Plastic Electrical Panels? Plastic & Electricity?

On occasion, I come across the Unicorn of electrical panels – the Trilliant model plastic electrical panel.

I have talked to numerous master electricians in New Hampshire that have never even seen one of these panels, yet I’ve come across 4 – 5 now in my time as a home inspector.

Now, even if you’re not an electrician, if the idea of a plastic electrical panel seems odd to you, you are not alone in your thinking.

This type of panel was manufactured for only a short amount of time, and was not widely disseminated throughout the United States.

The reason for this, was that electricians generally viewed this type of panel as potentially flawed, and as a result, plastic electrical panels were never welcomed into the industry.

After a short manufacturing stint, the technology was abandoned.

The manufacturer for the panels that I’ve encountered was Square D – one of the most well known and respected names in Electrical Panels in the United States. The model name was Trilliant.

This model of panel was manufactured between the years of 1990 – 1996 by Square D.

Interestingly enough, plastic electrical panels were welcomed with open arms in Europe, but here in the United States, they were met with serious skepticism by most electricians, and as a result were not widely adopted in any area of the U.S.

Because of the skepticism, Trilliant panels and other types of plastic electrical panels (which apparently there were others), were effectively phased out of use here in the States.

There were no known major deficiencies that were associated with plastic electrical panels. But a byproduct of the panels not being adopted for use here in the U.S., was that the circuit breakers and other components of the panels are very expensive to replace.

The only know potential issue with the panel is an issue with the surge protectors that were designed for use in the panels. The surge protectors were recalled in 1995.

The plastic screws that hold the “dead front cover” in place are very difficult to operate and can be easily broken. And of course, the screws are very hard to replace if you do break them. And if you lose enough screws, you have an unsecured panel cover.

I can tell you from experience, that the covers are a pain in the butt to take off. But we take them off never-the-less!

At First Choice Home Inspection, our experience gives you piece of mind!

    From the moment I reached out to schedule my inspection I was impressed. I received a return call within 24 hours and was able to have my inspection next day due to cancellations caused by weather. Mike was prompt, professional, and incredibly helpful.He took the time to explain his process and answered all my questions with patience and clarity. It was evident he had a wealth of knowledge and experience in the field.The inspection report was detailed and easy to understand.Overall, I couldn't be more satisfied with the service I received. The professionalism, expertise, and customer care demonstrated exceeded my expectations. I would highly recommend their services to anyone in need of a thorough and reliable home inspection.

    John was immensely helpful, educational, and thorough. Giving us answers for every question we had, plus he went through all the basic functions of the house he was inspecting so we would know how to properly use the appliances and things like the water heater and furnace. On top of that he was punctual and thorough pointing out the most minute issues and helping us be aware of why they’re a problem. We will likely never use a different inspecting company as this was such an outstanding job.

    Mike is very thorough and honest. When moving to another state, you really rely on word of mouth as to who you can trust. Our Realtor highly recommended Mike and she was spot-on. The first house he inspected for us fell through, so we called him for the second one! My fiancé really liked working with him during the inspections. Thank you MIKE!

    Highly recommend First Choice Home inspection! Mike was wonderful to work with, explained everything and was very thorough. He cleaned off snow from the roof and climbed up to evaluate the roof. In my experience, a lot of other home inspectors are not willing to go up on roofs. He found an issue with my well that would have been a costly repair for me post my home purchase. So I am very grateful that was found prior to closing.
