Reliance Controls30310A Pro/Tran 10-Circuit 30-Amp Indoor Generator Transfer Switch

I didn’t have a lot of room to install the transfer switch but I wanted more than six circuits. This was exactly what I needed. I like the load meters to balance the load.I have an industrial generator rated at 20 amp at 220V. I wired everything for 30amps in the house. I bought a 30 amp exterior plug to plug the generator into. This required an adapter for my 20 amp cord to plug into a 30 amp socket. You can find the adapter on Amazon.I tested it out and all worked well. Knock on wood, I haven’t had to use it yet.

Pre wired internally, decent instructions. Seems to be well made with good action on the switches.

Only negative thing I can say is that the meters only work sometimes

Some additional information that I hope is relevant. This is more about interfacing your generator than the transfer switch itself.The transfer switch works as advertised. Be sure to match the wattage output of your generator to the transfer switch. This switch will max out at about 3750 watts on EACH side. My generator has a max of about 4400 watts (120 volt - all to one side of the transfer switch) or 2200 watts (240 volts - with 2200 on both sides). If you use propane instead of gasoline (much cleaner burn) you will lose about 10 or 15 pct of your wattage.The transfer switch uses a L14 30 amp plug. Your generator MUST use the same plug. Many generators have the ability to switch between 120 and 240 volt mode. This will give you all the "juice" on one side of the transfer switch with "ZERO" on the other. With this thought you should probably be choosing a generator with an output between about 4000 and 8000 watts max. A 4000 watt generator will give your the max watts on one side of the transfer switch (in 120 volt mode) while an 8000 watt generator will give you the max watts on both sides of the transfer switch (in 240 volt mode)Quick example of 120 volt vs 240 volt. My microwave wont run in 240 volt mode on my 4000 watt generator. But it is fine in 120 volt mode. I had to flip the black and red wire in the plug of the transfer switch to get the microwave on the side with all the "juice". Then 'toggle" my generator between 120 and 240 mode when I don't need the microwave.This is a mild annoyance, but I got my generator for about $600. And it runs about 16 hrs on a tank of propane. I have to mix and match which breakers I use due to the "size" of the generator but for just over a grand (electrician installation included) I keep my house heated, food cold, microwave some food, some small appliances - coffee maker add toaster, TV, internet, and sufficient lights when there is an outage.Be aware that all portable generators require oil changes regularly (mine is about every 20 hours). Using your generator judicially (say 4 hr on 4 hr off) you can get about 2 days between oil changes. If you are thinking about propane - you cant store inside your house - not even your garage - but there are some nice vinyl propane tank covers for $20 on the web. U-Haul sells high quality propane tanks - ones with "gas gauge" and fills them. I bought my tank and got it filled for about $65. About $40 tank, $20 propane. Then bought a 2nd tank and cover.You should run your generator monthly and put a small load on it just to be sure that it is in working order. And you cant run your generator INSIDE either. No not even in your garage.GET AN ELECTRICIAN. Plan what you need against the power of your generator. Keep in mind any power loss due to propane or natural gas. After you wire up, dry run a few times until you are sure that you know how different items you will need to run react together.Even after you do all this you still might have to switch a few things around. Don't throw the pieces of cut off wire away. You might need them if you do have to make some changes.Of course if you buy some massive generator (7000 - 8000 watts) than ignore most of what I wrote. Except the get an electrician part.PS. my transfer switch had a defective "breaker". I called Reliance and they immediately sent one. Best to check them all first as it is easier to fix before you wire it up to your panel box.

This is a great product, well made and easy to install. I just went through hurricane Irma. It was delivered on time as I requested. I started installation as soon as I received it which was later in the day as promised. Not wanting to work after dark I wanted until morning to complete the installation. I ended up with one connection I wasn't sure about and contacted Reliance Customer Service. I spoke with a woman that knew exactly what i was talking about and explained how to deal with it. I completed this easy installation about 24 hours before Irma knocked out the power in South Florida. I started my generator energized the panel and everything worked perfectly. Power was restored 24 hours later by FPL. We had everything we needed for that period. My biggest mistake was waiting until the last minute to purchase this. Thank you for the way this was handled and how well this is made.Jack D...

