The company I work for builds products that typically have integrated fuses or circuit breakers. During our product validation testing, we would like to begin integrating a test which will basically be an AC short circuit, in order to get an idea of the effect of the short on our product (for example, how many milliseconds will it take for our circuit breakers or fuses to react to the short circuit). How can I safely create a Line to Neutral short of a live AC circuit?
(The lab that we will be testing in is fully isolated electrically from the rest of the building, and has all of the circuit protection that we will need. The lab is built like a bunker and anyone near the testing will be wearing the appropriate PPE. We know that this testing will be dangerous, and we have all of the safety aspects covered.)
