I have the Sears Contractor Saw 152.221240 or common name on forums is “Zip Code Table Saw”,

It is set up for 110 volts AC.

The Manufacture’s specifications says its a 1.75 hp continuous, @ 15 amps ac.

I am currently using a thin kerf blade, general purpose and it appears to work o.k. but somewhat underpowered?

I checked the AC voltage under no-load and it is only drawing 2.43 amps ac and the voltage is 119 volts ac or about 290 watts total draw, when I cut a piece of say 1”x2” cross cut, the a.c. current draw hardly moves maybe another 100-200 mills or 2.5-2.6 amps total. I can cut 3/4” material without any stall, and provides a clean cut, no unusual noises,vibrations, smoke. Appears to be working but weak in power. I do not have a way of measuring the RPM of the saw, the specifications indicate it is 3450 rpm.

Thus, I wonder if anyone on these forums may have any idea what the normal no-load and under load amp draw of a Table saw of this type of similar type.

I have an a older RAS which I can plug into the same power source, and it is a 2.5hp peak (however they rate this), it draws about 9 amps/119 volts ac, and spins up and works just fine.

Thus I somewhat suspect something it not just quite up to specifications on the Motor itself on the Zip code saw. Starts fine, run fine but just not the power draw I was expecting when measured.

Wiring is 12 gauge and only 6 foot from the ac outlet, with a 20 amp breaker, does not trip. All contacts are clean and secure. As mentioned, starts fine, runs smooth, but not drawing the ac amps that I think that it should.

Any suggestions?

Thanks BobFlyer

I submit the power draw or lack thereof is irrelevant. If the saw is working, and doing the tasks you ask of it, and not overheating itself or the wiring, or tripping the breaker… it’s time to make some sawdust.
