What's wrong?
The Square D QO Plug-On Neutral Load Center in these 2019-2022 E-One Cyclone Ii, Typhoon, Typhoon N, Cyclone N, Quest Ii, and Commercial fire trucks is the electrical panel for the truck's installed circuits. It holds breakers and neutral connections so electrical current has a controlled path through the load center and back through the system.
On affected trucks, the neutral screw connection inside the load center is loose. A loose neutral connection creates extra resistance at the connection point. As current moves through that weak connection, heat builds in the breaker box instead of flowing through a tight, stable electrical path. E-One traced the issue to certain Square D load centers installed on vehicles, while validated inventory is marked with a green dot and excluded from the recall.
There is no warning sign before failure. The load center can overheat without a prior smell, warning light, or visible electrical symptom for the crew to catch first.
