2. Leads connected to the terminals shall be insulated for at least 275V and this insulation shall
extend to within 1mm of the metal of the terminal throat.
3. ll terminal screws, used and unused, shall be tightened down.
4. Minimum creepage and clearance distances between the terminals and adjacent conductive parts
(including cable entry devices) must be at least 5mm.
5. Painting and surface finishes, other than those applied by the manufacturer, are not permitted.
