"We had a great experience with Ryan Hamilton Electric when they came to work on our building and in our apartment. We had discovered that the knob and tube wiring that we thought had been removed from our apartment was still present, and so we hired Ryan to remove the old type of wiring and bring our unit up to code. Ryan and his assistant Tim went above and beyond when it came to doing the work. Ryan explained very clearly to us exactly what the issues were with the knob and tube wiring and showed us exactly what had to be done to fix the problem. We had no surprises. While we were hiring Ryan to remove the old wiring, we also asked him about doing some other electrical work in our apartment. Ryan was happy to add on these further improvements and charge us only for the materials since we were already paying for the labor. Ryan listened to our desire for improved lighting and better outlets, and he presented solutions that would work for us and our kids. He found the perfect lighting fixtures for all the bedrooms and the bathroom, and he offered to improve lighting when it seemed necessary. The project took a few days; Ryan made sure we had the temporary lighting we would need in the evenings after he had completed work for the day. Ryan and Tim also cleaned up beautifully each afternoon when they were done with their work. Ryan and Tim didn't just do exemplary work. They were also warm, friendly, and affable, and a delight to have working in our apartment. We will actually miss having them around, but we were so impressed and delighted by their work that we plan to hire them again soon to improve the lighting in the kitchen and to install new outlets in the bedrooms. R. A. Hamilton Electric has my highest recommendation. I am a very happy and satisfied homeowner."

FAQs for generator repair projects in Chelmsford, MA

There is often some confusion about the type of work these professionals do. They only work on electrical systems such as outlets, lighting fixtures and electrical panels – they aren’t appliance repairmen.

There are three types of electricians: Master, Journeyman and Apprentice. Electrical licensing varies quite a bit by state. Some have licenses for apprentices and some do not. Some have a master’s rank while others stop at journeyman. Despite the differences, they all require a minimum amount of experience and usually classroom time.

  • Apprentice electricians aren’t usually licensed and spend 4 years learning the trade. Throughout that time, they work on a wide range of projects to learn to become a Journeyman. They’ll do basic work like installing fixtures and replacing outlets all the way to assisting in wiring a home. Regardless of the type of project, they must always be supervised by a Journeyman or Master electrician.

  • Journeymen work without supervision. In a few states, this is the highest level available and they can do all levels of work from wiring a new home to installing a light. In some states, they need a separate electrical contractor license to run a business. In places with a master’s level, a journeyman can do all work besides design new electrical systems.

  • Master electricians usually manage a shop, design new electrical systems in new construction and oversee both Journeyman and Apprentices. They typically bid new projects. Though they focus on larger projects, it’s not unheard of for a homeowner to request a Master Electrician for a house call. If you do, expect to spend up to 25% more for the visit.

Generally, you don’t tip electricians, but that’s not to say they don’t appreciate it if you do. You can offer them something to drink or eat, like coffee and donuts. Most will appreciate it if you do.

The education and certifications required to become an electrician vary by state, though they generally follow this list:

  1. Apprentice

    • Does not always require a license depending on the state.

    • Learns on the job under Journeyman and Master Electricians.

    • Usually needs 4 years on-the-job training before they can test for a Journeyman license. Many states also require a technical degree to advance.

    • Always require supervision.

  2. Journeyman

    • Needs between 8,000 to 10,000 hours of on-the-job training and usually 500 to 1,000 hours of classroom experience.

    • Can usually supervise apprentices.

    • They can diagnose and repair electrical problems.

  3. Master

    • Achieved after an additional two years (4,000 hours) working as a Journeyman and taking the Master Electrician Exam.

    • Besides diagnosing and repairing electrical systems, they also design them. In most places they run shops and inspect Journeyman and Apprentice work.

    • Not a recognized rank in all states.

  4. Electrical Contractor License is an optional license in some states for a Master Electrician to run a business. Some states have this instead of the Master license.

Electricians make an average of $26 per hour but it ranges with experience and licensing. An apprentice may make about half that while a Master Electrician may hit closer to $40 per hour. This figure represents how much they make; not how much they bill. Their salary is only one component of their costs. They must also figure in overhead, taxes, equipment, insurance and several other expenses.

Leave electrical work to the professionals. Electrical systems are complex and potentially hazardous when not handled and installed correctly. If it were easy, it wouldn’t take 4 years to become a journeyman or 6 years for a master’s license. If you are determined to forge ahead yourself, understand home electrical safety before beginning any project.Even for simple common electrical projects, a licensed pro is best. Not only is it safer, but contractors guarantee and insure their work. Hire a professional to keep your home’s electrical systems functioning properly and safely.
