1. Disaster Electrical Power An early draft Ray J. Vaughan, MS Last update 6/15/2015

2. Disaster Electrical Power  When to use a generator vs. Temporary  Sizing  Care and Maintenance  Power cables  Power Outlets  Lighting

3. Generator? Temporary?  Think about: Distance Power quality Noise pollution Duration Safety Theft

4. Generator Safety  [Copy info from generator company]

5. Fuel safety  Gas storage container BYOG Hand powered siphon Never suck gas  Refuel while off  Battery Lighting while fueling  No Smoking

6. Oil checks  Log oil changes  Have replacement oil on-hand  Mark max hours/oil change  Clean/replace air filter especially if dusty environment

7. Temporary Power Feed  First a warning: This is not something the average do-it- yourselfer should attempt This is targeted for the electrician in your team The power could come back on at any time You have to assume that every circuit it hot and treat it with total respect

8. Temporary Power Feed  Connecting temporary service to existing power source  Harder to set up  Nothing to refuel  Permission of owner  Check voltages first!  Usually stable, but area recovery repairs could cause outages

9. Examples of temporary power sources  Buildings  Sewage Lift station (if 120/240 VAC)  Traffic Signals  Street lights (check voltage)  Lighted bus stops  Telephone company installations

11. Grounding  Driving a ground rod  Borrowing existing grounds  Bonding Connecting all grounds together

12. Power Required  What are you going to power?  Calculate wattage  Convert to amps

13. Power distribution?  Circuit breaker Panel?  Ground Fault Circuit Interrupter GFCI

14. Cable routing  Keep is safe  Trip hazards  Physical damage Overhead Across pavement

15. Wire size  Wire capacity chart  Voltage drop

16. Connectors  Standardized  15 Amp vs. 20 Amp Diagram  Water proof connectors  Twist Lock

17. Lighting  Types Incandescent Instant on Wattage Waste Florescent Good efficiency Not for cold weather Sodium Odd color Slow to light Metal Halide Slow to light

18. UPS  Good for critical loads  Power while refueling  Generator brownouts

19. Dangers of Back-feeding  Step down transformer also steps up  Fatal voltage can go for miles Kills power company techs

20. Command Post power  Wish list: Breaker panel on a hand truck Emergency light GFCIs Heavy Duty power cables Over head lighting Charging stations Radios Tools

21. Summary  Safety First Use an electrician if at all possible Safety Officer should be briefed before starting or energizing  Do it right the first time  Long term installation
