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.
