What is the Normal Temperature of Splitvolt Splitter Switch

A Splitvolt splitter switch is rated for an ambient temperature of -20°C to 50°C (-4°F to 120°F).

At idle, when not using the dryer or charging, it should be slightly warmer than the ambient temperature at the corner near the LED. Rest of the unit will be at ambient temperature.

Its temperature will increase during a charge, eventually get to a maximum temperature after about 2hrs of charge. It can get fairly warm in the summer, especially when its over 100°F ambient. However it shouldn’t get burning hot, or any hotter than the EVSE’s control box at the same time.

We recommend customers to reduce charging to 20 amps or less when the ambient temperature is over 100°F, or wait to charge at night time when the environment cools down, for maximum life span of the unit.

We also recommend customers to check the temperature of every connection point (at every plug and socket) every few months to make sure they do not feel exceptionally hot, which could indicate a loose wiring. Loose wiring can cause electricity to arc, generating lots of heat which can melt or burn the socket/plug. Remember, charging your car is stressing your dryer circuit to the max, and many customer’s dryer circuit has not been inspected or maintained for years/decades. This can leads to loose wiring over time.
