Temporary power for exhibitions, festivals, roadshows and conferences in Singapore is a compressed version of a fit-out — same standards, much less time, and the venue has to be returned to original condition at the end. The right plan starts before the truck rolls.
The event single-line
For every event, we draw a single-line that names the source (venue supply or generator), the changeover device, the temporary DB, the protective device per final circuit, and the load on each circuit. The single-line is shared with the venue electrician and the event organiser before installation. Changes during build are red-lined on the same drawing, not held in someone's head.
Source: venue supply vs generator
Indoor venues — convention centres, malls, hotels — usually offer dedicated meter-off booth supplies. Outdoor and pop-up events on grass or carparks usually need generator hire, often diesel. Generator sizing follows the load schedule plus a starting-current margin for any motor loads (refrigeration, exhaust fans, lifting equipment). A right-sized generator runs quieter and burns less fuel than an oversized one.
Distribution and protection
- Industrial CEEform connectors for sub-distribution — colour-coded by phase and amperage
- Rubberised, abrasion-rated flexible cabling — never bare PVC on a public floor
- RCBO protection on every final circuit, not optional
- IP-rated junction boxes raised off wet or potentially wet ground
- Cable ramps and matting at crowd-cross zones to prevent trip hazards
On-show monitoring
A standby electrician on site during operating hours is part of the scope, not a bonus. A generator restart, an RCBO reset or a swap-out of a failed sub-DB connector during the show is a routine 5-minute job if a crew is present, and a show-stopping problem if not.
Dismantle plan = next booking
After the show, every cable is reeled in, every junction box logged and removed, every cable ramp lifted, and the venue is photographed back to its pre-event state. A clean dismantle is what gets the contractor invited back.
Temporary power installations are still electrical installations. Cabling and DBs are installed under EMA ELISE Licensed Electrical Worker directory supervision and tested before energisation.
