When working on and repairing AC appliances and audio equipment, it often happens that the device under test might have a fault that causes excessive current draw and might trip the breakers or even worse, explode on your workbench.
To prevent this, a current limiter is used with an incandescent light bulb that is then wired in series with the device that we are testing and we want to the current limit.
This way, even in the case of a full-on short circuit, the current will be limited by the bulb and there won't be mishaps other than the bulb lighting up.
Check out the video for a full explanation of how it works and how you can build one for yourself.
Step by step instructions can be found on Instructables:

Am your new subscriber frm the Philippines. Much better if the bypass switch is removed to avoid accident in case of negligence. Nevertheless, it's a very nice video for engineers & technicans!

Hey, thanks for subscribing. The switch is there to serve a purpose to test whatever is plugged in under full current once we established that there are no more faults. Some devices will refuse to work properly unless a sufficient current is applied.

Genius. So simple so ingenious. Why did not I think this before... This is the only defect.

Adding a breaker will definitely not hurt any project!

Thanks for the tutorial, really handy. But one noob question: do you have to wire the bulb to the hot wire or it doesn't matter?
@TasteTheCode
@TasteTheCode Месяц назад
As long as it is in series, it doesn't matter. With our plugs, you can turn it around so you never really know which one is which.

May we know what's the wattage of the incandescent bulb?
