I am on the verge of buying a 2013 Grizzly G0513ANV band that is currently wired for 110v. I only have a 20Amp 110v circuit in my garage. The spec sheet mentions a 30amp 110v circuit for the newer model.

Does anyone have experience running this saw on a 20Amp 110v circuit? Issues? Concerns?

Anyone have any comments regarding the overall performance of this saw?

Thanks!

Have the G0513 wired for 220V, and never attempted to use 110V wiring.

Have attempted to run other 2Hp motors on 20A circuit. It doesn’t work very well.

A typical 2HP motor requires 18-20A running at full load. Most motor design references show 24A as design rating for a 2HP motor on 110V. and AVERAGE start up inrush current is 125% of rated current, or about 25A. That is why they specify a 30A circuit. Also, not unusual for actual inrush will be over 200% of rated current in the 1st 100 milliseconds.

Sure the motor draws less when not fully loaded, you might get it running and it should work; the issue is start up. You will likely trip breaker with most every start up.
Worse, Breakers are only made to handle less than a hundred trip cycles, after awhile the trip current reduces and they will trip instantly with any near full load.

Some panel mfg make breakers equivalent to ‘slo-blow’ fuses intended for motor circuits. But you still have issue that National Electric code (NEC) section 430 requires 125% of rated current for circuit wiring of a 2HP motor? So even with a 20A MP breaker, would still need 10AWG wire. I highly doubt you have 10AWG wiring inside the walls, that would allow use of motor protection breaker?

Sorry of this is news you didn’t want to read.
But then again, YMMV!

Thanks for the info. It was exactly what I was looking to find out (even if I don’t like the answer). I can probably get a 220v circuit installed.

CaptainKlutz: What are your overall thoughts on the performance of this saw as you have it wired? Any issues or concerns with accuracy, performance, quality, etc?

I got mine used for great price from estate, so it is what it is. it works well, and I like it.

If you look at Grizzly online comparison, the stock G0513 (or G0513ANV) is missing a couple of optional high end features that can be useful depending on how you use the saw?

1) It has stamped brackets holding the cast iron table to base. They work, but can feel slight wiggle if slap a 20 lb log on top of table too hard. Not sure I would trust using stamped versions with angled table setting and large lumber, but have no issue with 90 degree cuts I have made. Grizzly sells the cast iron upgraded brackets as accessories, that come standard on more expensive saws.

2) It has the euro style blade guides .vs. more expensive bearing guides. Have used block, bearing and now euro style guides. IMHO – They all work. The Euro style recommendation is set up with little more gap between blade then bearing style guides. Haven’t seen any issues the couple times I re-saw using 3/4 blade, but some folks think bearing guides are more accurate for heavy resaw work. Again Grizzly sells upgraded bearing guides if you want them. TBH – I haven’t done any veneer re-saw with it where you would see the accuracy issues.

3) It’s missing the foot brake common to many large models. Not a crisis, just need some patience as blade slows to stop when done cutting.

4) Blade length is non-standard. None of PHX local shops carry the right size. Not an issue, just means have to mail order, or visit one of our PHX local custom band saw blade mfg such as:
http://www.echolssaw.com/ or https://www.valleysawservice.com

If you were buying a new one from Grizzly, it’s cheaper to buy upgraded band saw than buy base model and upgrade. But when buying used, you get what you get. You can upgrade the 2 items above for $200 if it matters for your work.

Cheers!

Thanks for the info! I appreciate your time! I am still in the process of trying to build a single garage bay shop and probably need other items before a bandsaw anyway. Seemed like a great deal though on what appears to be a really nice unit so I thought I might jump at it.

Have your say...
