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.

Most of us will not be leaders with the ability to speak and the bravery to act as Martin Luther King, Jr., but we can change the world for the better in small ways.  Even one bulb at a time…

The world of illumination is changing quickly and advancing into a new frontier with light sources that are more durable, more energy-efficient and better for the natural environment.  While we still have a choice, future lighting installations with LED (light emitting diode) lamps will provide the best light for your home or office space.

To make the best choice, there are a few lighting facts you should know.  All LEDs are not created equal, so read on to educate yourself and make a change to LED with confidence.

Learn what light sources are available and the limitations and benefits of each light source, so that you may choose the best one for each application.

•The right lighting will always help you look better, feel better and perform to the best of your ability.

•The right lighting will always be energy-efficient.

•The right lighting will always work well with the natural environment, making the most of sunlight streaming in during the day and delivering illumination in the most eco-friendly manner.

•The right lighting will last.  Choose good quality bulbs and light fixtures that are guaranteed to provide excellent illumination, equipped with fine finishes and components that are durable.

1.  KNOW YOUR BRIGHTNESS LEVELS IN LUMENS

New bulb cartons are required to prominently display the brightness level (measured in lumens (lm)).  In the past we have determined bulb brightness in terms of energy consumption in watts (W), but now we must learn to think in lumens (lm).  Here is a quick conversion chart to help get you started:

Lumens            Old Incandescent                                             LED

2600 lm————→150W——————————–→25-28 W

1600 lm———— →100W——————————–→16-20 W

1100 lm————→75W———————————-→9-13 W

800 lm————-→60W———————————-→8-12 W

450 lm————-→40W———————————-→6-9 W

2.  CHECK OUT COLOR QUALITY:   Correlated Color Temperature (CCT) and Color Rendering Index (CRI))

•CCT is measured in Kelvin’s (K) and is an important factor determining the quality of light for your specific application: Warm White or Soft White is about  2700-3500 Kelvin’s (K) and Bright White light is about 4000 K+

•CRI is measured on a scale of 0-100 and is an important measure of the degree to which your light source will show the true colors of all that is being illuminated.  Color rendering for decorative indoor lighting applications should be between 85-100.

3.  FACTOR IN DIMMING CAPABILITY

Most dimmers work by reducing the amount of electricity sent to the bulb.  But with LED the correlation between brightness and energy consumption is much different than with incandescent illumination.

Because of this difference, LEDs are not always compatible with traditional dimmer switches.  You either have to replace your switch with one that is compatible with LED or look for replacement LED bulbs that are compatible with standard incandescent dimmers.

4.  FIND SUITABLE BULB-TO-LIGHT FIXTURE MATCH-UPS

The reflector and fixture type will play a significant role in determining the light output from the light source (bulb).  Look at colored lenses and fitters, as well as shades and shielding to determine how they will help steer and direct your desired level of illumination.

When looking to replace an incandescent bulb with an LED bulb in a lighting fixture where the bulb will be totally enclosed, be sure to check that your LED is specifically made for an enclosed or recessed light fixture.  LED bulbs run cooler than others, but they do produce heat. To protect the quality of the LED chip and the performance of your LED light source, LED fixtures are specifically engineered to provide adequate heat-sinking.

5.  BEWARE OF THE LOWEST “BINNER” and COMPARE PRICE VS. QUALITY

“Binning” is the process by which LED chips are sorted.

Prior to being marketed in fixtures or light bulbs, LED chips are sorted into bins according to their light output (lumen output) and color temperature.  There are clear standards set to measure the lumen output of each LED chip.  LEDs chosen from bins with higher lumen output are of better quality.

Color temperature is determined by matching up each LED according to a chromatic line grid for a specific color temperature.   LEDs chosen from larger bins contain more color variation and are not as bright.

Due to the process of “binning,” LED chips vary in their quality—especially in relation to their lumen output and color, so it is important to purchase LED light bulbs and LED light fixtures from a reputable dealer.

September is National Preparedness Month—just in time for peak hurricane season in Maryland. Severe thunderstorms and floods are also common to the area and with winter approaching, it’s always a good idea to prepare for the possibility of heavy snowstorms. National Preparedness Month is a time to educate yourself on how you can prepare for sever weather so that if an emergency does occur, you aren’t left in the dark.

Every home and business should have a plan in the event of an emergency. Do you know what to do if cell phone towers stop working or the electricity goes out? While no one can prevent a weather emergency from happening, there are a number of things you can do to get prepared for any disaster. National Preparedness Month is a great time to:
