6. Temp Power Temporary Power Products are any devices used to control electrical energy for short term durations and are not part of a building’s PERMANENT Electrical system. These devices can include: Electrical Extension Cords, Electrical “Panels”, Electrical Voltage Transformers and a variety of connection electrical devices.

8. Temp Power voltage “the size of the power” 600, 480, 277 240, 208, 120 volts

9. Temp Power voltage “the size of the power” amperage “the force of the power” 600, 480, 277 240, 208, 120 volts 15 to 400 amps

10. Temp Power voltage “the size of the power” amperage “the force of the power” phase “the pipelines of the power” 600, 480, 277 240, 208, 120 volts 15 to 400 amps 1 phase 3 phase

11. Temp Power voltage “the size of the power” Tools, motors, pumps, light bulbs, switches, fuses, circuit breakers are all rated or DESIGNED to operate at a given voltage or range of voltages Household Mostly 120VAC Some 240VAC Automobile 12 VDC AC vs DC Voltage AC or Alternating Current is generator created. DC or Direct Current is created by Battery or AC/DC power supply. Jobsite 600 or 480 VAC 208 or 240 VAC

12. Temp Power Household 100 Watt Light bulb – 1.5 amps Electric Range – 50 amps Jobsite Drill or grinder – 5 to 18 amps Stringlight – 10 to 18 amps amperage “the force of the power” Symbol = A Motors to light bulbs require or PULL a certain amount of amps through the cord. Amps are added on a circuit and called the “load”.

13. Temp Power phase “the pipelines of the power” Symbol = ø The basic count of hot lines in a single circuit. 1 Phase 120V = 1 Hot, 1 neutral & 1 safety ground 1 Phase 240V = 2 Hots, 1 neutral & 1 safety ground 3 Phase 208V = 3 Hots, 1 neutral & 1 safety ground 3 Phase 480V = 3 hots & 1 Neutral/Ground Bonded

14. Temp Power Electric circuits require a hot and return (neutral) side to complete the circuit or loop. Hot + Neutral Return -Source

15. Temp Power Rule: Electric wires (conductors) are sized or rated to carry a maximum amperage or current. Amp chart is NEC 400 – wire sizing #14 awg = 15 amps #12 awg = 20 amps #10 awg = 30 amps # 6 awg = 50 amps Note: Wire “size” goes down as physical wire gets larger and can carry more amps

16. Temp Power Rule: Too much current ( amps ) can burn up circuits – fire hazard. Protection – Circuit Breakers & GFCI Voltage Source Wire size too small

17. Temp Power Rule: Too much current ( amps ) can burn up circuits – fire hazard. Protection – Circuit Breakers & GFCI Circuit Breaker or Fuse PROTECTS the equipment or wiring CLICK Voltage Source

18. Temp Power Rule: Too much current ( amps ) can burn up circuits – fire hazard. Protection – Circuit Breakers & GFCI Circuit Breaker or Fuse PROTECTS the equipment or wiring CLICK Voltage Source CODE RULE: Circuit Breakers or Fuses must be rated for the smallest rated part of the circuit.

19. Temp Power Protection Circuit Breakers protect equipment and wiring. - NOT a life safety device! - Rated in full amps ( 15, 20, 30, 50 etc) - Must be on all branch circuits - Must be rated correctly - Does not do the same job as a GFCI

20. Temp Power Protection GFCIs protect people. -Ground Fault Circuit Interrupter - Quick life saving device - Sensitive to poor connections, cheap cordage, moisture

21. Temp Power Protection Circuit Breakers protect equipment and wiring. - Not a life safety device - Rated in full amps ( 15, 20, 30, 50 etc) GFCIs protect people. - 6 ma trip point ( 6 millionth of an amp) - Quick life saving device - Sensitive to poor connections, cheap cordage, moisture

22. Temp Power Rule: Electrical current will find any path to ground – Including through you! Protection - Circuit Breaker ONLY Voltage Source Circuit Breaker H N Ground Electric current flows to and from tool as normal…

23. Temp Power Rule: Electrical current will find any path to ground – Including through you! Protection - Circuit Breaker ONLY Voltage Source Circuit Breaker H N Ground PROBLEM ! TOOL DEVELOPS AN ELECTRIC FAULT and SENDS ENERGY THROUGH THE WORKER TO GROUND !

24. Temp Power Rule: Electrical current will find any path to ground – Including through you! Protection - add a GFCI GFCIs watch for a mis-match in current on the Hot and Neutral conductors. CLICK Voltage Source CODE RULE: GFCIs are required for all 15, 20 and 30 amps 120V rated circuits on jobsites. GFCI Circuit Breaker H N Ground

25. Temp Power Transform vs Distribution Distribution – “Splitting Phases”

26. Temp Power Transform vs Distribution Distribution – “Splitting Phases”  120 volts ( 1 phase ) – 1 set of 120 V source 1 Hot, 1 Neutral & 1 Safety earth ground

27. Temp Power Transform vs Distribution Distribution – “Splitting Phases”  120 volts ( 1 phase ) – 1 set of 120 V source 1 Hot, 1 Neutral & 1 Safety earth ground  240 volts ( 1 phase ) – 2 sets of 120 V sources 2 Hots, 1 shared Neutral & 1 Ground

28. Temp Power Transform vs Distribution Distribution – “Splitting Phases”  120 volts ( 1 phase ) – 1 set of 120 V source 1 Hot, 1 Neutral & 1 Safety earth ground  240 volts ( 1 phase ) – 2 sets of 120 V sources 2 Hots, 1 shared Neutral & 1 Ground  208 volts ( 3 phase ) – 3 sets of 120 V sources 3 Hots, 1 shared Neutral & 1 Ground

29. Temp Power Transform vs Distribution Transforming Power 480 or 600 volts is available at site. Tools can’t run on “commercial power” levels. The voltage requires transforming to reach 240, 208 or 120 volt ranges.

36. Temp Power Jobsite Problem: How do you run a tool rated at 120 Volts if only 480 Volts are available? Answer: Transform the power to 120V. Transformers either step up or step down voltage based on the design.

37. Temp Power Input 480V 3 Phase 60 Amps Output 120/208V 3 phase (18) 1 phase circuits @ 20 amps each Transform section Distribution section

38. Temp Power Basic Rule: 3 Phase input into a transformer derives 3 phase output. 1 Phase input derives 1 phase output. 480V 3 phase INPUT = 120/208V 3 phase OUTPUT 480V 1 phase INPUT = 240V 1 Phase OUTPUT

39. Temp Power Size Matters: Transformers are rated in KVA – this is the size rating as to the amount of amps they can produce. Every 15 KVA = Max of (6) 20 amp 120 V circuits
