Abstract:
Power plugs and cables are used to connect electrical devices to AC power. Plugs or electrical outlets that are incorrectly wired can prevent a machine from working properly. Plugs and electrical outlets with loose connections or faulty contacts can also prevent a machine from working properly. Ungrounded outlets can be a source of danger. Devices connected to ungrounded outlets can cause electric shock. Ungrounded outlets should be clearly marked so all users are aware of the danger.
