"Hot" wiring a dimmer

What is the rule for hot wiring? I know it is not advisable, but if it needs to be done, is it that as long as you do not touch both leads, you are ok?

There is no rule for hot wiring anything. It should not be done. Period.

If you pass an electrical current through your body you risk electrocution.

There is no rule in the _NEC_ about working electrical systems hot.

For rules about working hot, you need to look to work place safety rules, eg. OSHA. These rules basically say that you are not allowed to work a system hot if there is any way that you can avoid doing so, but if you need to work a system hot then you have to go through an entire procedure with calculating out the potential hazard (voltage, arc flash energy, etc.), write up a safety procedure, and then wear proper personal protective equipment (arc proof clothing, insulating gloves, face shield, etc.)

If you are doing this in your own home, then I doubt that there is any rule that would prohibit working a system hot. But it is a dumb thing to do. But there is also no reason to work a system hot. If this circuit is somehow 'life critical', then you shouldn't be messing with it. If you can't get to the breaker panel to shut off the circuit, then you have to fix that problem first!

If you are dumb enough to try to wire a dimmer hot, buy a case. You will fry the dimmer hooking it up hot.
