Review: Great for Shore/Battery power switch! - Great switch, good price & worked perfectly for my application. The switching configuration gives many ways to hook this up and achieve a lot of switching combinations. I was using to switch my RV from batteries and solar power, to AC shore power. It's capable of handling the high amperage and can switch all legs (pos. & neg.). A word of caution: The switch is made to mount on a thin surface (maybe 1/8" at the most). To mount it on the 7/8" thick bulkhead in my RV, I had to make a shaft extension that could attach to the switch shaft & fit into the knob. Although you can find literally dozens of these in 1/4" sizes, there are none I could find ANYWHERE in the rediculous metric 6mm. Hence, had to custom make on the lathe. Also had to find longer metric screws. Just lettin' ya know.
Review: GOOD BEEFY Switch - I was installing a solar/inverter system in our RV and this box and the switch that goes inside it were required for the install. The box is perfect size, has knockouts in the right palces, has screw holes and the cover is made to match up with the rotary switch. The switch is beefy, solid terminals, good screws, nothing stripped out while I was installing. The switch turns into position with a soilid clack, seems sloid

## Questions & Answers

**Q: Just received the switch & it's sturdy but there are no instructions on how to wire for 2 power sources to one load. where do i get the instructions?**
A: Im going to use this switch to flip power between dryer and water heater 230v  2 phase . Hook up dryer to pin 1+ 5  main power in on 2 + 6, for pos 1-- also add  jumper to  2 + 4  and a jumper to 6+8 for pos 2  then add Water heater to 3+ 7 . This should work to flip power.

**Q: Anybody have a wiring diagram for this unit to connect a 240v 50a circuit? need a switch to change between feeding a 50a outlet and 50a piece of equip**
A: All the instructions come in Chinese with a very vague chart. You must be greatly intuitive to figure it out with a meter. Good luck I'm still trying.

**Q: It has a label that says 240v / 2.5a ith=63a. what does 2.5a mean?**
A: That’s strange, mine doesn’t say that. It should be 660 volts and 63amps. I have mine between 30amp shore power a 1500 w inverter for my RV

**Q: Can this be used to switch between two 50 amp outlets for charging an electric vehicles?**
A: Absolutely but I wouldn't push 50 through it.  I'm not sure what it's rated at but would easily do 30 A

### ⭐⭐⭐⭐⭐ works great for a custom shutoff switch
*by A***R on March 2, 2023*

I have my tesla nema 14-50 charger in a metal box but planned to upgrade to a dedicated tesla home charger (until they raised the price from $350 to $450!). Wanted to retain the option of using the 14-50 plug so customized the box with this switch to run both off the same circuit (but never at the same time). In the picture I have the 240v supply running to the back half of the switch with jumpers between bank (1/5/9) and bank (3/7/11). When the switch is in position 0, all contacts are disengaged in in the OFF position. When the switch is in position 1, bank (2/6/10) is energized and will eventually be connected to the breakers on the left which will run to the new Tesla home chargers. When the switch is in position 2, bank (4/8/12) is energized which is connected to the NEMA 14-50 outlet shown. The only thing I wish this came with is a cap or covers for prevent accidental contact with the exposed terminals. I have some electrical tape on it for now but will try to make something out of plastic. On the door, there is a dedicated power meter measuring how much power is being drawn at any given time.
