belt grinder question

[bluewater23t]

Looking to potentially buy a used Burr-king 960 for home use.

It is two wheel, 1.5hp 1ph motor, 120v.

Does anyone know if this will work in my garage? I dont have any special electrical outlets. Just dont want to purchase this, if it will draw too much power and blow fuses or trip my breaker.

Thanks!!
Ted

Shouldn't be a problem if your wiring is up to code. Belt grinders don't start under a load.

It needs 15 amps, so your standard circuit will work if nothing else is running on the same circuit.

---REVISED---
The newer Baldor 1.5hp apparently now draws 16 amps @120v, so it will need a 20A circuit.

They are nice. Are you looking at a 960-250 or a 960-400?

FYI - if it needs a stand, burr kings bolt to Baldor cast iron grinder stands. I suspect Baldor supplies fhe stands to Burr King.

Having owned Burr Kings, I suggest looking at 2x72 grinders.

They can be so much more versatile. The 960-272 is cool, but I never had that one, they are $$$.

My buddy owns Ameribrade. Lots of different wheels available etc.

The Burr Kings are great, but I feel you can get more for less (unless you found a screaming deal. )

If it has a 15 amp factory plug in it, then it is a good bet that it draws less than 15amps and should run in any outlet that does not have other stuff on that breaker. There are plenty of home items that are near the limit, like toaster ovens and space heaters. They sell 1.75 hp table saws made to run on 120 volts. I don't know if they come with a 15 or 20 amp plug or no plug.

yeah, its got the 90 degree orientation of the flat blades in the plug. i dont have an outlet for that, so dont think this is going to work.

its a 960-250, on a stand.

If both blades are horizontal, it is a NEMA 6-15 plug, 240V @ 15A

If one blade is horizontal, it is probably a NEMA 5-20, 120V @ 20A

Most 120V, 15A circuits get marginal running a true 1.5 HP motor (not some NF/ Craftsman mythical peak input power 1.5 HP).

yes, one blade is horizontal.

So is that's the case, he just need a dedicated 20 amp circuit,
20 amp breaker, #12 with ground and the dedicated 20 amp outlet, Correct?

so what would that require? easy job to have an electrician come in and do this? big job, little job?

thanks

Keep in mind there are two plugs that use one blade horizontal, and one blade flat. One is the 5-20 120v 20A plug, the other is the 6-20 240v 20A plug. The only difference is which blade is horizontal, and which is vertical.

Usually 1+ HP motors can be configured to run in 120 or 240v operation, so verify which it is.

yah, its definitely the 5-20 120v 20A plug at the end of it.

A 1 1/2 hp motor will draw somewhere around 13 amps +- while running but start up amperage could easily be as much a 20 amps. To get that circuit if your current wiring is not fused at 20 amps you will need new wire as well as breaker. How much wall will need to be exposed to run that wire? Most homes can be wired through the ceiling or basement/crawlspace but ymmv.

thanks- best option likely get a dedicated outlet wired appropriately. Fuse box already in the garage, so should be straightforward.

If you are going that route, and with the fuse box in the garage, why not run a 240 circuit? That motor would be happier running at the higher voltage.

X2, and then you'll be ready when you get a welder or other 220 volt machine down the road.

I am not sure you can reconfigure the voltage on the 960 series. I know the older variable speed versions cannot. Burr king does not show changing voltages in the manual. If you could change voltages, it would be better to run it at 240V. Call burr king and ask.

You can. It's in the listing as well. .... https://www.burrking.com/catalog/p-100004/model-960-250-2.5-x-60-two-wheel-belt-grinder

(I don't think I've ever seen a .75hp?/1hp or larger Baldor that can't be changed on 120 vs 220.)

Here is a pic of the beast in question. Worth the effort to get new wiring installed?

Something to check is whether or not your outlets are wired with 12 gauge or 14 gauge wire. It's not uncommon to have 12 gauge wire ran to 15A outlets with a 15A or even 20A breaker.

If the wire is 12 gauge, and you have a 15A breaker, you can just swap the breaker to a 20A. Most if not all outlets are rated for 20A - even if they're NEMA 5-15.
