Q: Is it possible to install the B&S 12 KW Generator #040326 on a slopping concrete pad? Is there a bottom steel frame with the option of adding leveling pads? I need to keep the generator off of the concrete for drainage purposes.
by Craig Barry from Virginia on October 08, 2013

A: Thank you for your inquiry....

All home standby systems need to be installed on a level surface. The Briggs units have a steel base but it is not solid so leveling pads may not work or may be difficult to set up. A level solid concrete pad is the recommended form.

I Feel Better
This is my first large generator, and the 18 wheeler delivered it on time. I was wondering about unloading it into the back of my Chevy Truck. The tail gate lift worked great and the generator was in good shape. After the driver and I unloaded the generator into my truck I took the generator home.

I had a 2x6 set up to lift her off my truck, with the generator being at that point 605 pounds. I used a wide strap and looped it through the crate it was in, and lifted it up off my truck bed-... more

Buying New...
The generator is just what we needed for a smaller house. But, we made a mistake. We bought a brand new generator to replace an older 7KW that we wore out.

We didn't buy a new switch since the switch was specifically designed for the Briggs generators up to 15kw. The first time the power went out the generator ran for 30 minutes then shutdown due to an under voltage fault.

It took the electrician several trips out and phone calls too numerous to count before they tracked down the... more
