Clean Room-31

The document provides guidelines for electrical requirements in clean rooms. It specifies that HEPA fan modules should be on separate 20-amp breakers and major equipment isolated. The breaker panel should accommodate all clean room equipment. Light fixtures and outlets must be sealed and of appropriate type. Due to potentially high power needs, the total amperage of all electrical items must be calculated to determine if existing power capacity is sufficient. Fluorescent lights draw 2 amps each, HEPA fans 4 amps each, and outlets depend on the connected equipment but typically 3 amps each. HVAC and other major equipment amperage varies by size and voltage.

• 5 HEPA Fan modules per 20-amp breaker

• All motors, HVAC and major equipment should be on isolated breakers

• Breaker panel shall be surface mounted and sized to accommodate all of the clean

room equipments.

• Light fixtures shall be sealed Clean Room Type, available in (a) Flush lay-in troffer,

(b) drop down lay-in troffer, or (c) Teardrop design.

• Outlets shall be duplex type three wires, grounded, white color 20 amp / 120V. Other

options include isolated circuits and other amperage and voltage receptacles as

required.

• Switches are quiet-type and designed to control the light fixtures as required.

2) Power Requirements

• Due to the potentially high electrical requirements of clean rooms all amperage drawn

by electrical items must be totaled and a determination made as to the capacity and

availability of existing power. Transformers and additional power feeds may be

required.

3) Typical Amperage Criteria

• Fluorescent Light Fixtures 2 Amps each

• HEPA Fan Modules 4 Amps each

• Duplex Outlets 3 amps each (depends on equipment amp draw)

• Air conditioning Chillers, Air Handling units, dehumidifiers, humidifiers, motorized

dampers & other equipment etc. will vary depending on size and voltage.
