Transfer Switch Maintainence

Reading the latest copy of Motorhome magazine, I came across an article about Winnebago's recall on transfer switch connection tightness. Having been an elevator technician in my working life, it had been beaten into my consciousness to tighten electrical connections on large relays once a year. As a matter of course, I tighten the terminals annually on our motorhome's transfer switch and always find at least one that has slightly loosened from either vibration (the relays come in with a bang!) or just expansion and contraction of the wires from heat. It's a very important thing to check as a loose connection can cause heat buildup and damage to the terminal or ruin the complete transfer relay. Make it a point to check them..just be sure to unhook from shore power and have the generator and inverter off when you do it!
