TEMP POWER ADVANCED
Temp Power
How to determine the right Temp Power Product
Step 1 – Determine the NEED
( Distribute or Transform)
Step 2 – Determine the AVAILABLE POWER
- Volts Amps Phase
Step 3 – Determine the
EXPECTED ELECTRICAL OUTPUT
Temp Power
How to determine - con’t
Step 4 – Determine the CONNECTIONS
How will they connect in and out ?
Be specific
Use NEMA values (ie L5-20)
Volts amps phase expected
Step 5 – Determine the BUDGET

Temp Power Selection
NEC Article 520 Theatres…Performance Areas…
520.62 Temp Power Boxes
-No GFCI is required
-Overcurrent protection is required
-Busbars and Terminals must be the right size and type
NEC Article 525 Carnivals…Fairs and Similar Events
525.3 – wherever the requirements of the CODE differ from 525, then 525 applies
525.23 – GFCI only on 15 and 20 amp non-twistlock 125V
525.23 – Egress lighting shall not be GFCI
525.32 – Ground continuity shall be checked each time it is connected
NEC Article 590 Temp Power and Lighting
Think System Approach
•
•
•
•
•
•
Large to medium to small
Generation or commercial power
Need cords to connect everything
Need wiring devices to connect cords
Need GFCI to comply and safety
Need cord protection on site
Quoting Temp Power
•
•
•
•
•
Details, details, details
Avoid shopping list quotes for similar items
Know the basic “bucket $” for temp power
Specific details can change everything
Get all the info before RFQ
• More than 50% of RFQs lack IMPORTANT
details to provide a quick accurate quote.
