In short - NO. 15 amp circuits are intended for lighting and outlets and usually have 14 gauge wiring. A 20 amp circuit is usually wired with heavier 12 gauge wire which can carry the increased amps. If you plug in a 20 amp breaker into a 15 amp circuit you run the risk of overheating the smaller gauge wire and starting a fire.

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

Room heater caused 15 amp circuit breaker to go bad. Can we update 15 amp circuit breaker to 20 am (similar to ones next to it)


Probable not, in order for you to install a 20 amp breaker, the wiring must be a #12 gauge cable.Check the power requirement of your room heater. It should be not more than 15 amps. Check and retighten the connections to the heater.
Install a new 15 amps 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.

Keep tripping breakers can i just remove the 15 amp breaker and replace it with a 20 amp ??


I would not go to larger breaker size until I knew why 15 amp breaker is trippingIf you find out that 15 amp breaker is tripping because it is being overloaded or that breaker is getting weak. Then I would replace breaker with the same size because they may have wired some with 14-2 wire instead 12-2, I would not feel comfortable pulling 20 amps, on 14-2 wire. That is my suggestion for what it's worth. Thank you.

My dewalt d27105 saw keeps blowing a fuse, could it be the module


These saws have a rather large amount of draw on a 15 amp breaker... they should be able to operate on a 15 amp breaker, however nothing else can share that breaker.... and if it is an outside plug (GFI) it will be even more likely to trip. If possible, use a 20 amp breaker...they can be found in the garage where central vacuum plugs in. If this isn't an option then ensure nothing else is on a normal 15 amp breaker, use a heavy gauge extension cord, and the shorter the cord the better.

All of dryer functions except it does not heat at all in any setting


There are times that the electrical code is not followed and dryers are wired into two 15 amp breakers rather than one 30 amp breaker. If two 15 amp breakers are used, they can be tied together. All that leads to a possible solution, check to see if you have two 15 amp and if both of them are turned on.

15 AMP versus 20 AMP outlet plug


The circuit is protected by the 15 amp breaker. That's what matters, the wire size and the breaker feeding it. It's OK to have a 20 amp recepticle fed by a 15 amp breaker.

Blown breaker


It sound like all of those go through your bathroom GFCI. I would recommend moving your outdoor circuit breaker indoors if possible or enclosing it to make it water-proof. You may also do some rewiring from your main breaker box ( if you are handy) to eliminate the outdoor box completely considering you have 100 amp / 200 amp breaker box inside your house. If you still have an old FUSE BOX with 60 amp service, I would recommend replacing it with a 100 amp or 200 amp breaker box depending on the size of your house. I would separate the laundry room by itself with 12/2 gauge wire with ground on a 20 amp breaker. You can then take your bathroom (using 12/2 gauge wire with ground keeping your gfci ) and run it to another breaker in the house with a 20 amp breaker or add a new one if there is room in your main box. Now all you have left is the porch light. You can run that separate from everything to your main breaker box using 14/2 gauge with ground to a breaker in your main box by adding a new 15 amp breaker or adding it to another 15 amp breaker that does not have a very high load such as a bedroom. In general Kitchens, Bathrooms, Laundry rooms should be on there own separate 20 amp breakers. Most every other room can be 14/2 with ground on a 15 amp breaker... hope this helps....Joe
