Electrical questions

So I'm new here and new to the beautiful indoors. With a limited background in electrical work I have a few questions. I'm in a older house with a questionable breaker. I'm not worried about tripping the breaker or anything but I'm scared to leave the light on while away at work. I've ran my 600watt along with inline and oscillating fan for 12-16 hours a few times to just make sure nothing crazy will happen. If something were to malfunction would it show in those 12 short hours? I'm pretty much just worried about the light drawing so much power. Any help would be deeply appreciated .

You should be fine leaving them on, especially if you have tested it before. Something wrong would have already happened... I leave lights on all the time, so does everyone else, so it should be all right!...

What makes your breaker "questionable?"

In my opinion, questionable breaker + 600 watts = pending disaster.

Please give more details! A malfunction won't happen with your light, per se, it will happen with that breaker. Depending on what's wrong with it, and the surrounding wiring, it could cause your electricity to go out--best case scenario. Worse case scenario--it could become overloaded and short out, resulting in a fire that could quickly spread, while you're away.

But more details are needed to know...

It's an older "zinsco" breaker. from what I'm aware of lights we're ran by a previous owner.

And my only concern is fire

Does your oven run on the same type of old breaker? I would guess your whole breaker box is the same breakers give or take 1-2 due to replacement. My point is your oven doesn't cause a fire and when baking or broiling the wattage is a lot stronger. A easy bake oven uses 1 100 watt light bulbs. Relax and just pay attention to everything, you will be O.K. Good Luck!

Thanks a million for everyone's input. I'm a little more relaxed now reallzing the oven does probably pull a great deal of more power than my small light and the stove/oven are used on the regular

I had to run an extension cord from another circuit(other side of room in my case) to get all my chit running without popping a breaker(fans on one and lights on another). If you have any worries about over load(fire), that would spread the load across to 2 circuits instead of one.. Your oven is 220(bigger wire) not 110..

If the breakers not popping after everything's warmed I'm guessing it wouldn't end up popping later on correct?

I was thinking more along the lines of cooler wire temps with less load more so than imminent failure.. Heat dissipates electrical energy, so it is more efficient as well in on a very small scale..

Probably going to do that now to avoid any issues thank you

breaker or no breaker . its the wire size you need to be concerned about if the house is built in the 1940 or newer the wire in side the wills in the us should be 14 gage wire . and you can pull 15 amps off one outlet . safely . that 600 light even if its old and a total piece of shit . will not pull more then 10 amps and the fan pulls .5 amps . but I bet the ballast is only pulling like 6 amps is typical . so go to work don't think twice . I also used to worry about the same as you . until I read and understand electrical codes and wires and how to install it . YOUR GOOD !

things to make sure make sure the breaker in the us 110 or 120 volts the breaker can never be more then 15 amps or a fuse over 15 amps . if the breaker is larger then you get fires . I talked to a fire chief . he told me that's the only fires they get from grow houses is when people replace the breaker with LARGER breakers . then what the house was installed with
