Do’s Of Plugging In

Subscribe to DIY Boat Owner’s newlsetter in order to know when to turn off the boat’s main AC breaker before plugging in.
“There are two reasons for turning off the boat’s main breaker before plugging or unplugging the shorepower cord. The process of plugging in or unplugging the shorepower cord can cause spiking noise, harmful to sensitive electronics. More importantly, you can confirm AC polarity before connecting to shorepower. An AC polarity indicator, which all boats equipped with AC power should have, ensures that the hot and ground wires aren’t switched.”
