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.

Modern living is highly dependent on electricity and we use energy to cool our homes in the summer and heat our homes in winter. Either way, we end up using a significant amount of money of utility bills right through the year.

When the temperatures dip it is but normal for us to turn up the air conditioning by a few degrees when we are at home. We may also use space heaters in certain areas of our homes and end up using more hot water as well. This makes it almost impossible to keep a handle on our utility bills during the winter months.

So, is there nothing we can do to make sure that we are able to cut costs in some way or the other? Well, there sure are a number of ways in which you can increase the energy-efficiency of your home; here are some tips that will help you stay warm in your home, and use the appliances you need, without breaking the bank:

This is one of the simplest things you can do to reduce your electricity bills in the winter. You should make use of natural light and keep the blinds open for a large part of the day. This will bring in more warmth into your home and you will find that you don’t have to run the HVAC system at higher temperatures, at least during the daytime.

When it comes to crime, it’s evident that there’s an appeal to darkness. Less visibility means less chance of getting caught. The 2014 National Incident-Based Reporting System (NIBRS)—an annual Uniform Crime Reporting (UCR) Program publication that’s released by the FBI—includes detailed crime data, such as time of day and type of offense. More than 18,000 law enforcement agencies participate in the UCR Program and provide data voluntarily. NIBRS’ Crimes Against Persons data shows that of the 1,093,466 incidents reported in 2014, 562,104 (51.4 percent) were between the hours of 6 p.m. and 6 a.m. Crimes Against Property data shows a lower—yet significant—39.4 percent of 3,493,904 reported incidents taking place between those same hours.

In an attempt to lessen crime and increase energy savings, many cities and businesses have started replacing traditional high-intensity discharge (HID) lights with LED bulbs, light engines, and fixtures. These actions have paid off. In 2008, Los Angeles began a project to retrofit 215,000 lights with LED lights. Since implementation of the project, color-rendering indexes (CRI) than HID fixtures. CRI refers to how accurately a light source reveals the true colors of objects, people, and surroundings. The CRI of an HID bulb can range from zero (high-pressure sodium) to about 65 (metal-halide). LED fixtures are capable of having CRIs of 75 and higher. Lights with a CRI of 80 or higher are considered to show colors most accurately and increase visibility, which is especially important for security purposes and parking lot surveillance.
