Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
Should the step circuit be overloaded, the breaker may not trip as intended, increasing the risk of a fire.
Thor Motor Coach (TMC) is recalling certain 2017 Quantum KM24 motorhomes.
The power supply wire for the steps was incorrectly attached to a 50 amp circuit breaker instead of being connected to a 20 amp circuit breaker.
