Each fuse shall be supported in the intended manner in a single pole fuse holder. Each fuse holder shall
be mounted horizontally on a bench or test board of non-conducting material so that each fuse under test
should have its major axis horizontal. If a test board is designed for the testing of two or more fuses in
series, the fuse holders shall be so located that there will be a spacing of not less than 6 inches (152mm)
between any two fuses under test. The fuse holder and any current measuring device connected directly
to the test circuit shall be connected to each other and to the source of supply by means of 8 AWG
(8.4mm
2
) standard, general-use copper wires. Any connection to the source of supply shall not to be less
than 4 feet (1,219mm) long. The test fixture shall be so arranged that each end of the fuse have a 0.5
inches (12.7mm) minimum length of lead in the test circuit.
