General Information:
• HLQ carrier comes with 6∑of #18 red insulated solid copper
wire attached to the line side.
• Customer inserts a #18 insulated solid copper wire into load
side receptacle.
• Size of type GMQ fuses varies with ampere ratings.
• Mounts in type HLQ size rejection (size limiting) carrier
(prevents overfusing).
• Fuse and knob are an integral one-piece unit. There are no
replacement knobs (caps).
• Units can be panel mounted with a separate steel clip. For the
knockout hole (see above), choose #BK/A-104. For the key-
hole punch type hole, choose #6374 for panels .043” to .062”
thick, or #4909 for panels .030” to .042” thick.
