Temporary power is safe when it’s treated like infrastructure, not a last-minute extension cord project.
This checklist is designed for planners and site ops — not electricians.
0) Pre‑event questions (ask early)
- Who is the qualified person/team responsible for temporary power?
- What is the primary power source (shore power vs. generator), and what is the backup?
- Where will distribution live (and how will it be protected from weather/traffic)?
- Where are wet zones (showers, handwash, kitchens, washdown) that may require extra protection?
1) Use qualified installation for distribution
Large loads and distribution should be handled by qualified personnel. Your job is to ensure the plan exists and is enforced.
2) GFCI and wet conditions
If your site has any wet/wash zones, plan for:
- GFCI protection where required
- routing that avoids puddles and drainage paths
- elevation for connectors when possible
3) Cable routing and covers
- keep cables out of guest flow
- cover crossings properly
- light crossings at night
4) Escalation protocol
Write down:
- who to call for power issues
- when to shut down operations for safety
5) Weather and connector protection
Temporary power fails when connectors sit in water, mud, or heavy foot traffic. Improve reliability by:
- elevating connectors when possible
- keeping connectors out of drainage paths and puddle zones
- protecting distribution from direct rain/spray (without blocking ventilation)
- doing a quick visual inspection after storms or heavy wind
Quick checklist (copy/paste)
- confirm qualified install and a named power owner
- identify wet zones and plan GFCI protection as required
- route and cover crossings; light them at night
- protect connectors from puddles and drainage paths
- publish escalation contact and shutdown criteria
