Equipment intended to be powered by the receptacle needs to account for intermittent contact, and voltages outside the nominal 12 V DC like top voltage 9-16 V continuously, top voltage at 20 V during 1 hour, 24 V during 1 minute, 40 V during 400 ms.
Protection component tolerance example ratings are +50 to -60 V DC[11] Additionally, issues can occur with temperatures varying between -40 till +85 °C such as humidity and condensation.
