A minimum clearance in front of electrical panels of 36 inches is required.
What is NEC Article 110?
This international code sets the rules for energy conservation in buildings.
What is IECC?
Thermostats should be mounted at this height above the floor for ADA compliance.
What is 48 inches?
BAS must always defer to this system during an emergency.
What is the fire alarm system?
This standard defines minimum outdoor air ventilation rates for buildings.
