During the summer, your attic fan vents heat out of your home’s upper region. Obviously, during the winter, you don’t really want to be losing heat. What you may want to be losing, though, is excess moisture and humidity in your attic. You see, heated air moving through a home can pick up moisture on its travels. While winter air is dry, acts such as bathing, doing the dishes, and more, all in a home tightly sealed against the winter elements outdoors, can lead to the introduction of quite a bit of water vapor into the air. Warm air tends to rise, of course, so that warm air, and the moisture that it contains, can make its way up into your attic. Once its up there, the moisture in that air can lead to problems with damaged insulation due to condensation, and even long term issues with wood rot.

Additionally, the heat that rises into the top level of your home can also melt snow that has accumulated on your roof. Once it has melted, that snow melt can freeze in your gutters, causing ice dams. This can pull the gutters away from the house, due to the weight, causing external damage. By exchanging hot, moist air from inside the attic with cooler, drier air from outside, you can avoid such problems via the use of an attic fan. Call for more details.

So, you want to become an electrical contractor/engineer? Selecting electrical work as a profession brings several rewarding growth opportunities. After all, the need for electricity is on the rise in today’s society. But before you reach a decision, it’s not only important for you to know the numerous duties of an electrical contractor/engineer, but also the requirements for becoming a certified electrician.

Luckily, in this article, you will learn everything about becoming a certified electrical contractor in a step-by-step process. It doesn’t matter if you are looking to start a career in electrical contracting, or are still only considering it, the information provided below will prove useful. Here’s what you need to know:

An electrical contractor or engineer designs, develops, tests and installs electrical hardware, systems and equipment. They work in a variety of settings, including commercial and residential structures. To become an electrical contractor, you have to receive extensive training and obtain a license according to the local regulatory guidelines and standards which apply to your country.

Steps to Become a Certified Electrical Contractor

Several schools and colleges offer instructional programs for prospective electrical contractors. Moreover, a bachelor’s degree in electrical engineering offers comprehensive training in electrical design and systems. Academic programs generally include hands-on coursework and internships to help you gain practical experience.

Novice electricians can also gain supervised training under an experienced master electrician through apprenticeships. National organizations, state agencies and unions can introduce you to contractors and companies offering apprenticeship programs. These typically require a high school diploma. If you qualify, you will be offered paid positions that will last at least five years.

As mentioned earlier, electrical contractors perform a range of services for commercial and residential properties. In addition to installing and maintaining electrical systems, hardware and equipment, electrical contractors also train and hire new electricians, do administrative work, as well as plan and schedule projects with clients. They can be an integral part of the team involved in the building process, ensuring the electrical systems are up and running before the final work is completed.

Therefore, mentored training and experience in various electrical positions will provide you the industry-related and foundational knowledge and skills required to become an electrical contractor. Additionally, working under a master electrician can give you the experience and skills required for a journeyman or novice electrician to obtain a license, get certified, and perform independent work.

Some countries require electrical contractors to acquire an electrical contractor or master electrician license, while others don’t. If it’s mandatory in your state or country, you can obtain your license from the relevant state boards. However, keep in mind the requirements to get licensed will vary from state to state.

But generally, the requirements include meeting the experience requirements by working under an experienced master electrician, paying a certain amount as fee, as well as passing a written examination. Also, your license has to be renewed every few years, where you will have to pay the fee as well. You should contact the licensing agency in your state for a clearer picture about the requirements.

Once you have acquired your license, you are a certified electrical contractor and start working independently, or by joining a contracting company. But you should also understand that being an electrical contractor requires ongoing education to stay up to date with the technical advancements in the electrical domain, as well as any changes to the standard electrical code.

Electrical contractors with enough experience under their belt can also consider starting an electrical contracting business of their own. By starting your own business, you can increase your earnings from your work. Not to mention, you will have increased scheduling flexibility, which means you can employ other electricians to work under you and dispatch them to work on projects offered by clients.

And with that, we come to the end! As you can see, this article covers all you need to know to become a certified electrical contractor. Hopefully, now, you will have a better understanding about the requirements and duties the job entails.

A lot of time we are asked what is the equivalent LED product to convert from Metal Halide, High Pressure Sodium or Mercury Vapor. And a lot of time, we have a product in mind that works based on past experience. But how did we come up with that product, and how did we make the original decision on what was the proper replacement?

There’s a lot of science that goes into light, color, quality, and each light had it’s own characteristics. For example, it takes less LED to replace High Pressure Sodium than it takes to replace Metal Halide. And we are talking a lot more than just lumens. We are talking about color temperature, quality of light and something called photopic / scotopic lumens.

In the world of lighting, we measure foot candles with a light meter, this is called a photopic measurement. The light meter picks up everything, including spectrum’s that are invisible to us. Now, we humans see things to, and this is called scotopic lumens. Our rods and cones read and interpret light. And it does so differently than what a light meter does. So it is not uncommon when we demo a LED Light against a HPS light or Metal Halide, we first ask “Which is brighter” before we show the light meter reading. It leaves a few people scratching their heads. Well, that’s the science of of it all, and fortunately there is some handy tables called SP ratios that allow us to take the lumens of a particular light (photopic lumens) and multiply it by the S/P ratio to get the scotopic lumens equivalent.

For example, the S/P ratio for High Pressure Sodium is 0.40. The S/P ratio for LED at 5000K is 1.8. So if you take 40,000 lumens of HPS and multiply it 0.4, the effective scotopic lumens is 16,000. To get the same amount of lumens from LED, take the 16,000 and divide it by the S/P ratio and you get 8888 lumens. So the 8888 lumens of LED is the photopic measurement, the 16,000 LED lumens is the scotopic lumens measurement. So in an nutshell, you need 8,888 lumens of LED to replace 40,000 lumens of HPS from a scotopic point of view.

Here is a handy chart of common lights and ratios for you to use.
