3.5 Automatically controlled dishwasher – A dishwasher or a unit of a system for which energization of a motor, a solenoid, a magnet, or similar component occurs without manual intervention. Automatic control also occurs during any single predetermined cycle of operation, when automatic changing of the mechanical load reduces the speed of a motor so that starting-winding connections to the branch circuit are reestablished. 3.6 Auxiliary control– A control intended primarily for the regulation of time, temperature, pressure, or operations under conditions of normal operation, and is not intended to address abnormal conditions such as overload or above maximum normal operating temperatures resulting from abnormal operation. 3.7 Barrier– A partition for the insulation or isolation of electric circuits, for the isolation of electric arcs, or for the isolation of moving parts or hot surfaces. In this respect, a barrier can serve as a portion of an enclosure and as a functional part. 3.8 Continuous-duty motor – A motor that, under any intended condition of use, is intended to operate unattended and under load for 3 hours or more. 3.9 Cord-connected dishwasher– A dishwasher that is connected to the electrical supply by a power-supply cord or cord set. 3.1 0 Factory-wired – The installation of wiring or wiring harnesses on or in the equipment in the factory. 3.1 1 Field-wired – The wiring or wiring harnesses which are connected to the equipment in the field. 3.1 2 Field wiring terminal – A terminal to which a power supply or control connection is made in the field when the dishwasher is installed. 3.1 3 Igniter– A device that utilizes electrical energy to ignite gas at a pilot or main burner. 3.1 4 Internal wiring– Wiring that is interconnecting beyond the point where the power-supply cord of a cord-connected dishwasher enters the enclosure, or beyond the wiring terminals or leads for power-supply connection of a fixed dishwasher.
