First question what happened to blow the breaker they rarely just go bad...and If you do not understand how the panel works it is best to let a professional do it...saying that I will offer my no responsibility advice,,.first open the door panel and at the top you will see the LARGER master shut off switch that shuts all the power coming through the panel...make sure have something like a fan or lamp on where you can see it when turning the power off ONCE THE POWER IS KNOWN TO BE OFF,,,REMOVE THE INNER BREAKER PANEL COVER AND PULL OUT THE BAD ONE AND REPLACE WITH THE SAME AMP ONE replace the inner panel and push the new breaker to ON and turn the master switch to on...you should have power to the lamp or fan etc. JUST MAJE SURE ALL POWER IS OFF ABD BE VERY CAREFUL..

SOURCE: Upsizing breakers

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.

SOURCE: pushmatic breaker keeps tripping everytime I hit

You have it shorted out somewhere along the line. If it is a light switch you are switching, what have you done lately to make this trip? Anything? You might have a bad breaker. You can check it by shutting off the power, pull the wire out of the tripping breaker, put it in another breaker, turn the power back on, switch the breaker on, then hit the switch and see what happens. If it snaps off, it is not the breaker, but the switch, the wires in the box, or the lights, or something along the line, you will have to check each one. New construction has made all lights and all receptacles separate, so if your house is old, you might be looking at receptacles too. Check anything plugged in to an outlet, make sure there is nothing shorting. Hope this helps.

SOURCE: Breaker malfunction- Breaker won't restore power to the circuit

To do this safely you should call an electrician. No way I can give you complete instructions that will be sure to be safe because I can't see exactly what the situation is that you have. But the basic steps include: turning off the main, understanding that you are about to expose the feed lugs TO the main which are still LIVE (and giving them a wide berth!), carefully removing the cover, CONFIRMING that everything else in the box is NOT LIVE (use a non-contact voltage detector - $15 or less), removing the wire from the old breaker, pulling the old breaker out, plugging the new breaker in, connecting the wire to the new breaker (nice and tight), replacing the cover and then turning the main back on.

SOURCE: I have an ITE breaker panel (G2020MB1100) with

Yes they will fit. They are both a single pole breaker. Turn the breakers over. They should look the same and snap into a single slot in the panel the same.

Not sure what you mean by No Clip? A Square D QO Breaker has a metal clip that snaps into the panel on the breaker mount and one on the Bus Bar.

I had a house inspection and in the main panel I have a 20 amp QT breaker that is rated from 15-35. I have a 20 gauge wire and and a 15 gauge wire running to this breaker. Inspector says I need a 15


He is correct. I'll not go into the particulars but the fact is, you have two separate circuits connected to the same breaker. Separate the two circuits by installing another 15-Amp breaker. Although I understand your situation, please understand wire gauge and electrical amperage are two different animals. Breakers are rated in Amperage and electrical conductors are sized by wire gauge. That said, the 20 gauge wire you speak of is actually a 12 gauge conductor and the 15 gauge wire as you say is a 14 gauge conductor. Have a good day.

Blowing breaker


In general house hold circuit breaker of the house is 15 Amps or 20 Amps.

Either you have defected (weak) circuit breaker and wiring or bad Microwave oven.

The 99.99 % house hold Microwave ovens pull less than 15 Amps. They may have internal ceramic 15A fuse or 15 Amp internal circuit breaker.

To isolate your problem:

1. Plug your Microwave oven to different areas (different electrical circuit) if the different circuit breaker still trips... your Microwave oven has a short - Most of them has a small ceramic fuse 15 amps fuse.-also check some inter lock switches at door .

2. If the Microwave oven works Ok then you may have:

2a. You may overload the existing electrical circuit, try to unplug some other appliances

2b. You may have bad electrical outlet receptacle (Replace it with the same type , - may need helps from licensed electrician)

2c. Weak or defect house hold circuit breaker. (Replace it with the same type , brand - may need helps from licensed electrician)

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.

How do I run from a 100 amp main panel to a 60 amp subpanel, 125 from my house to the garage


See 60 Amp sub-panel image

Above image shows drawing of 60Amp sub-panel located next to main panel. Drawing shows #6 wire... 125' distance to garage calls for #4 wire. I ran #4 to my barn and have no problems.

Give thought to how many new breakers you want at garage.
See photo of subpanel that holds three 240V breakers

Using drawing as a guide. Replace existing 240Volt breaker with new 60 Amp breaker. Two hot wires connect to new 60 Amp breaker. Neutral connects to neutral busbar.

More space: You can free up space in main breaker box using a tandem breaker. Or by doubling up 2 lightly used 120V circuits onto one breaker. Do not double-up on 240 Breakers

Conduit: You want PVC conduit large enough to fit three #4 wires. Bigger conduit is easier to pull wires ... and maybe later ethernet wire, or alarm wire etc.

Ground wire: You can put a ground rod at garage and run #6 bare copper between sub-panel neutral-busbar and ground rod. Attach ground wire firmly with grounding clamp.

I want you to check with local electrical supply for exact code in your area concerning conduit requirements, grounding, and wire size. Tighten all lugs very tight against wire.

15 amp breaker will not reset with all load off.


They are sensitive little ****, I know they won't work on a florescent fixture, no lights should be on it anyway, but just in case, and the slightest thing wrong, one wire off, one ground undone, it will snap off. And they do go bad, so don't tear the house down to find the trouble when the breaker might be bad. Hook the wire into an existing 15 amp breaker and see if it snaps that off. Then you will know it is not the breaker but something in the wall. Check it out.

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.

Subpanel


the only way unless the existing wiring is long enough or can be re-routed to the new sub is to use junction boxes with covers and wire nut to connect the wires ( make sure that the wire is the same as the wire you are connecting to and install breakers to accommodate the amperage rating of the wire examples are # 12-20 amp, #14-15 amps , # 10-30 amps # 6 50 amps do not put any 220 volt and 120 volt in the same junction box and no low voltage wire in with 120 or 220 volt wires , if you will need to splice the range wire or any wire larger than #10 i would recommend replacing with new wire if this is not possible then use only connectors approved for the wire to be used .good wiring !
