Arc flash resistant enclosure with segregated cooling

An enclosure for electrical equipment comprising:

• a low temperature compartment to operate at a first controlled temperature range, the low temperature compartment configured to house a first set of associated electrical components;
• a high temperature compartment to operate at a second controlled temperature range higher than the first controlled temperature range, the high temperature compartment configured to house a second set of associated electrical components;
• a first intake vent to receive ambient air into the low temperature compartment;
• a second intake vent to receive ambient air into the high temperature compartment;
• and
• a blower to direct air from both the low temperature compartment and the high temperature compartment out of the enclosure;
• wherein ambient air entering the low temperature compartment flows along a first cooling path extending from the first intake vent to the blower;
• wherein ambient air entering the high temperature compartment flows along a second cooling path extending from the second intake vent to the blower;
• and
• wherein a terminal portion of the first flow path joins the second flow path prior to the blower.
