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 specificUse NEMA values (ie L5-20)Volts amps phase expected

Step 5 – Determine the BUDGET

For

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 applies525.23 – GFCI only on 15 and 20 amp non-twistlock 125V525.23 – 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.
