ERICSON UNIVERSITY LIVE TRAINING SESSION: July 2010 TEMP POWER ADVANCED
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 Temp Power Step 3 – Determine the EXPECTED ELECTRICAL OUTPUT
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 Temp Power Step 5 – Determine the BUDGET

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
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.
