In the recent past, a mechanical contractor could install very inefficient appliances and equipment with no thought to energy costs. Energy rates were cheap; therefore, mechanical codes did not address energy usage. Mechanical code emphasis was on installation integrity, clearance to combustibles, and service space requirements. The installed equipment was very heavy and overbuilt. That all changed in the late 20th century due to several economic and environmental factors. These factors created a new buzzword: energy conservation.

Every electrician knows the basic standard of “the more experience you have, the more money you make.” To some extent, that’s an accurate statement. However, there are other, proven methods you can use to increase your value/pay, such as electrical continuing education and learning trade knowledge like NEC updates. Here are a few other basic methods to stand out to your employer.

According to the Bureau of Labor Statistics, the median wage for workers in the United States in the first quarter of 2019 was $905 per week ($22.62 per hour) which totals $47,060 per year. An electrician with just five years of experience can easily make much more than that by following these simple steps.

Derating conductors for the environment where they are installed is an important consideration for selecting the type and size of conductor for a particular installation. When installing a system on a rooftop, special consideration must be given to the ambient temperature inside the wire way or conduit that contain the conductors to prevent heating beyond the rating of the insulation of the conductors. Conductors installed in raceways on rooftops can be subject to higher temperatures than they would be just from the heating effect of solar energy absorbed by the wall of the raceway. This effect becomes more evident when the proximity is very close to the roof or the raceway is in contact with the roof surface.

Drinking water, wastewater, remediation, landfill, land application operations, and other operations are intertwined with little formal association with one another. There are occasions that these operations will meet to discuss issues, but mostly, if everyone does their job professionally, the all will continue without issue. Professionals in this industry are one another’s keeper in the effort to protect public health and the environment.

What if a refrigeration system could exist without a mechanical compressor, oil, or the typical blended refrigerant? A totally new design that required much less electricity to operate? Components of the system consist of an inert gas and large pressure vessels connected by pipes. This mechanism would be based on thermoacoustic principles that had very few moving parts. Considering the environmental issues faced today, wouldn’t it be an amazing achievement?

Transformers are used when power voltages need to be changed, or transformed, to other levels. Sometimes voltages need to be increased when sending power long distances. Other times, voltages need to be decreased for equipment that uses the power. Regardless of whether the voltages are being stepped up or stepped down, the same process of changing windings is used to transform voltages to different levels.
