more efficient then turning up the thermostat for the whole house, but don’t leave them running all day. Just make sure that you keep your heaters away from curtains and furniture, and keep any children or pets from burning themselves.
