ERICSON UNIVERSITY LIVE TRAINING SESSION: July 2010 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

Web Based Tools For Temp Power Selection

NEC Article 520 Theatres…Performance Areas… 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 – wherever the requirements of the CODE differ from 525, then 525 applies – GFCI only on 15 and 20 amp non-twistlock 125V – Egress lighting shall not be GFCI – 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.
