Replacing a 50 amp breaker box with a 100 amp breaker box and running new service wire to the meter. Moving the breaker box from closet to room wall for easier and safer access. Do not attempt to do anything you see in the video. This is for entertainment (edutainment) purposes only.
When you buy things from China they might come with a power cable that has 0.5mm2 conductors but is somehow still rated at 10A. we didn’t believe that so gave it a test.
The cable only 0.5mm2 but the rating molded onto the connectors is 250V 10A.
The conductors don’t appear to be copper. They have a high resistance.
The on load voltage at the supply end of the cable was 229.6V
8.7A at the stat and 8.39A just before it shorted out.
Surprisingly, the cable blew itself clear and did not cause the supply circuit breaker to trip.
