Grizzly G1018 jointer circuit size conflict

[Justin DiValentino]

Just picked up a G1018 8" heavy duty jointer off craigslist for $400, not much of a gloat, but jointers are scarce in my area, especially 8"

Anyway...

The jointer came with the original manual which specs a 30A 220v circuit, see below






However, when I go on the Grizzly website and look up the manual for this machine, it specs a 10-amp, 220v breaker/circuit



I am inclined to believe the manual that came the machine. I also looked for a THQP double pole, 10A breaker and it doesnt seem to exist. But 30A vs 10A is a huge difference and could be dangerous if not sized properly. I've already sent a message to grizzly customer service, but I was hoping to get this installed today. Let me know what you guys think.

Thanks.

Check out this manual from Grizzlys website.

I doubt it needs 30A 220V as that is what you used for a 4-5HP motor that you find on the bigger stuff. You probably have a 2-3HP motor which should be on a 20A 220V circuit (they don't make 10A circuits). Check the motor plate, my guess is that you have a 2HP motor that draws 10A at 220V.

First, there is often conflicts with the Grizzly spec sheets/manuals etc over circuit size, some of them are VERY conservative. They also have been know to change to more efficient motors over time. Check the motor plate I would bet it is under 15 amps and thus will run on any 240V circuit.

I thought that seemed high. Its a 1.5hp motor. I did find a GE THQP 2x15Abreaker on amazon.

Hi, this is a common issue with equipment, the machine may be rated for a maximum circuit ampacity, and that must be followed if specified by the manufacturer.

For example my Hammer B3 Winner has a maximum current of 16 amperes and must be used with a circuit not exceeding 20 amperes.

The equipment is designed and certified for this size of circuit protection, using a larger circuit could'

- void your warranty

- damage the machine if an electrical fault occurs

- become a fire hazard if a fault occurs.

Regards, Rod.

Is that the one with a 1-1/2hp motor? Check the motor plate for hp and amperage draw.

When I had a G1018, I ran it on a 240v/20amp circuit.

You can use an HVAC type outside disconnect with 10A fuses between the circuit and the outlet if you feel like you need to go lower than 15A.

I don't think Grizzly rates for max ampacity, only minumum.

Hi Van, in this instance the manual did state maximum ampacity, which makes me think it's made with IEC compliant components..........Rod.
