Topic tags/keywords: question table saw wiring

I just replaced the switch on my Ridgid R4510 (http://www.ridgid.com/Tools/R4510-Table-Saw/en/index.htm) after about 2 years of hobbyist use. Not being electrically-inclined, it looks like some sort of internal fuse was blown (one of the two white wires, not the red or black). I was lucky to find this and replace the part for a whopping $13, and my saw is back up-and-running.

My question – is there something I did to cause this? That I can do to prevent it from happening again? I have a 9ft., 14-gauge extension cord to the saw. It’s rated at 15 amps (same as saw), but I’ve read that the saw can surpass this on start-up. I also live in a pretty old building with probably 1930’s wiring if this matters. I appreciate any and all learnin’ you guys can send me.

Thanks.

I am in the same situation, as my saw is now permanently on. Not very safe, as I have to it and unplug it to start and stop it. I am getting better with handsaws now. I look forward to others input.

fwiw, page 8 of Operator’s Manual indicates your 14 gauge ext cord should be sufficient out to 25 ft

why on earth did YOU fix it? if you’re the original owner, is it under it’s 3 year warranty? and did you register it with the LSA (lifetime service agreement)?

I would suggest that you upsize to a 12 gauge extension cord. Less voltage drop for a given length.

I replaced the toggle switch on my Delta saw with an aftermarket start / stop switch (rockler). It is much safer than feeling around under the table to find the toggle switch and turn the saw off.

The fuse did its job and you were drawing too much current through the switch. This could either be by bogging the motor down (like by feeding the wood too fast) or by the voltage being too low. The low voltage is where the power cord length and guage can come in to play. Make sure that the ends of the cord are free from corrosion. If that checks out of, check the building voltage. You mentioned the building being old. it should be within 10% of the rated voltage of the saw. If its more than 15% too low, call an electrician immediatly.

The low voltage is possible, but the motor being bogged down or even physically stopped with the power on is much more likely.

Thanks everyone for the input. My last cut before it died was some 1/4” plywood (it didnt crap out mid-cut), so I dont think that did it. I have put the motor through its paces with some 8/4 maple and purpleheart in the past though. The only problem with 12 gauge cord is they dont really make it under 25ft. My shop is small so the extra length would be wasteful, or even counterproductive. Good call on the owner’s manual knolltop, I had it out looking for the parts list but never thought about looking up electrical specs. I replaced it myself, toolie, because I thought I could handle it and it would be a learning experience. Probably wasted some money buying the part myself, but I avoided a long downtime and didnt have to haul the saw to a service center. I wouldn’t be surprised, isaac, if it actually was my building. Still some investigating to do. Thanks again everyone, it really helps to have the advice of those who have come before and know more.

Buy 25’ of #2-12 appliance cable with ground, a plug and receptacle for the ends.

I actually bought a 12 ga cord that is about 6 or 8 ft long. It is the flat style though if that matters. They are available.

Have your say...
