Breaker started randomly tripping.

Explain to us how a power saw drawing 10 amps works fine when plugged directly into the outlet but trips the breaker when plugged into a 100ft extension cord? I hope your not the resident electrical guru lol
you are using a cheap, light gauge (18-20g) cord, braided wire. use a 10-14g extension and you wont trip anything. use the proper materials and you wont have a problem. it is dangerous to push more current than gauge of wire is rated for.

lol

Wire size dont matter,increase the length to 200ft and use a 10ga cord.breaker stil trips due to wire losses which created more amp draw on the socket which trips breaker
Are one of those guys that cant stand to be wrong?

10g wire will carry 10a just fine on a 20a circuit, breaker won't trip...

and *you, btw...

impedence and drawn current (volts x amps = watts) are not the same thing. if you are dropping current in a hundred feet and the wire is HOT, you are NOT doing something right. any guesses on how to fix the problem?

Pjten does not appear to understand the difference between volt drop and applied current.

I know this thread has been going for awhile I had the exact same problem & first & foremost good extension cords are hard to find if you ran it for awhile without problems &especially if you vegged still no problem now you're running less hours & have evidence of heat at the plug as I did here is what cured my issue I went to the local hardware store & bought a good quality plug end for both the male & female ends (no china crap) cut about 3" back from each end this solved my problem & it don't hurt when the lights are on to check your plug connection at each end make sure they're snug a weak connection generates heat so while you check for a snug connection feel for heat as well

me either =)

the best solution would be to have a new line and box/sockets added in the location you need.
indeed, however, larger gauge will also do as a shady engineering fix.

true story. hope he's glad we don't want him to burn... lol

and other safe options...

LouisB had the circuit overloaded just with the lights.

And that panel is part of what put Federal Pacific out of business. You could weld with some of the old Stab-Lok breakers.
lmao, forgot about that...

I broke the lights up to two different circuits. Everything's fine now. Got new wires as well they don't even get warm now
fantastic! if you want to share details and pics, i will inspect for potential issues...

this is a viable option as long as WIRE IS RATED FOR CURRENT APPLIED...

new ends won't make 20g wire run 20 amps at 120vac or 240vac... it cannot handle the load. like trying to run the hudson through a garden hose...

the cord does not pull amps. when it comes to electrical, don't comment unless you KNOW EXACTLY what you're talking about. your cord statement is relatively benign, but some wayward info is extremely dangerous as electricity can KILL YOU, and bad wiring can cause fires which can KILL YOU!!!

always best to find a professional if you are at all unsure
The cord can be a problem. Not saying it adds amps to the load.

I have a roll around air compressor. When I use too thin a cord it trips the breaker. Use the proper cord and it doesn't.

I'm 3 months into a grow and everything's going good except the past few days my two 600 watt lights have been tripping and shutting off. I have them plugged into one timer (good for 1800 watts) and the timers plugged into a 25 foot extension cord that runs to a different part of the building. I pictured the cord. And I examined it very closely for damage it seems fine. The part that plugs into the wall is starting to yellow tho from heating up I presume? Can anyone give me insight as to why this might be happening. Is the cord just starting to fail from having 1200 watts run through it 12 hours a day? Should I replace the cord? Or maybe try to split the 600 watts up and power the other 600 off a different socket. I'm in Canada so the walls sockets are 120v pretty sure.
If its been fine for months and nothing else is on the breaker then I would replace the cord with a heavier one and replace the breaker.

Breakers can go bad.

case in point.

i had a ten paragraph reply disappear upon posting, and am not retyping. if you want to die, listen to @Pjten . if not, know your shit or hire a professional.

I got a degree in electronics and worked industrial maint on 440 triple phase. That shit will kill you quick.

I've seen many breakers go bad.

I wouldn't know for sure in this instance. I would have to see it to be sure.

I would agree with if one doesn't k ow what they are doing to hire a professional.
