Compliance and Safety Guide
The safety standard for power distribution is UL1640. Make sure you’re compliant and your equipment meets the following standards and avoid these pitfalls:
FOLLOW UL1640 SAFETY STANDARDS
- Class A-rated GFCI protection (trip level between 4-6 mA) on all 15 and 20 amp 125 Volt circuits
- Branch-level circuit protection
- Open neutral and reverse phasing
- 240 volt shut-off circuitry
- NEMA 3R outdoor-rated construction
- Structural integrity with no risk of collapse, fire or conductivity
BEWARE
- GFCI Modules and Circuit Breakers Protecting Multiple Circuits - This invites overload on those components
- GFCI Receptacles - They do not provide the required 240 volts shut off circuitry
- Power Distribution Mounted on Wood - This does not meet the requirements for structural integrity (fireproof, weather protection and collapse proof)
CEP POWER DISTRIBUTION
- Puts power closer to the work area
- Protects tools against under-current burnout
- Allows quick set-up and removal
- Reduces the cost of labor and materials
- Reduces extension cord clutter on the job site
- Helps reduce liability because all equipment downstream of the power source is code compliant, agency listed and safe
- Protects against line-side power deficiencies
- Protects circuits against over-voltage damage
