MTI’s Electricity program has been developed to provide students with the essential theory and hands-on practical experience on residential and commercial wiring techniques and applications, as well as, industrial controls.   Electrical is a licensed trade that requires not only highly technical knowledge and skills but also a thorough understanding of the Massachusetts State Electrical Code.  Students will master wiring methods used in commercial, industrial and residential wiring, blueprint reading, operating principles of motors, transformers, photovoltaic systems and controlling circuits, as well as the Massachusetts State Electrical Code. This format allows students the opportunity to gain confidence while working as electrical apprentices during the day, and enhance their practical experience with focused, related instruction from a qualified instructor in the evenings and weekend. 


Graduates of MTI’s Electricity program will be prepared for entry into the Electrical skilled trades industry, including apprenticeship. This program includes 300 hours   towards the 600 required hours of classroom theory and up to 400 hours of work experience towards the Journeyman Electrician License.  Graduates also earn an OSHA 10-hour construction certification (Occupational Safety and Health Administration), Hot Work certification and a CPR, AED, and First Aid Certification.

The Electricity program is 10-Month 700-hour program, two (2) nights per week, six (6) hours per night, and Saturdays, 8 hours per week, for a total of twenty (20) hours per week. Students are also required to participate in online course work throughout the program.
