My water heater is electric and in the top where the electric comes in I found water and rust. Is this normal condensation? It is 10 years old but water and electricity do not mix.

Answer

Sounds like your safety valve may be leaking a small amount. You might try letting it cool, turning the water off, and opening that valve a few times by hand, or even just cracking it open while warm and with water pressure. It should let hot water out and shut back off completely.
