## Customer Reviews

### ⭐⭐⭐⭐⭐ Switch connection drawings have a serious error in them if you get a 220VAC switch.
*by J***Y on October 6, 2024*

I have the JOTTA JTQ3-100 here on my work table. It's the 3-line xfer sw. Says that 'control voltage' is 220 VAC but the conn drawing provided with the unit (and in the figures above on the amazon sales page) shows it wired for 110V operation. That is one side of the line goes to AR or BR, that's OK but the the AN and BN wires are tied to neutral, that is the center tap on the xfmr out on the pole. For 220V operation it should go to the other line, the other side of the xfmr not to the neutral line.I opened the unit up and applied 110VAC thru a diode bridge directly to either of the actuating coils inside (they main actuating coils want at least full-wave rectified AC) and it would reliably snap back and forth at 110VAC tho not as vigorously as at 220VAC.I note that there is a 220VAC (NNC68BP-4Z) coil relay in there wired to give the A connection preferential control over connecting its side to the load. This relay will not pull in on 110VAC so that's what makes it a 220VAC control unit.I'm saying the unit is indeed a 220VAC control unit, 220VAC is required to operate the unit, but the wiring diagram provided with the 220vac unit (and the diagrams on the sales page) shows it wired to operate from 110VAC. JOTTA must fix this diagram to show correct connection. It's confusing everyone who buys it!It's an excellent design, very safe, very fast, very reliable. Everyone who wants an ATS should get it. But JOTTA needs to fix their documentation!Correct me if I'm wrong.

### ⭐⭐⭐⭐⭐ Will Not Work With 110-120v Main Power!!!!!!!
*by H***N on February 19, 2024*

The unit is extremely simple. Mostly mechanical units on the inside. Couple diodes, plunger solenoids, switches and a couple LEDs.I hooked the unit up and it would default to the secondary powers side. Manually switching to the shore power side worked fine.When plugging into shore power, the device would hum. No smoke, nothing burned. Nothing had failed.When auto mode was enabled, the device would immediately switch to the secondary powers side and the only way to get it to go to the shore powers side was by manually cranking the knob to that side where it would start to hum.I beat my head against the problem for way to long. Decided to return as defective as another user left a review with the same exact issue that I had. Did a little more looking and found out there isn't enough power on a 110-120v system to trip the main relay to transfer the power to the shore power side of the unit. The hum was from the min relay not having enough power to activate to be able to switch the plunger solenoids.These units are cheap but built simply. I don't see how the device could be unsafe just because of how simple it is.Sadly, I am unable to find a 2 pole 110v switch like this so I ordered the 3 pole 110v version and found a 2 pole version on ebay for $24.48 including tax and shipping.I will be putting this in my camper to run the outlets of an inverter.Testing the device by manually turning the nob results in a huge clunk with zero, noticable, delay in power transfer.I'm not sure why there are so many 220v versions of this switch marketed to US users. Learn from my mistakes.
