Re: Hot Lines
Yes it can.
When it is ringing it has 90 volts on it. So don't be using your teeth to strip the wire LOL
It should be it can cause a shock but the current is so small it wouldn't be a hazard.

Re: Hot Lines
I once had occasion to brush up against a bare 50VDC telephone line. I was sweating pretty bad, and it hit me like a mild 120V shock. I started looking around for the phase conductor I was sure I'd touched.
It may not be life threatening, but it can definitely be unpleasant.

Re: Hot Lines
Not sure about corroding a boat but If it might be electrolysis than thats a common boaters subject. Just bought my first boat.
Do a search on the web and you'll find many sites. here are a few.
watch out the hair removal stuff.

This paragraph below from the first site (4th para.) sounds like a real hazard... There must be a better solution?
The most common source of this external current is the shore power connection, especially the ground lead. Docks are notorious for bad wiring and often the ground lead is not connected to ground, is connected to the neutral, is being used for carrying current to a mis-wired boat, and all other sorts of problems. So the ground lead should never be directly connected to the ground bonding system we talked about earlier. The purpose of the shore power ground lead is to provide a return path for current if there is a short circuit or power leakage from an appliance or the wiring on the boat. You don't want it to connect all the underwater items on your boat to the underwater items on all the other boats and the dock because now your zinc is trying to protect everyone else too.
