Q: What is the proper procedure to follow when switching from Line power to generator power. Do you have to use the Main diconnect switch first?
by Leonard Chimienti from New York on September 16, 2013

A: Thank you for your interest in Electric Generators Direct!

The proper procedure for transferring from Generator to Line power is as follows;

1. Plug the female connector of the generator power cord into the power inlet box or the
power inlet on the transfer switch. All circuit selector switches on the transfer switch
should be in the LINE or OFF position.

2. Insert the male plug of the power cord into the outlet on the generator.

3. Start the generator outdoors. Follow the procedures described in the generator
owner's manual furnished by the manufacturer of the generator.

4. Select the circuits to be powered by the generator by moving the corresponding
switches on the transfer switch to the GEN position. Use only necessary household
items when under generator power.

5. Alternate use of larger loads (furnace motors, well pumps, refrigerators, etc.) to
balance the load. See "Balancing the load" on page 4. Do not exceed the maximum
wattage of the transfer switch.

6. Some circuits are limited by the transfer switch circuit breaker to a maximum of 15
amps when switched to the GEN position. If you have switched on a circuit selector
switch on such a 15-amp circuit to the GEN position that normally draws more than 15
amps, turn off some of the appliances on that circuit to avoid exceeding the 15-amp
load for that circuit.

7. Test your circuits by using the watt meters on the transfer switch or determine wattage
from the nameplate on each appliance or motor.

8. Models 15114A, 30114A, and all suffix "B" Models except the 8-circuit Models do not
have watt meters. See the note below for additional information on these models.

9. Make a note of any excessive loads. These loads must be turned off during
generator operation.
by Mike, Product Expert
Q: What size transfer station do I need with a 8000 watt generator. We have a well, refrigerator, electric hot water heater and in the winter run a wood boiler that also supplies our hot water so the hot H20 heater is shut down. I am thinking of purchasing the B&S model you recommend?
by Barbara Davis from New York on August 30, 2011

A: You will typically size the transfer switch to match the largest outlet on the generator for proper connections. A 8000 watt generator will normally have a 30A 4-prong 120/240V type outlet so all of the 120/240V 30A transfer switches will work great when connected. The Reliance Controls 30310A is a perfect fit for any generator with a 30A 4-Prong 120/240V outlet.

This a replacement for an old Generac transfer switch. Hands down this Reliance is a much better made product. I have recommended to friends in the past. Great manual switch.

2nd One I've Purchased
I purchased one unit and had it installed on my previous home, I moved and had another installed on my second home.

It is a great transfer switch. The first one had no installation problems. The second one had a misplaced black wire that connects to the generator plug. Had to call the mgf. 2 times finally was told to remove the face panels and locate it. I did and there it was.

Tansfer Switch Review
Received it from Generators Direct, and the box was damaged, and unit had a small dent in it. Had a professional electrician install the transfer switch. One circuit does not work, and the wattage meters do not work. Have had a call in to the mfg for several weeks, and have not heard back yet regarding having the parts replaced under warranty. Needless to say, I will have to pay to have my electrician come back and replace the parts, if I ever hear back from the manufacturer. Very... more

Super Easy To Operate
I bought this unit a couple of months before Sandy visited NJ. Hardwired the power feed from my detached garage into the house. I installed connections to the six 120 V circuits for my kitchen, dining room, refrigerator, washer & dryer, kid's room, and hot water heater. Still have the two 240 V for future connections to sump pump (being added to house), AHU and compressor (if desired).

Two months passed and the storm hits. Super easy to operate the panel. Keep a flashlight handy (I keep... more

Easy To Install - Works Great
I got the Generac Generator last year after two outages convinced me it was time. I tempted fate by simply putting it in the garage without testing it.

I ordered the transfer switch the morning before Hurricane Sandy hit. Well, Sandy hit that night and knocked out the power. The next morning I put the supplied oil in the generator, filled the tank and started it up in two or three pulls. The generator worked great but only powered the refrigerator, a bunch of lights, and the TV via... more

The customer was satisfied with the two transfer switches, it services their purpose for the present.This is not the first switch that I installed. Your prices were compatible with the local supply house, but you were able to get it to me faster.

High Quality, Easy To Install Switch
I received my first transfer switch and two of the breakers must have broken during shipping. www.electricgeneratorsdirect.com was very quick to have FedEx pickup the damaged unit at my house and ship a new one. The install was so simple it actually took me more time to properly label my panel and select the circuits I want to run than it did to install the unit. I have my well, furnace, fridge, microwave and almost every light / outlet in the house powered. I bought this after Sandy left... more

Transfer Switch 30310a
The only complaint that I had was that the 1st 15amp circuit (A) did not function, especially when I had the furnace wired to it.
My electrician opened up the transfer switch, and found that the circuit breaker button was broken in the inside of the box, and was
in the tripped position.

Called reliance, waited on hold for approx 30 minutes explained the story, and they will send out a new 15amp
breaker. Other then that, all was fine.

No Power Interruptions
Having an October snow storm which devastated the east coast this year, with many people losing power for more than a week is no fun.We also had a hurricane come through a month earlier which had some people without power for a week also
With this in mind I decided that I was not going through this again.
