NEMA or the National Electrical Manufacturers Association has developed rating standards for electrical enclosures to ensure safety, compatibility and proper function of electrical products. These ratings provide the standards that help in defining the types of environments in which various electrical enclosures can be used. NEMA ratings frequently indicate a fixed enclosure’s ability to withstand certain environmental conditions.

NEMA ratings are mainly applied to fixed enclosures and are rarely applied to mobile devices. They have extremely stringent testing requirements to verify if the enclosures can be protected from external ice, oil immersion, corrosive materials, dust, water, etc. Each NEMA rating has different specifications; however, all of them are designed to protect electrical components, personnel and property from damage.

Importance of NEMA ratings

If you use any kind of electrical enclosure, it is important that you check its NEMA rating before installing it. There are a number of reasons why it is important to do so. Let us look at three reasons why NEMA ratings are important.

A good number of the calls I get during an average day at work fall into two categories;   customers who call to have something installed in their electrical system, and customers who tried to install it themselves and are calling me to come and fix the mistakes they made.  There’s certainly nothing wrong with trying to perform basic electrical work yourself if you have a good grasp on proper electrical safety techniques and what you’re doing.  On the other hand, there’s nothing wrong with calling a top Dallas electrician to do the work for you either.  The best way to ensure the job is done right every time is to hire an honest, hardworking professional electrician who’ll stand behind his work.

Even tasks that can seem quite simple can be treacherous if you’re not sure what you’re doing.  This comes into play a lot when a homeowner is trying to perform a three-way switch installation.  It seems a lot easier to install than it really is; I generally recommend homeowners not attempt to install three-way switches without at least a electrician on the phone to walk you through the process.  Keep the following in mind:

There are tasks well suited for the do-it-yourself minded homeowner, though.  The easiest is wall outlet replacement, which is usually a very simple, straightforward procedure.   That doesn’t mean the haystack isn’t free of the odd needle that you can hurt yourself on, though.  Here are some of the more common problems I run into, along with some typical solutions or hints to keep them from happening to you: 

As we venture further into the era of climate change, humans are constantly searching for ways to decrease energy consumption and increase efficiency. Unfortunately, there's no silver bullet. Truly reducing our impact on the global climate requires a combination of an increase in renewable power generation, behavioral changes to decrease consumption and increasing the efficiency of our homes and appliances. Even as we strive for improvement, sometimes we fall short. According to a new study from the University of California, Berkeley, for example, a federal Weatherization Assistance Program is not bringing in the expected efficiency benefits.

Looking for the Win-Win

Investments in home efficiency are usually considered win-win scenarios. Reductions in energy consumption lessen the impact on the environment and reduce energy bills at the same time. Many upgrades, like replacing an outdated refrigerator with a new Energy Star-certified model, will eventually pay for themselves in energy savings.

However, not every savings promise comes through. The Berkeley study looked at 30,000 households in Michigan that upgraded their home systems with new insulation, weather stripping, HVAC equipment and more. The federal government paid up to $5,000 per house for the improvements, but the average household only realized $2,400 in savings during the lifespan of their new efficiency features. That's not a great return on investment.

Ancillary Benefits

The households saved 10 to 20 percent on their energy costs, on average, which is only about 40 percent of what they were projected to save. The results are discouraging for consumers who are striving to implement any cost-saving measures they can find. Electricians and home service technicians can help you upgrade your home systems, but the changes will only go so far.

There were other benefits to the weatherization program outside the raw financial data, of course. The investments were aimed at low income households, so the money saved helped reduce poverty in the area. Plus, the reduction of carbon in the atmosphere from the program has additional economic benefits. Nevertheless, the disappointing result could be a blow to the willingness of the government to make similar investments in the future.

Let the Buyer Beware

The big lesson for the consumer? Don't believe just any claim about energy efficiency, and do your due diligence before investing in a big-ticket upgrade. You can and should make efforts to reduce your energy consumption, but be careful not to blow your investment dollars on items that don't give you a good return.

"This underscores the value of field-testing," paper author Michael Greenstone said to Vox. "Particularly in a world where economy-wide carbon pricing does not look feasible, we should be redoubling our efforts to find those CO2 reduction measures that have the biggest bang for the buck."

If you need advice on how to get the best return when it comes to energy efficiency, find an experienced electrician who can help you invest your dollars wisely and steer you away from less effective purchases.

Energy Efficient Lighting Solutions for Aging Eyes

As people get older there is more time to really enjoy the homes they have built for themselves. The kids have grown and moved away, and being physically comfortable has, perhaps, become more important than it once was.  Knowing that aging eyes need a better kind of light and more of it to be comfortable, remodeling the lighting in your home improves comfort threefold.

“Baby boomers are finding that they need three to four times as much light and that glare is hard on the eyes,” says Norm Brown, CLC, of Norburn Lighting & Bath Centre in Burnaby, B.C., and a consultant for the American Lighting Association (ALA). “Fluorescent light bulbs are easier to see by than regular light bulbs. LED lights are being used more for their reduced glare, as well as Halogen, for their white light quality. You can choose energy-efficient bulbs in many styles for redecorating your whole house.”

Capitol Lighting offers ceiling, wall-mounted and portable fixtures, and recessed and track lighting in energy efficient compact fluorescent bulbs as well as light-emitting diode (LED) lights to help aging eyes.
