## Questions & Answers

**Q: Does it come in white or ivory?**
A: I always find in brown but check online..i think yes

**Q: Can this be used to switch between two nema 14-30 outlets (indoor dryer and outdoor RV hookup)?**
A: This is a 3 pole switch which switches the hot wires only.

**Q: Is this 30 amp per pole or 30 amp total? Using it in a 3 phase circuit.**
A: as I understand it .
,it is 30 amp. total .

**Q: What kind of breaker do you use with it**
A: You need a three pole breaker.  Three phases with the amperage based on the load your using it for. I'm using mine as a 1hp motor starter. In addition I have an emergency cut off box next to the unit I'm running.  Switches work great for three phase operation I would highly recommend them.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Greate for mini-split indoor unit cutoff
*by A***C on January 26, 2013*

My Mitusubishi mini-split Heat pumps I just installed have the main power (20Amp) supplied to the outdoor unit. The power and control wires and ground (4 wires total), needed a 3 pole switch to allow each indoor unit to have power cut individually (to meet code). These are the only 3-pole on/off switches I could find and seem to be good quality, but are kind of pricey. If you want to install to code these are likely your only choice. Amazon had by far the best price on them. I installed these in the wall (with normal old-work boxes) next to each unit. Worked great. Just what I needed. Used a standard switch plate. I used the 14g 4-wire cable available from eComfort where I got my mini-split units. The wire supplies power from the outdoor unit into the indoor units though the switches.

### ⭐⭐⭐⭐⭐ Item works as it should
*by F***M on January 22, 2019*

No problems with this switch. This is by far the cheapest way to turn on and off 480 Volts. There are so many restrictions for high voltage equipment and using alternative contactors and other devices are 10X more expensive.Will definitely buy this again if the need arises.

### ⭐⭐⭐⭐⭐ great
*by S***A on August 13, 2024*

The product was delivered quickly and in excellent condition. Thank you!
