For sale are 19 Taylor Electric "Cirkit Guard" Type Q circuit breakers. These were made in London Ontario, Canada in the late 1960s and were installed in my home in 1967 when it was built. They function properly. I needed to change my entire panel when I bought my electric car. At one point several years ago I needed to purchase a 60 Amp fuse, and it was really hard to find these circuits breakers. I paid 100$ for the breaker because at the time it was still significantly less than changing the whole panel. If you need an additional breaker, this could save you significant money, if you have this panel in your home. I have several other circuit breakers for sale on eBay with different amperage ratings, in case you need it. Please contact me with any questions, and I will try to respond in a timely manner.
