Zinsco Electrical Panel Overheating Photographs
- POST a QUESTION or COMMENT about where overheating occurs in Zinsco electrical panels & breakers: Field failure report indicates severe failures of Zinsco electrical panels / circuit breakers
Here we provide field failure photographs of overheating (and non-tripping) in a Zinsco electrical panel. This website discusses the electrical, fire, and shock hazards associated with Zinsco electrical components, circuit breakers, electrical panels, including certain Sylvania electrical panels and breakers which are in fact of the same product design and origin.
Our page top infrared photo of an overheating Zinsco electrical panel main circuit breaker (left hand white-colored [hot] circuit breaker in the lowest pair in the photo above) as well as other Zinsco overheat photographs in this article were provided by Florida home inspector Jon Bolton.InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website.
Zinsco Electrical Panel Failure Report - This Field Failure Report Includes Infrared Photographs of Overheating Zinsco Circuit Breaker/Panel Components
Zinsco Main No-Trip, wire burn-up report provided by Jon Bolton, a professional home inspector (The Inspectagator) in central Florida (see photo at left).
Notice the burned wires connected to the bottom double-pole Zinsco circuit breaker? Mr. Bolton wrote:
I have done 2 inspections in this complex, ironically (or not) both had issues. One had a complete side blow out. Sent a letter to management, no response, hmm.
Our photographs (below) provided by Mr. Bolton, show both normal transmitted light images and infrared images of overheated components in Zinsco electrical panel. With the two Zinsco photos side by side, you can see that the discolored Zinsco bus at lower left in the first photo (below left) is overheating in the IR photo taken at the same time (below right). There is more going on than just what shows here (continue below).
Our photographs (below) show both normal transmitted light images and infrared images of an overheated main circuit breaker - the left-hand Zinsco circuit breaker in the pair.
Our photographs (below) show both normal transmitted light images and infrared images of overheating in the side of the lowest, left Zinsco circuit breaker mounted in this electrical panel. This is the same area where other field photographs show actual melting or circuit breaker molded case-blow-out in some circuit breakers.
