Do GFCIs go bad?

Same with the circuit breakers in the panel

I had no idea about circuit breakers going bad until I was working with a big router that kept popping my 15amp breaker, I ended up replacing it with a 20amp and then had the guy tell me that every time a breaker pops it takes less amperage to pop it again. It got to the point where that 15amp breaker was popping every ten minutes or so, it was big router...like a 3 horsepower.
 
AMEN!

I dabble in the simple stuff like replacing switches, outlets and timers.
My friend, and neighbor, wanted to have a timer installed. Sure thing I say, have done a few. I open the box and there were 6 or more circuits coming into it. :eek::eek: I closed the box and told him to call an electrician. :D

As an old gunsmith told/taught me
1 Know how to do the job.
2 Know when you can do the job.
3 Know when to NOT do the job. The job is beyond your skill level.

Circuit breakers are there to protect the wire runs.
The wire must be rated for that breaker's value.

When a new Customs GoFast caught fire on a chase,
there were no breakers/disconnect between the batteries and the terminal strip in the electronics overhead box.
12VDC 8AWG wire run shorted due to sharp edges in the holes, thru the aluminum T top legs, and the canvas was on fire.

Low bidders, with no knowledge of anything, got the work.
I got to teach the Agents what to check for after dressing down the incompetent installers.

At Nuke school in the Air Force, the instructor said,
"radiation, no parachute and electricity can kill."

No breakers AND no grommets?:eek::eek::eek:
 
We had one die in the garage. One day it just no longer worked. It was maybe 15 years old. That was about twelve years ago, and none of the others have failed yet. It did probably get the most use of any outlet in the garage.
 
I had one in the panel that would not reset. I did not stick a wedge in to keep it live. :eek: :)

Turned out to be a bad breaker and not a fault in the wiring.

Ladder…… NY Rangers. Really? I liked you until I saw that. They stole my Sabres captain Chris Drury. It's been all down hill since. In fact they are currently unwatchable
 
I have 3 GFCIs installed in the appropriate places. One covers outside circuits and it has tripped several times when I washed the house. Now, I cover the outside receptacles so that no water can possibly enter them. The original covers were not very waterproof.

At any rate, all of the GFCIs are original. The house is 36 years old.
 
Our bedrooms have GFCI breakers. Don't know if that was code 20 years ago when the house was built or the contractor or electrician just thought it was a good idea. The bathrooms, kitchen, garage, and outdoor plugs are GFCI protected by outlets as they should be (no more than 3 outlets in a chain).

Haven't had any fail yet, but the GFCI breakers are pretty sensitive. I had a vacuum cleaner that would trip the breakers in the bedrooms. Had to use an extension cord and plug it in in the hallway. I'm guessing it was pretty close to the limit of the 15A breakers. The newer vac does not have that issue. The outdoor ones sometimes trip during thunderstorms, which is to be expected.

I'll tackle minor electrical work - replacing switches, outlets, lighting fixtures, hard wired appliances, breakers. Anything bigger than that will need a professional. A man's got to know his limitations.
 
We kept flipping a breaker while using a large tool in my garage many years ago. We were overloading, so I cranked my generator and used it.

Our freezer in the garage was on that line, so I discovered days later when in the garage. The inspector helping me reset it every time before, so I didn't think about checking it. The things we learn trying to save a few bucks. The venison in the freezer had to go, along with fish and shrimp. No store-bought meat, but a lot of hard work was gone. At least we got the roof repaired, right?

Might want to check the wire size of the circuit you swapped up to 20A. If it's not #12 or higher, you should consider going back to the 15A breaker.
 
Certainly check the name plate of the motor in question - but this Google chart shows a 3HP can pull 34A at locked rotor at 115V single phase, which I assume is what we are talking. Quite often 15A circuits are run with 14AWG solid. 20A would be run in 12AWG. Your 3HP router will run less amps unloaded, but has the potential to spike well over 15, and even 20A.

Be careful out there…

Breakers labeled SWD and HID can be used as switches with
certain types of lighting.
Have not checked to see about modern LEDs.

Motor startup can spike the amps higher than running under the load's rated demand.
Worn out bearings on an boat's autopilot drive motor, can even make the run amps higher. If the motor ain't fused properly, you might need a fire extinguisher right quick.
A fire in the engine room might set off the Halon system and choke the engines to a full stop.
Not great if you loose engine power while shooting a treacherous inlet. Always advised the owners and gave them options.
Life jackets, jump overboard and if you're a lawyer, don't worry, hungry sharks will give you professional courtesy. :D

Yes they go bad with use and age! My son bought a used townhouse about 8 years ago. It was about 25 years old then. We automatically just replaced every outlet and switch in the house. Found some troubling lack of grounds in a few cases, especially where the porch was converted to a enclosed room under air. We then hired an electrician to replace the panel as it was a Challenger.
