with the circuit conductors and connected to
the equipment-grounding terminal or lead on
the dryer.
• The dryer has its own terminal block that
must be connected to a separate branch, 60
Hertz, single phase, AC (alternating current)
circuit fused at 30 amperes (the circuit must
be fused on both sides of the line).
