These panels are not very common in the Phila./New Jersey area. I’ve been a Union Electrician for 17 years, and today’s inspection was the first time I’ve come across one.
After some research I’ve found that they were common in the early 90’s but their popularity never really took off. The only issue with these panels that I could find was with an install able surge protector that was recalled in 1995. Other then being discontinued and replacement parts being expensive and hard to find, does anyone know of any other issues with them? Were they more popular in other parts of the country?
