## Description

Reliance Controls 306CRK Pro/Tran-2 6 Circuit Transfer Switch Kit

Review: Wiring was very easy. Turn off the main breaker - I installed this about four weeks ago to work with my 6500 watt portable generator. Within two weeks we had a power outtage that lasted 90 minutes. I had the power on to the garage, refrigerator, heat, living room, master bedroom, and bathroom on in 10 minutes. My house is 3300 square feet and the load displayed on the transfer switch barely went up 1/4 of the way under normal use. It does jump to 1/2 way when running the heat or using the garage door opener. The hardest parts of my install were drilling through brick to mount the exterior plug and flush mounting the box in the drywall. If you weren't aware, you will need to buy a length of 10 gauge wire of whatever length you need to reach the exterior box. Mine was right outside so I bought 2 feet of wire for around $6. I also bought a flush mount kit for around $60 from a home store online. Wiring was very easy. Turn off the main breaker, remove the panel cover, pop out a breaker and replace the wire with the transfer switch wire, then twist tie the outgoing wire to the corresponding transfer switch wire. The wiring took around 20 minutes. My generator has the older style 240-volt outlet (apparently there are two styles of plugs). This kit includes a cord with the new style plug but also includes an adapter for the old style. To put the adapter on you have to cut the included 10 foot wire and attach the new plug. It was actually very easy, but made me uneasy to cut a brand new cable. So far I've recommended this transfer switch to four of my friends. Buy one, you won't regret it.
Review: Great product. Worth every penny. - Got the kit so we can use our 5000 w Coleman generator to power house in an emergency. I'm not a wiring professional but I understand the rules of electricity and am good at following instructions. One thing I really like about the Pro/Tran 2 is it uses standard circuit breakers. The previous comparable Reliance transfer switch uses proprietary buttons instead of standard breakers, The most difficult part was locating the transfer switch properly and wiring the outside plug. Also had to change the plug on the generator cord from 30 amp to 20 amp (20 amp plug was supplied). Get the outside plug wired into the transfer switch before connecting the switch to circuits in the breaker box. TURN OFF THE MASTER POWER SWITCH IN BREAKER BOX BEFORE MAKING CONNECTIONS. It's easier to configure each circuit if you remove the breaker from it's mount. Then it's easier to loosen the wire and connect the transfer switch wire. Always work one-handed if possible even if the master switch is off. Electricity is more likely to kill you if you use both hands. If you hit a live wire the electricity travels up one arm, through your chest a heart and exits through the other arm.. If you use one arm the circuit cannot be completed. Making the connections in the breaker box only took about 30 minutes, OBSERVATIONS: If you have converted your lights to LED turning them on hardly register on the transfer switch meters. If you are using a generator rather than an Inverter it might be wise to have surge suppressors on solid state stuff like TVs and computers. Generator electricity isn't as "clean" as inverter electricity. One of the circuits I wired to the transfer switch has a GFI (Ground Fault Interrupt) breaker. Normally you can switch a circuit to generator even if you are still getting regular line power. But if you try to switch over to generator on a GFI circuit when there's outside power, the GFI breaker will immediately pop. It works fine if there is no power coming in from regular lines. BUT remember if you are running in generator mode GFI no longer works unless you have a ghfi breaker in the transfer switch for that circuit. If none of the above makes sense to you, you probably should contact an electrician. Attached is a shot of the project with everything working --obviously there is some cosmetic work still to be done. Bottom line is that the Pro/Tran 2 is a great product for the price. If you live in an area prone to power interruptions this should be a must have.

### ⭐⭐⭐⭐⭐ Works great...
*by D***C on May 9, 2017*

Bought this kit to have my house wired the right way to use a portable generator in case of a power outage after the last blizzard this year. Thankfully, the power didn't go out but we had extended outages after the hurricanes a few years ago so this was something I've been meaning to do. This kit has basically everything you need to install except a length of 10/3 wire to run to the remote outlet outside. I had some laying around from a few years ago that I got at home depot. I did have an electrician friend help install this, but it probably isn't necessary if you are handy. There are good instructions, color-coded and labeled wiring, and basically you are just moving one wire from your main breaker panel and patching in a wire from this box for each circuit. You can switch over 6 110v circuits or 1 220 and 4 110s. I went with the 6 120s which pretty much covers the whole house. This unit allows you to switch back and forth from generator to line power almost seamlessly and also has meters at the top for each phase to see how much current is being drawn. Tech support from the company was also great as we had a little issue with the generator tripping a breaker that was due to neutral grounding and they were more than happy to send a free adapter plug for the cord with alternate wiring scheme to fix the problem.
