Delta Radial arm saw 33-990 tripping circuit breaker

Hello

I have had this saw for 8 years with no problem. It is on a dedicated 15 amp breaker. It has just started to trip the house breaker after about 1 minute of running. You do not even need to be cutting anything. Just running the motor for 1 minute or less will trip the breaker in the house. I am not sure if it is the motor or possibly a capacitor. A new motor is $680 dollare while a capacitor is $80. A whole new machine is $780.

I doubt the motor is bad. Try it on another circuit to see if the same problem exists. Due to the inrush current of the motor, the circuit breaker may now be defective after several years of use.

If you have the ability, determine the no load current on the motor, and then try it cutting a piece of wood.to determine the load current. If it is within the rated current of the motor, then it's fine.

More than likely motor but try this , if you have a wrap around amp probe or can borrow one or purchase a cheap one place the amp probe around the positive wire connected to panel breaker ,with meter on proper scale ,start saw and read probe current , if cap bad current will be high and stay until breaker trips , if motor will start high on start ,then low then ,very high and breaker will trip , be careful in panel working around live circuits , the reason it reads this way is because as the motor warms the laminates it the armature separate and cause the increase in current to spike ,if cap bad never gets to speed and has high current draw constantly , to verify cap(1) remove from circuit (2)place a screw driver across terminals to release any charge (3), then take ohm meter on ohms place meter leads on terminals one on each terminal at same time meter will rise and fall back(4) reverse leads and should rise and fall as before if it does this it is more than likely good a lot of electrical reasons for this but this will tell you what you wanted to know , good luck

Have a Sears radial saw model 113-19772c wired for 110 but trips breaker when it starts, is on a 15 amp breaker


check that the 110 is the same as the mains supply to the house
if it is , take it back for a warranty replacement as a 15 amp breaker should be 5 amps more than needed
possible earth leakage ( bad insulation) faulty manufacturer --short
the tripping breaker is an indication of a serious fault in the machine either voltage or manufacture

I have to replace the power switch on my Delta Shopmaster 10" radial arm saw. I have the switch, which is a Delta 438010170206S Rocker Switch has (4) terminals. I need to know which wire goes where????


How many wires do you have? The switch is probably a 2 pole, On-Off. If you have 2 wires, connect them to two terminals on one side of the switch (use an ohm-meter to find which terminals make-break). If there are 4 wires, connect the black and white power cord wires to different sides of the switch. Then connect the two motor wires to the two remaining terminals. DO NOT CONNECT THE BLACK AND WHITE POWER WIRES TO THE MAKE-BREAK TERMINALS OF THE SWITCH. This creates a short in the power cord and will trip a breaker.

We have a 1999 "Thermal


DO NOT install a 20 amp breaker, you can cause a fire. The breaker is rated for the WIRES, and unless you change out the wires, the 15 amp wires will overheat and can cause a fire.
Typically, A/C units need dedicated power, with nothing else on that circuit.
One step that you may try is a new 15 amp breaker. Once a breaker starts tripping, is starts tripping earlier....
You may wind up running a new circuit for the A/C, if you do, size it for the A/C.

My Delta radial saw motor keeps tripping the GFCI circuit. I've tried several separate circuits and they all trip as soon as I turn on the motor (even a 20 amp dedicated circuit). I took off the motor...


saws draw a lot of amps at start up and will normally blow any GFi circuit, if it does the same in a normal outlet,, you might have to disassemble your saw for a good cleaning and lube,,

Have a mcCulloch eletric 300s, it runs slow and trips the breaker.


Hello. If it is tripping the breaker you will have to use a shorter extension cord, or a heavier extension cord. A brief electrical note - most residential circuits are 15 amps. There fore, go to the hardware store and get a 15 amp or even a 20 amp extension cord. This will solve your problem as long as you don't have lots of other appliances drawing on the circuit you are using. A blow dryer for instance, uses a lot of amperage, as does a microwave. Try to use a circuit that is dedicated to your chain saw for the length of time you are using it.

Size of hole in 10inch blade for dewalt power workshop radial arm saw


Most 10" saw blades are bored to fit a 5/8" arbor.
Unless someone has changed the arbor on your saw, I'd say that's 99% sure to work.
Are you making your own blades, or accessorizing? In any event, start with 5/8" and see where that gets you.
If you find this helpful, please take the time to rate my post. Thanks!

High amp start up draw


I don't care what kind of stories Craftsman tells, their numbers don't add up.
One horsepower is ~ = 740 watts of energy.
2.5 hp equates to a steady-state power consumption of  ~1850W and this could be 50% higher during the first second or two after turn-on.  Your 15 Amp circuit is pushed to the limit by that power level; 15 Amps X 120 VAC = 1800W And, motors aren't a breakeven game; part of the power they draw is wasted in heat.

9 amps steady-state would be a power consumption of over 6kw which cannot be right. Either your measurements or the motor is faulty.
