| Can a neon sign transformer with an output of 12000V and 30mA kill you? |

One of the worse cases is if a short stub or sharp barb of the wire penetrates the skin. Once a current is subcutaneous, the danger level really climbs. We were given serious training on avoiding sharps attached to even low voltage in a medical products plant... Steve |

Traditionally the only "Limiting" going on is a capacitor in series with the primary winding. I will grab one from storage next time I am in Oceanside and set up a little demonstration. |

Any good pointers for further reading on this? |

Oh. I forgot gapped transformer types. Those would be the most used types lately, apart from switching types that work on a completely different principal. The gapped type works on the principal of reducing the saturation point of the core, but less than the inductance forming a self limiting transformer. Its similar to how inherently limited U.L. transformers are made. Those types can defiantly produce more peak current than rated. I have used them in X ray tube test setups. |
