Questions & Answers

What happens if I start to draw more amps than the generator can handle?

Asked by: skibandit
If you purchased to load shedding modules for the Symphony transfer switch, you would be all set! They would shutdown less critical circuits such as bedroom outlets or whatever you set it up for! If you don't have them, well, you are out of luck. It will shutdown. You have to manually turn off appliances or curcuit breakers and restart it.

What is the typical propane consumption (per hour)?

Asked by: mammy

During very cold condition -25F, I eared that liquid propane may create water and freeze the combustion system. Is-it right? Do you have an option for solving this problem? 

Asked by: pierreb
I work for a propane company and we sometimes inject methanol into the tank to neutralize the water problem.

I have a cold weather kit 6030A that was listed for the model 40517 generator. Says to remove the drain plug and replace with the heating element. I have a drain hose there and the element doesn't fit. There is another plug just in front of it. There?

Asked by: Anduril
It should go in the place of the drain plug next to the oil drain hose. The oil warmer has slightly different threads then the plug itself. It will cut its own threads into the engine block when tightened down. Be careful not to tighten it too much (just a couple threads) as the threads are tapered and could cause stress cracks if over tightened.

Briggs & Stratton 12,000-Watt Automatic Air-Cooled Standby Generator is rated 4.5 out of 5 by 30.
Rated 5 out of 5 by from Does exactly what a great generator should do! Every power out was handled perfectly by our B&S generator. Our longest outage so far has been 72 hours and our lives didn't change one bit from being normal. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from After 1 yr. and it's 1st service. We had this unit installed for just over 1yr now and it has run it's weekly exerciser without fault. This unit has the cold weather kit installed and it started up without any problem at 6 degrees below 0 on a very cold morning. Service just completed by our installer, oil & filter were changed ( air filter checked - looked brand new ) unit was load tested with A/C & electric dryer on and passed without any trouble codes. My only advise would be to pick your site for the unit with the thought of what the very hot exhaust will do to a lawn. We had 6" of stone placed around the cement pad, for ease of cutting the lawn, however we had to extend that distance to 18" on the exhaust side because of the heat damage to the grass.

Rated 5 out of 5 by from Very happy with Purchase Bought and installed about 8 months ago. Went with a whole house generator. We lose power maybe once every couple of years and generally lasts about a day. About a month after it was installed I lost power for 3 days and the generator worked perfectly. Very happy with installation and footprint. These are noisy so make sure your placement is appropriate. Very happy with our installer also, crew did a very clean install and were very knowledgeable about B&S products. I was concerned about it handling our A/C unit on top of everything else but they were able to easily spare it out so it wasn't part of the load. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from LIVING IN THE COUNTRY IS GREAT, BUT WINDSTORMS AND NORTHERN ONTARIO WINTERS CAN VERY OFTEN TOPPLE TREES ONTO HYDRO LINES AND WE CAN BE WITHOUT HYDRO FOR DAYS. THE LAST INCIDENT LEFT US WITHOUT HYDRO FOR A DAY AND HALF. I WAS AWAY AT THE TIME, AND WHEN I RETURNED, DECIDED THEN AND THERE THAT IT WAS TIME TO GET A STANDBY GENERATOR. I MADE THE PURCHASE , HAD IT INSTALLED, AND WONDERED WHY I DID NOT DO IT LONG AGO. WE LOST HYDRO AFTER I BOUGHT IT, BUT THE GENERATOR TOOK OVER UNTIL THE HYDRO WAS BACK ON AND SAVED US A LOT OF GRIEF. WITHOUT IT, WE WOULD HAVE NO HEAT, NO RUNNING WATER AND QUITE POSSIBLY LOSE EVERYTHING IN THE FREEZER, WHICH WE HAVE ALREADY EXPERIENCED. I ALSO LIKE THE FACT THAT THE GENERATOR COMES ON AND RUNS FOR ABOUT 10 MINUTES ONCE A WEEK SO WE KNOW THAT IT IS READY WHEN NEEDED. I HIGHLY RECOMEND THE BRIGGS AND STRATTON STANDBY GENERERATOR. YOU JUST NEVER KNOW WHEN YOU MAY NEED IT.

Rated 5 out of 5 by from Evolution in Standby Generators Installers have finally finished the Symphony II Transfer Switch to my 12KW B&S Standby Generator. Electrician is stunned at the cleverness of this system - easy to install and whole house (using modules) service! My wife and I are thrilled and can hardly wait for a power outage!

Rated 5 out of 5 by from awesome I bought this 3 years ago, always nice to know when the power goes off I have lights in about 15 to 20 seconds. Running natural gas is the best. My only complaint is just a couple of months after my purchase they started gving a 10 year warranty, I only have 6 years. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Very reliable Very small footprint compared to other brands but more difficult to access the filters and other normal maintenance requirements. The ability to connect to my NG service was extremely important. [This review was collected as part of a promotion.]

Rated 1 out of 5 by from didn't have all the parts necessary to operate I installed the generator last weekend and didn't receive all the necessary parts with the generator to finish the job. It was missing the 2 pin connector harness to operate the generator on LP fuel.
