§ 39.283. Cable connectors.
(a) Where used with portable conductors connectors should be used which necessarily disconnect both or all poles from the live source of energy where the circuit is opened.
(b) Connectors shll be so constructed, with guards when necessary, that the person using them does not inadvertently come in contact with live parts, or be burned by arcing when interrupting the largest current for which they are related or marked.
(c) The end of a separable connector which is left alive, or the two ends of a separable connector where both are connected to live circuits, as in battery charging, shall have live parts suitably guarded.
(d) Where connectors are attached to portable cables, suitable means shall be provided for relieving the terminal connections of cable from strains.
(e) Separable connectors should, where practicable, be so designed that the plugs do not fit receptacles rated for larger currents than the plugs.
