Ungrounded equipment or outlets.
Improperly wired equipment or outlets.
Reverse polarity - equipment or outlets.
Bad or corroded connections - especially ground cables.
Frayed or damaged wiring.
By-passed or inoperative safety devices on equipment.

most of the answers so far are true. However, be aware of electrolysis in your wires. For example if you tie in new copper wire to some old school aluminum wires, you will get a slow but definite chemical reaction between the two. This in turns corrodes the wires just enough that they will eventually not touch and arc. If its bad enough it could start a fire.
