I have an older model Grizzly hybrid tablesaw wired for 110v. Unfortunately my shop is not wired for 30amps, and I have been quoted $1800 to get it wired properly. My question is this: can my tablesaw be run from a generator?

Sure , why not.
Make sure its sized accordingly for startup amp draw.

Can you handle 220 volts? The amperage draw would be a lot less.

The Grizzly Hybred G0177Z can be wired for 20amp 120v, or 15amp 240v. The Grizzly Hybred G0833P can be wired for 16amp 110v, or 8amp 230v. What model do you have. What does the manual say. If you call the Grizzly 1-800-523-4777 and ask the salesman for a service rep, they’ll switch you over. They can give you answers.

You can run anything from a big enough generator but good luck finding a cheap generator that will handle 30 amps!

Tough predicament: Generator big enough to run a 20A (30A peak) 120V saw will be almost as much as cost quoted by electrician.

Couple of suggestions:
1) Change saw over to 240V.
Just about any solution to get more power in shop will be easier with 20A 240V circuit, then a 30A 120V circuit; regardless of whether using a generator, or adding new 240V outlet in shop. 30A circuit requires 10 AWG wire and that stuff is significantly more expensive than 12 AWG required for 20A. 30A plugs/receptacles are also 1.5X more.

2) After you convert the saw to 240V, make a 12/3 extension cord with dryer plug on end and run cord inside to laundry room (which is usually next to garage). Wife can live without dryer when you need saw. 12/3 SO rubber cord is less then $1 foot, you can easily tolerate 100ft cord length to dryer plug from your 240V saw if needed (even 150ft of 12/3 should not drop voltage enough to effect saw). A long saw extension cord may sound expensive @ $1 ft, but its cheaper than electrician or generator. :)

2) Get some more quotes on increasing power to shop. $1800 for one 30A circuit is a rip off (unless the run length is over 400+ feet?). For <$1800, you typically get an entire 60-100A sub-panel installed with bunch of circuits for your workshop (including electrical wiring permits with city/county).
I would ask for quotes on single 20A 240V circuit run to shop, and 60A sub-panel with (1) 20A 240V and (2) 20A 120V outlets; so you can see cost difference. Be sure to ask for cost breakdown. wink wink,

Best Luck.
