| The right slot. Receptacles are usually identified by their
slot pattern. Two-slot receptacles, found in older houses, are
ungrounded; three-slot models (two slots and the U-shaped ground)
incorporate a grounding slot that connects them to a continuous
grounding system in the household wiring; T-slot receptacles have a
20-amp capacity for use in appliance circuits. |
