When thinking of safety the possibility of auto start with no one at home is often overlooked.
A local family lost their home when the genset started automatically... the flames spread from the wooden structure and because the home was partially hidden, flames spread to the home.
Rodents had built a nest and the family was away for Thanksgiving when a branch took out power to their home.
A truly automatic system is just that... it will start and run until it can't, someone manually turns off the power or power is restored.
there is no cheap way haha. i have a program from generac to calc generator loads. its part of my powerplay software. i use it when i size my jobs.
If theres elect heaters...theres always problems. When i get houses with electric backup heaters and or electric water boilers, i always need to shed those loads....unless i go big.
i reciently hooked up a 45KW unit on a house with electric heat, elect backup heat, elect water heaters and heat pumps. took some doing. It works great though. On this application, he had 2 x 200 amp panels so i installed 2 x 200 amp transfer switches and joined the feeds together in 16x16 J box with single 200 amp feed to generator.

care has to be taken to link both switches EXACTLY the same. i use color coded wires .... it gets confusing at times.

one of the real downsides of a portable gen is how to run in the pouring rain or blowing snow when you don't have a convenient overhang to park it under. I won't even run mine in my garage with the doors open. Never know where that CO2 will wind up; always run it outside, at my last house under the totally open front entrance porch. At this home, I don't know yet, will have to be out the garage back door, which then gives my extension cords a straight shot into the kitchen.
So what happens when a gas powered generator is operated outside in the pouring rain for several hours?

Good question.... I've always run mine in our unattached shed with the door open. I ran it in my in-laws in a yard barn with the door open. I guess that's something that needs to be planned for before it happens. If its pouring rain, you probably shouldn't be messing with a generator anyway. Good way to get whacked. :shocked:
It is a necessary safe practice to ground every generator well. All have a grounding lug and I have driven two 8' electrical ground rods and connected a braided copper wire to the grounds with copper connectors and then to the generator lug. This must be done to insure that all the connected loads are grounded and safe.
I've wondered about this because I have a truck mounted unit that I use for grinders and drain rooter machines... the generator is bolted to the truck... the truck sits on tires... nothing is driving into the ground.
Yeah, makes you wonder about all those portable generator/welder sets you see on service trucks. Does anyone really ground them?![]()

my error, meant CO"1"...CO2 is a minor hazard compared to how lethal CO is.
Getting back to the original question, what is the best standby generator? I see a lot of people here with Generac/guardian generators, but when I was buying mine I was told to stay away from them because they're not reliable. What have your experiences been?