I had installed a 6 circuit reliance transfer switch a few years ago. When we lost power in the winter I realized I did not place my boiler or air handler on the switch so I decided to upgrade to a 10 circuit since I had plenty of headroom on my firman generator. It installed very nice and worked like a champ

When I got the transfer switch, I immediately thought this was a mistake. A circuit breaker had broken in shipping. I sent an email directly to Reliance Controls because I didn't want to hassle with emails back and forth between R/C and Amazon for a warranty gig. Within 8 hours I had a response from R/C asking for a return address and they sent me one free of charge and I had it installed within 3 days. Also, I ordered a flush mounting kit it turned out great. Note: had to install a 2x4 filler onto stud to get the space between load panel and transfer switch and only one hole for access between the load panel and transfer switch. The instructions were a little vague at times but anyone with any mechanical experience can skate though it. I am very happy with my purchase and from order to complete install was 7 days. I recommend this unit highly. If I were to order another one day, I possibly would purchase the PRO 2 as the breakers look like a square D and more durable.

I received this in October 2021. Mounted it on wall and ran wires through conduit in January 2022. Started wiring last week (February) and discovered that I am missing one (1) set of wires. VERY POOR QUALITY CONTROL. Now, what do I do? The time to return this to Amazon has passed, plus I have already installed the unit and the 9 circuits. Who would have thought that quality control would let a unit pass that is missing a set of wires? So, now I have a 10-circuit unit that only has 9 circuits and I have to re-plan my wiring. Lessons learned: 1-never buy another Reliance Controls product and 2-check everything the moment you receive any product ordered from Amazon.

The transfer switch is great quality and was easy to install

First off this is CSA approved for Canada. The only thing you may have issues with is your local inspectors interpretation the Canadian Electrical code in regards to the wire nuts in the main panel if you can't easily create a junction box for the connections to this panel (the preferred way). In my area, these don't need a permit but need to be installed by a "licensed and bonded electrician". My electrician didn't have any issues with having the wire nuts in the main panel as it was an "existing install" and I would have ended up with "multiple" junction boxes. I had the electrician use "WAGO"s rather than wire nuts for a cleaner looking install.So now that's out of the way, all I can say is the unit is great and SUPER easy to install and follow since the wires have letters so you know what goes where. The two 20amp 240V can have the trip bar between them unscrewed creating 2 120V circuits. I used this as part of a 6000W 240V UPS inverter/charger + LiFePO battery setup as to back up a bunch of circuits to be instantly in the event of power outage (youtube has some great video's as to how to do this using this model specifically). Being able to put those circuits back in "Line" mode in the invent the inverter/charger fails is why I picked this unit. I've used this unit in another normal "generator" setup and it also worked well for that.

Installation was okay. I used a single pole 120 Volts generator, so the 2 poles of the Transfer SW had to be connected together at the inlet.Although the transfer switch is 120/240V, it does not really specify how to connect it when a single-pole generator is used for 120V, unless you pretend to use one single "row" of the Transfer.The breaker switches don't seem to be easy to serve/replace, although are parts offered by the manufacturer via resellers.The selector levers are very sensitive, so it is very easy to switch from GEN to LINE and vice versa, without letting you stay in the OFF position. So you need to be extra careful.the four 20 amps circuits are only allowed to be connected to 20 amps circuit, since when in GEN mode, the breakers of the Transfer Switch are the only protection of the home circuit and bypass the main panel breakers.You can connect 15 and 20 amps circuits to the 15 amps Transfer Switch positions, but only 20 amps to the 20 amps positions. In my case, only 6 15 amps circuits were possible to connect, so you would need to change the 20 amps Transfer Switch breakers to 15 amps if you pretend to use all the circuits in a single-pole 120Volts.

Tested few times during Power Outage.Works A+++. Easy set up.Very Satisfied
