Preventive Maintenance Auto Transfer Switch

The REASON for the recall was because the OEM's did NOT correctly torque the mount screws for the heavy 120 wiring. When I do a replacement on a Transfer switch and it has screws, I torque down the first time and let sit for 10 minutes to allow the individual wires to collapse and then retorque. You would be amazed at how much extra the 2nd torque will allow the screws to turn. ALL burnt/fire related damage I have ALWAYS seen was NOT on the transfer relay's but on the Connection screws on the buss. They were loose after a period of time because they were not torqued correctly at build. AND, TRANSFERRING POWER WITH LOADS WILL CAUSE THOSE LOOSE CONNECTIONS TO HEAT UP AND BURN THRU FASTER. THAT IS WHY YOU NEVER TRANSFER UNDER LOAD, TO HELP PROTECT YOUR SYSTEM. Maintenance would mean you retorque the wire mount screws a few times and check for tight connections. Doug
