What consequence can arise from poor connections in Zinsco electrical panels?

Poor connections in Zinsco electrical panels can lead to potential fire hazards due to several factors. Zinsco panels are known for their problematic design, where the breaker connections can corrode and create insufficient contact. This results in increased resistance at the connection points, which leads to overheating. When the connections heat up excessively, it can ignite surrounding materials, leading to a fire.

In addition, these panels are also more prone to arcing, which contributes further to fire risks. Given that electricity generates heat, if the connections do not conduct effectively, the heat builds up. Therefore, the consequence of having poor connections in Zinsco panels is a significant fire hazard, which is a critical safety concern for homeowners and electricians alike.
