A main switch in the charging circuit risks introducing voltage drop and can damage the alternator if it is switched off while the engine is running.<\/p><p>We therefore recommend that any main switches be installed between the positive side of the service battery bank and the distribution block\/electrical panel.<\/p><p>Keep in mind that some equipment on board should not be connected through a main switch. For example, a heater, as it has its own shutdown procedure that must not be interrupted abruptly.<\/p><p>You may also not want the refrigerator on the main switch if you are only leaving the boat for a short period and want to keep food in the fridge.
