Types of Electricians

Electricians are specialized craftsman who install, replace, and maintain electrical equipment. Every type of licensed electrician requires training to take on various electrical jobs. Below you will find the four most common types of electricians.

 Residential Electricians

  • Residential electricians can install, replace, and repair electric systems in homes and apartment buildings (with single-phase electrical service). They also do electrical work outside of the surrounding areas. Their range of work can be a simple fix of an outlet or replacing lighting fixtures to rewiring a home or apartment building. Their expertise lies in these jobs, both large and small. Training combines classes, an apprenticeship which is usually four years under the supervision of extremely experienced electricians.

Commercial Electricians

  • Commercial electricians work on large commercial jobs and projects (with three-phase electrical service). They work in larger buildings with more complex and complicated projects. Not only do they install and maintain lighting and electrical services, they will also install workplace water heaters, commercial security systems, key entry facilities, fire alarms, and can even involve fixing heavy machinery. Before a commercial electrician is licensed, they must work under a master electrician for several years.

Journeyman Electricians

  • The majority of journeyman electricians work in construction, but they also work in other areas, such as large utility companies and manufacturing plants. They do not require as much supervision as residential and commercial electricians. They complete additional training courses and an exam. Once they have passed the exam, they don’t require extensive supervision. Journeyman electricians can work on both residential and commercial jobs. Typical work includes lighting system installation/repairs, security systems, and power supplies.

Master Electricians

  • Master electricians are highly skilled craftsman who have 7+ years of experience as an electrician. They generally work in a management or supervisory positions or own their own company. They also require additional ccourseworkand a master electrician exam. They are involved in overseeing their employees and projects to ensure they are done correctly. This could be the installation, repair, or maintenance portion of projects.

All electricians can do residential projects, but not commercial. Electricians typically start as residential electricians, then move into commercial because it’s more complicated. They may or may not become journeyman electricians and master electricians because this requires additional coursework, training and examinations.  Major benefits of moving up the electrician rank is higher pay and responsibility.

Electric Supply Center has all the materials every electrician needs for their jobs. With five locations across Massachusetts, feel free to stop by our counters or call today! If you have questions about which products each location carries, contact us.

Commercial Lighting Project in Boston

Reebok @ DryDock in Boston, MA – Part 1

When Reebok moved their headquarters to the DryDock area of Boston and needed their lighting project done ON TIME and WITHIN BUDGET, they turned to ESC. With an aggressive five-month timeline, ESC had to have impeccable project management and coordination with Reebok, the general contractor (Gilbane Building Company), electrical contractor, lighting designer (Lam Partners), and rep agents Boston Light Source and Apex Lighting Solutions and controls, supporting multiple manufacturers.

As you’d expect, a project of this nature comes with its challenges. The 220,000 square foot building is five floors, each floor having a different lighting schedule. ESC worked closely with Reebok and all involved to develop a strategy to meet the timeline and control systems requirements. This project only had a partial design when the five-month move-in timeline was requested. By working with the lighting manufacturer directly, ESC was able to ensure the lighting system had the backbone, capacity to fit out each floor and integrate with each subsystem even though the design wasn’t complete.

How was ESC able to accomplish this? Check out our post tomorrow and we’ll tell you!

Choosing a Carbon Monoxide/Smoke Detector for Your Home

no fire sign

Installing and maintaining a smoke and carbon monoxide detector is one of the best and least expensive ways that you can protect yourself and loved ones from danger. When you don’t correctly maintain your detector, you’re at risk for home fires and carbon monoxide poisoning, which can both be deadly. BRK offers a hardwired photoelectric/CO combination alarm for your home. As a new construction requirement for Massachusetts, this alarm comes with voice alerts.

Features of Smoke/CO Alarm

  • Photoelectric sensors are able to detect and identify various types of fire hazards in your home
  • Mounting bracket allows for easy installation and maintenance for alarm
  • Voice alarm allows up to 11 programmable locations
  • Varying and lower horn tones allows elderly with normal age related hearing loss to still hear the alarm
  • Alarm latch remembers which unit started the alarm
  • Low battery latch identifies which unit has a low battery

Regardless which type of alarm or brand you choose to protect your home, it’s important to remember to have one! It’s better to be over prepared with a dual-sensor alarm than not prepared at all. Learn more about the combo smoke and carbon monoxide alarm from BRK by contacting ESC at 781-272-7700.

Using Circuit Safety to Avoid Injuries

Whether you’re an electrician or contractor working on a commercial or residential property, electrical safety is important in any situation. One small mistake can be extremely harmful to not only yourself, but those around you as well. More and more, workers are being injured because they thought a circuit was turned off. Electricians and contractors should consider all circuits live until they are correctly tested.

To avoid electrical-related injuries, here are a few reminders of what to do before you touch a circuit:

  1. De-energize the circuit
  2. Lock out
  3. Tag out
  4. Test circuit
  5. Verify testing device

The steps below should be followed for every job to ensure you protect yourself and those around you:

  1. Before you begin the job, get information about the operations/construction of the electrical equipment you’ll be using.
  2. Ensure that everyone on your team is qualified to be working with electrical equipment and that any certifications are up to date.
  3. When you arrive at your job site, identify any and all energy sources that could be a potential hazard or danger.
  4. Make sure that you and your team are protecting yourself with the correct gear and equipment (googles, gloves, flame-resistant shirts, etc.).
  5. Follow the standard protection procedures (lockout/tagout).
  6. Verify that the electrical system has been de-energized by testing the circuit.
  7. Before and after you use your test equipment, be sure that it is actually working.

If you find that the job has become more dangerous than you initially anticipated, stop and review your plan. One of the most careless mistakes you can make is to assume that equipment is de-energized. Following the proper procedures can prevent injuries and death in some cases!

Finals Days of the ESC Murray Promotion

Circuit breakers are used to switch and protect your homes wiring from high temperatures, which are caused by excess current higher that the wire rating. Here are the different types of breakers:

  • Combo Arc Fault Circuit Interrupter (AFCI): Significantly reduces the risk of electrical fires by protecting against line-to-ground, line-to-neutral and series arcs, which are the three possible types of arc fault.
  • Branch-Feeder Arc Fault Circuit Interrupters (AFCI): Protects against line-to-ground and line-to-neutral arcs, which are considered high energy parallel arcing.
  • Ground Fault Circuit Interrupters (GFCI): Protects against severe electrical shock or electrocution caused by ground faults. These are installed to protect the kitchen, bathroom and laundry room of a home, which are the areas where electrical appliances may come into contact with water.

ESC has specials on Murray 1 Pole 20 & 15 Amp Breakers, 20 & 15 Amp Arc Fault Breakers and 120 & 115 DF Arc/GFI’s. Click here for more info on the ESC Murray promotion going on until Saturday, July 1st.
