46 Overload Test46.1 After being tested as described in this section, each of three receptacles or connectors and their mating devices shall not exhibit any electrical or mechanical failure of the device nor burning, pitting or welding of the contacts that would affect the intended function.Exception: The requirement does not apply to a receptacle or connector mechanically or electrically interlocked where the interlocking means is opened or opens the circuit before the plug or connector is capable of being inserted or withdrawn.46.2 An additional material that is provided with the intent to reduce or confine the arcing in the contact chamber of a plug and receptacle and that decomposes or is otherwise affected by the arcing is to be removed for all of the overload tests.46.3 The device under test is to be operated manually or mechanically in the same manner as the Endurance With Load Test, Section 45, by inserting the plug into the receptacle or the connector into the inlet, while it is connected to a suitable load, and then withdrawing the plug or connector. The equipment grounding contact is to be connected to ground through a fuse. The device is to make and break 150 percent of its rated current for 50 cycles of operation at a rate not higher than 10 cycles per minute.Exception: A device identified as not being for current interruption (interlocked or provided with a control pilot contact) is to be tested as described in 46.2 - 46.9, except that the device is to be tested three times as described in 46.2 - 46.9. For devices rated for both AC and DC operation, a separate specimen is to be tested on each circuit. There shall not be an electrical or mechanical failure that could increase the risk of a fire or electric shock. The device need not function after the completion of the test, and shall not be used for any further tests.
