AggieBlacksmith Posted June 10, 2018 Posted June 10, 2018 Howdy smiths, So here's the short of it: I have a Fasco B24220 AC blower and I want to wire it to a foot pedal which will plug into a standard outlet. My trouble is, I'm electrically challenged. Any advice on electrical specs/wire/foot pedal I can buy to accomplish this? Here's the info on the wires connected to the blower (which which happens to be a NON POLARIZED AC MOTOR?): CSA CL1251 OR AWM I A/B 1258C 600V Ft-2 E29326 AWM 125*C 600 V Style F 3173 18 AWG Suitable for Switchboard Wire. Thanks and Gig'em! Micah Quote
WayneCoeArtistBlacksmith Posted June 10, 2018 Posted June 10, 2018 1. Wire the fan to a standard 115v power cord. 2. Go the Harbor Freight and buy a foot pedal . The have both on/off (press the pedal once to turn it on, then again to turn it off) and "Dead Man" type (press the pedal to turn it on, remove your foot to turn it off). Plug the power cord into the outlet on the back of the pedal switch then the pedal switch in to the outlet. Let me know if I can help you Wayne Coe Quote
AggieBlacksmith Posted June 10, 2018 Author Posted June 10, 2018 Thank you Wayne, that's exactly what I was looking for! So just to be sure, the blower needs to be wired to a 2 terminal, non-polarized 115v power cord? Quote
Charles R. Stevens Posted June 10, 2018 Posted June 10, 2018 3 wire polarized is safer. If the blower only has 2 leads, the third (great) would connect to a fashioner fastener on the metal case. So In case the motor shorts out internally and energizes the case the breaker will trip. It would suck to touch an electrified case. This is why most appliances are now wired this way . Quote
AggieBlacksmith Posted June 10, 2018 Author Posted June 10, 2018 What exactly do you mean by a fashioner and how would you attach it? Quote
Charles R. Stevens Posted June 10, 2018 Posted June 10, 2018 Fastener, as in a screw or bolt. My spelling stinks and adaptive text makes it worse Quote
AggieBlacksmith Posted June 10, 2018 Author Posted June 10, 2018 No problem. So you literally just run the third wire to a screw on the outer casing? Also, with a 3-terminal, would wires from the top 2 terminals on the each wire to the 2 blower wires and then the wire from the bottom terminal on the plug fasten to the the casing? Quote
Charles R. Stevens Posted June 10, 2018 Posted June 10, 2018 110 ac is color coded, white is neutral, black is hot and green is ground. Green goes to the mental case. Yes it is the center lug. Quote
AggieBlacksmith Posted June 10, 2018 Author Posted June 10, 2018 That's the problem though, the 2 wires on the blower don't distinguish between hot and ground. Quote
Steve Sells Posted June 10, 2018 Posted June 10, 2018 that second wire is not ground its neutral, carries the inbalance of the load when in use Quote
Charles R. Stevens Posted June 10, 2018 Posted June 10, 2018 Look at the wire insulation, is one marked or embossed? It may be desighned for only a two conductor set up were polerity doesn’t mater, but even then a three wire set up with the metal case grounded (not tied in to the neutral) is a safer set up. Infact the motor is clearly marked as requiring a ground Quote
MarkDobson Posted June 10, 2018 Posted June 10, 2018 is there a box on the side of the motor those wires come out of? if so here should be a screw in the box for your ground (its usually green). it shouldnt make a difference which wire is hooked to which since they arnt marked. if it doesnt work or it sucks instead of blows switch the wires Quote
Steve Sells Posted June 10, 2018 Posted June 10, 2018 its AC power, why would it run backwards? and why do people post wild guesses when a man asks for real help? IF it is running backwards you have other problems Quote
Charles R. Stevens Posted June 10, 2018 Posted June 10, 2018 From their website it appears to be non polarized so the white and black from your cord can go to either lead, some kind of encloser to isolate/protect the connections would be ideal (its desighned to be inside an encloser so loose wires aren’t a concern) Quote

Just checking. 2 hours ago, Glenn said: Photos will make things a whole lot clearer. I can see in your photos that there is a conduit box hidden under your hand. That is where all of your work will be done. If you are still in need of direction, post a well-illuminated photo of the inside of that box. Robert Taylor Quote
AggieBlacksmith Posted June 10, 2018 Author Posted June 10, 2018 Hey Robert, I'm probably gonna call Fasco tomorrow and get tech on the phone to see what they recommend. Here's the photo of the inside of the box. There are literally no markings inside and again, both wires are identical in every way. Quote

Please explain how AC motors can run backwards if the 2 wires are switched. Please provide references if possible as I want to look into this if it is indeed an option. Quote
Steve Sells Posted June 10, 2018 Posted June 10, 2018 Done let the unlicensed unknowing guesswork scare you. You have 2 conductors. Connect one of them to the white, and the other to the black, Green (or bare) wire connects to the case. that is as simple as that, plus wire it into the foot pedal Wayne showed you for added control. In order to run backwards as any REAL ELECTRICIAN knows, it requires more than 2 wires for that operational option on a single phase AC motor Quote
AggieBlacksmith Posted June 10, 2018 Author Posted June 10, 2018 So let me get this straight...the best course of action would be: Use a 3 terminal power cord...connect EITHER of the two black blower wires to EITHER of the white/black wires...connect the green wire to a screw on the blower chasis...plug the 3 terminal plug (that those the wires converge into) into the foot pedal...and then plug the foot pedal into an outlet. Sorry, like I said, I'm electrically challenged. Quote
Charles R. Stevens Posted June 10, 2018 Posted June 10, 2018 Yes sir. Best to just attach the green to the metal box. Quote

Dale Russell Posted June 11, 2018 Posted June 11, 2018 My 2 cents ... If in doubt take it to a LICENCED ELECTRICIAN & get them to wire it up . Dale Russell Quote
