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 Large Distribution Medium Distribution 480V or 600V Big-E 208 or 240 V Big-E Transform / Distribute / GFCI Protect Small Distribution Common Distribution Distribute Point to Point Only Cordsets Distribute / Split Phases / GFCI Protection Oscars Gen Cords Big-E Jr Big-E Distribute Multiple Taps Distribute / High Power ( 480 or 600 V ) “Y” “W” 480V Big-E Power Stringers 6000 7000 8000 Series Transform / Distribute / GFCI Protect Distribute with GFCI Protection e-Cart Jr. GFCI 1060/1070 e-Cart eCart Details Transformer Based Converts High voltage to “Tool” voltage 15 kVA for Jr models 30 and 45 kVA are common 480V common in US 600V common in Canada 4 Wheeled frame Combo style enclosure is less $ than traditional panels/pigtails UL listing is near completion NEMA 1 Panel No visible GFCI Indoor Use ONLY Permanent mount new construction NEMA 1 Boxes No receptacle covers Nema 1 Indoor Use ONLY Old Work boxes Public can touch connections Cable strain relief Can’t pull on connection No cord protection Imagine what’s going on on the ground!!
