Technology Research (41260 Surge Guard 50 Amp Automatic Transfer Switch

Seems to be a slightly upgraded version of the Southwire 41260 automatic transfer switch and surge guard that was OEM on the coach.

Working perfectly now. Exact replacement unit made wiring up the new unit a snap. Take pics then just remove and replace. One thing that is different is this new unit has allen wrench head bolts that hold all the wires in place vs screwdriver head bolts on the old model. The specs call for 45 inch pounds of torque on the allen wrench heads so I went to Harbor Freight and bought a cheap inch pound torque wrench to ensure ALL the bolts were tightened to spec and equally. I was told by Tiffin that the new units have a new larger circuit board controller and mine did. The shore power relay got weak on my old unit and would chatter and that is the reason I had to replace the old one which was seven years old.

I had to replace this in a nine year old motorhome. I'd have expected it to last longer than that.

Amazon has the best price and fastest delivery for this part. Original lasted 6 years, and it’s a pain to install a new one! My husband is NOT handy, so we had an electrician install it. Now if the electricity provider would fix the grid here in Texas to stop the sudden outages and surges that damaged the original part, we should be ok with the new one for 5-6 years.

My utility had an extended low voltage condition and it burned up the input coil. My Motorhome went on the inverter and kept me powered up but there is only so much time it can do that. This product arrived with in 2days and the vendor must have known that I really needed it badly. 5 stars for them!

Product was installed and worked as expected

We have had this in our Van Leigh Vilano for a little over a year now and this unit has been great! We, at one point heard a humming noise out of the compartment it was installed in so checked the voltage input. Turns out low voltage at an RV resort was causing the unit to hum. Later on we had a loss of power even though the 50 amp breaker had not tripped. Called out an electrician and he found that a loose wire in the breaker box had caused one 4 gage wire to burn completely in two. Even thru all this our surge protector managed to save the electronics in our 5th wheel!

Easy DIY project of you are confident around electricity. One arm guy removed old one and installed the replacement. Easy peasy!
