standard defines an “ignition source” as:
“A source of energy sufficient to ignite a flammable mixture and includes,
but is not limited to naked flames, exposed incandescent material, electrical
welding arcs, and any electrical or mechanical equipment not suitable for use in
hazardous locations”.
The Black Jack is defined as “electrical equipment” however the standard does
not define or provide a criterion for the term “not suitable”. However, we confirm:
A. The Black Jack contains two Single Pole 12VDC rocker switches: an LED
Light ON-OFF switch and an UP–DOWN momentary switch. Both switches
are enclosed and carry an Ingress Protection (IP) rating of 64, meaning
they are completely dust tight and water tight from splashing water.
B.
The Circuit protection used in the Black Jack is defined as a 12VDC Short
Stop Automatic Resettable Circuit Breaker. Ignition Protected, IP66,
meaning they are completely dust tight and protected against powerful jets
of water. Maximum current rating of 30amps @12DVC.
C. The 12VDC motor in the Black Jack is brushless and fully encapsulated
with maximum 28-amp current draw @ 12VDC.
D. All hard-wired terminal connections are located within the plastic cover
head housing.
Based on A. to D. above, the 12 volt DC components in the Black Jack, whilst
being deemed “electrical equipment” are not considered an ignition source in
keeping with the Australian Standard’s broad definition that includes “naked
flames, welding arcs etc., that are sufficient to ignite a flammable mixture”.
