Voted Best Engineering Firm in Central PA

IETC was voted the winner for Best Engineering Firm in the recent Central Penn Business Journal’s 2018 Reader Rankings.

IETC is honored to be recognized by their clients and the community as Central PA’s Best Engineering Firm and thanks everyone who participated in the voting.

IETC services industrial and commercial customers in PA, Maryland, Delaware and New Jersey areas. Some of our electrical services are listed below:

•Infrared thermography testing
•Ultrasonic testing
•Electrical Engineering
•Maintenance & electrical testing of substations, high voltage equipment, circuit breakers, cables, transformers
•Service & Installation of power equipment including switchboards, used and new transformers, new and reconditioned circuit breakers
•Engineer/Construct & Design-Build



An employer is responsible to implement and document an electrical safety program.  Work place safety should come first for every industrial and commercial facility.  IETC can help by implementing NFPA 70E “Standard for Electrical Safety in the Work Place” by working with facility owners.  ECM Magazine recently posted in their frequently asked questions, answer section, “There is an OSHA letter of interpretation which says that OSHA doesn’t enforce NFPA 70E.  However, if you are compliant with 70E, you are compliant with OSHA”.  Compliance takes preparation.  IETC is an industry leader in electrical safety and electrical testing.

We can help you with the following:

  1. Identify hazards
  2. Assess risks with detailed engineering study to calculate safe PPE for your facility
  3. Implement risk control with labels, mitigation, PPE and provide safety training

Cable Testing

Prevent power outages with Cable Testing

Whether it’d be new cable installation or fixing an existing cable, cable testing is an integral part of the process to ensure a safe and correct installation.

Why is Cable Testing important?

Cable testing provides assurance that the new or repaired cables are able to deliver the necessary amount of power to the appropriate area without interruptions. Not only can cable testing tell you what happen to a failed cable but it can also be a preventative measure to predict a cable failure before it happens. Routine check-ups to a power source can be a great way to save money on costly repairs and possible severe damage.

“How can you avoid an unplanned outage?”

We’ve created a case study of a recent project that used cable testing to prevent cable failure. Also included in our case study is a section on infrared thermography scan and how it can help prevent potential damage to your power infrastructure of your building.

IR Scan

We identified a hot spot using an Infrared Thermography Scan on a 3000A 480V switchboard switch and experienced, investigative techniques.

We replaced the section of the switchboard before it failed.

Note: Metal blistering and signs of severe overheating. 

Contact points burned up.  This could have been a disaster waiting to happen if it were left to continue.
