Too many standby and back-up generator suppliers and installers don’t take time to properly measure and calculate the electrical load for your home, prior to sizing and recommending a generator.
Instead of getting it right, they under-estimate and under-size their customers’ generators. Which is kind of like buying a ticket halfway to Europe.
Where do they go wrong? They start by using the WRONG way to size a generator in the first place. Or in some cases, not sizing at all, just thowing out a number, like 20KW, and calling it good enough — thereby forcing you to either pay for size you don’t really need, or worse, putting your home at risk by trying to “get by” on a too small generator for the load you’ll place on it.
The point is that there is a right way and a wrong way to size a generator.
The wrong way is to simply come out to your house, pull a load measurement (or do nothing at all except “look around”), and call it good. If a generator company or installer does this at your house, Do NOT Hire Them!
Not only is this an unsafe practice that will usually lead to an under-sized, too small generator estimate, but it’s against code.
The National Electrical Code specifies only one correct way to calculate your home’s electric load: performing an NEC Load Calculation. The important thing is to ensure the generator can handle all of the simultaneous loads that might be placed on it at any given time.
We know that because Generator Power Systems is a division of Fish Electric, and Jim Fish is a master electrician who insists on doing things the right way. Which is to say the safe and dependable way.
So while we’re happy to provide you a nifty online tool for calculating a ballpark generator size, the truth is that actual power requirements have to be calculated by a knowledgeable electrician while on site. Or at least over the phone while you’re on site and gathering the correct load information.
Because having a generator that works when you need it starts by sizing the generator correctly to begin with. And we are nothing if not fanatical about ensuring that your standby power system works when you need it.
