Purchasing a new home can be both an exciting and stressful experience. While you may like what you see on the outside, we all know that there can be problems hidden behind the walls. When it comes to electrical, not only can improper work cost you lots of money, but it can also be dangerous. If you are browsing for a new home, make sure you are cautious of possible issues that can arise.

As we have written about in the past, the main service panel is a critical part of the home electrical system. This is what controls the electricity in the entire home. Over the years these panels can become old and worn. Sometimes additions may have been made to the panel, but not done correctly. When looking at a service panel it is important to look for any loose or wires and connections into the panel. The wires should be tight to avoid electrical outages and flickering. Loose wires can also cause sparking and lead to fires. An expert electrician can also identify the amount of wires going into each circuit breaker and the organization, which can help with safety and efficiency.

One concern many people have is what kind of wiring is behind the walls. Many of us have heard of aluminum wiring and that we should avoid it. The problem with aluminum wire is that the wires can become loose more easily and also heat up, becoming more prone to electrical fires. Old knob-and-tube wiring can also become weak, break easily, and cannot function at today’s standards. It is a good idea to have an expert electrician inspect the wires in your prospective home to make sure they are safe or whether they need to be upgraded.

Outlets in the home should also be easily tested. Check to make sure that none of the electrical outlets look burnt, dirty, or are loose. Outlet testers can be test to make sure that they are properly grounded and being fed electricity properly. It may appear that the outlets function properly and can continue to do so without being properly grounded. But in the event of a power surge, especially in a major appliance, the electricity will not escape through the grounded wire and can cause electrocution.

These are just some of the potential electrical problems that a home can have. In order to protect yourself and your investment, have a home inspector visit the home. If you have just purchased a home, have an electrician inspect it for any possible issues and for a more thorough analysis.

The list of rules to be followed when installing new electrical systems into a building are related to the specific rules of the state, as well as certain minimum requirements laid down by Federal law. So in some senses the United States does not have a unified Electrical Building Code, because often there are variations between different states.

It was to address exactly this issue that the National Fire Protection Association, a panel of nineteen different bodies, began publishing the National Electrical Code (NEC) in 1897, and now every three years, in order to arrive at a single source of rules that should govern electrical installations. The current version was published in August 2010 and runs to over 1000 pages.

Whilst the NEC is not law as such, in practice it has been adopted by most states as their set of rules for electrical installations and wiring in buildings (with a few changes here and their depending on the state you are in), and so is now in practice the Electrical Building Code for the United States.

This is the book that all Journeyman Electricians will consume when undertaking their training, as it is pretty much the standard version across the country.

Though there are some differences between the states, and you can see the individual requirements for your state here: State Regulations

Some of the key NEC rules that need to be followed when installing a new electrical system into a building are:

If you are planning on installing electrical wiring then you should refer to the NEC and your local Electrical Building Code for specifics and to the link above for any state specific requirements that you need to know.

The chandelier used to mark your arrival. Clad in crystal, it met you in the foyer of a well-appointed home, then dazzled you from a power position over the dining room table.

Rarely did you find a chandelier in a starter home. To see them illuminating any room other than one used for entry or dining, more unusual still.

My, how times have changed!

Today chandeliers rate as a brilliant idea just about anywhere — from modest homes to magnificent mansions, contemporary digs to traditional houses. They dangle decorously in almost every room of the house.

Credit our bigger-is-better building boom. Taller ceilings and increased volume in today’s homes means chandeliers are less likely to crowd a room.

“Nine-and-10-foot ceilings almost demand something hanging to fill the space,” says Joe Rey-Barreau, educational consultant for the American Lighting Association (ALA) and assistant professor of interior design at the University of Kentucky. The ALA is a non-profit organization of leading manufacturers, retail lighting showrooms and sales representatives in the U.S. and Canada dedicated to expanding public knowledge about lighting.

Colorful chandeliers create drama in the kitchen. Mini ones provide elegance to powder rooms. Even walk-in closets go upscale when lit with a small chandelier.

“Beyond laundry rooms and garages, any room is an open target for hanging a chandelier,” adds Rey-Barreau. “More commonly, kitchens and bathrooms have become the popular locations for chandeliers.”

Chandeliers add twinkle to a boudier. “People are treating their bedroom suites as more luxurious personal spaces with elaborate bathroom areas, so it is not unreasonable to consider chandeliers there, either,” says Dan Blitzer, Director of Education for the ALA..
