Engine attempt turn whe tring to start but stops. Wire to battery terminal gets very hot. Are there any safety measures measures that prevent the engine from starting?

Ensure the battery connections are clean and tight. A "loose" connection at the battery can make a battery cable get hot and the voltage drop across a loose connection will make the car hard to start. Low battery voltage/bad battery can cause the cable to get hot as well because low batteyr voltage causes amperage draw to raise.

Sounds like the starter is taking too much voltage to turn the engine, Need to have the starter circuit checked and possibly change the starter or starter relay.
