Finger Safe Covers
Finger safe covers are installed over the top of the terminal connections to
prevent accidental contact with energized parts. Two covers are required
per pole of each circuit breaker.
Rainproof Covers
Rainproof covers plates are available for vertical mounted 2- and 3-pole
circuit breakers and horizontal mounted 2-pole circuit breakers.
Ring-tongue Terminal Adapters
Ring-tongue terminal adapters are available for ring tongue terminal wiring
of 60 A maximum circuit breakers.
Reversible Lugs
For added wiring convenience, QOUR 10–70 A 1- and 2-pole, and 10–60 A
3-pole QOUR circuit breakers have reversible lugs. Removing the wire
binding screw allows the captive lug body to be rotated and the wire binding
screw reinstalled. This permits the circuit breaker to be flush mounted and
then conveniently wired from the back.
Quick Connectors
In addition to the reversible lugs previously described, 10–70 A 1- and 2-
pole, and 10–60 A 3-pole A QOU circuit breakers have optional field
installable quick connectors.
Quick connectors provide a convenient way to attach two wires using two
standard, 0.25 in. insulated quick connectors per terminal (30 A maximum
per connector). Quick connectors are not furnished with the circuit breakers,
but are commercially available. Connectors suitable for wire sizes up to
AWG #10 can be selected for use with these circuit breakers.
