Convert 110V DC Wiring to 22O AC

[ForceFed70]

According to wikipedia, 60ma AC can cause fibrillation (AKA heart problems) while it takes 200-300mA of DC

DC is more dangerous because its much harder to let go of. Yes, the intensity of the shock is the same and you will get the same burn. But with AC there is a much higher chance you will be able to "let go" vs DC.

This is some funny ****. Google experts.
Scrap it out. The bridge rectifier prob has some large cooling fins that are copper too. Good luck.

I've been shocked by 120vac, and over 400vdc (I work in solar), both ****, and should be avoided at all costs.

I think the most you can hope for is that the conduit is usable, and the electrician would just have to pull new wire. Unless the electrician can still read the labeling on the existing wire, it's an appropriate jacket, it's sized correctly, and there are enough conductors, you wouldn't want him trying to rig it.

Here is an odd bit of trivia (No, I can't explain it either)...

More people are killed with 120 volt AC than with 240 volt AC power. This is based on a comparison where 240 volt (or similar voltages are used) and with the US and other 120 volt countries. It appears that for some reason 240 is in fact safer! One theory is that the higher voltage kicks more people away from the connection than 120 volts does, but so far no one has proved it.

The theory I've heard is that people tend to be not scared of 120vac, so they take shortcuts and do things like work on live circuits. Also, 120vac is by far the most common voltage people encounter (at least in the US) so it stands to reason more people will get 'bit' by it.

Back to DC circuits - one other place where it's used is for light rail and streetcars. In Minneapolis the new light rail system uses 750 volts DC; we also have a streetcar museum that runs the old cars from the early 1900s on a short track, and those cars use 400 volts DC.
