Electrical supply for construction and temporary sites
Temporary enclosures, generators, electrical phasing and CFO/CFA coordination: EOS Électricité works with works managers and technical directors on construction sites where power conditions both the schedule and site safety.
Site power thought through as a full installation
Works managers know that a site's power supply conditions its schedule as much as its safety.
Construction sites, temporary sites, industrial events: each context imposes its own autonomy, phasing and safety constraints. EOS designs site power with the same rigour as a permanent installation — load balance, selectivity, standardised enclosures, verified earthing, clear labelling.
Constant rigour
Enclosures, protections and earthing treated as a fixed installation.
Controlled phasing
Electrical breakdown aligned with site phases and CFO/CFA packages.
Responsiveness
Ability to deploy quickly in response to a schedule hazard or outage.
What construction management faces
Works managers share four recurring families of constraints.
No grid connection
Site without connection or with insufficient supply during early phases.
Variable loads
Consumption evolving with phases: shell, second fix, finishing, commissioning.
Site safety
Enclosures, IP44, differentials and earthing must remain compliant despite the temporary nature.
CFO/CFA coordination
Power, site lighting and communications must be coordinated with the other packages.
Site phasing continuity and temporary redundancy
For a works director, a site halted for electrical reasons costs more than a weather hazard. Continuity is thought through upstream, with temporary redundancy and controlled switching.
Phasing continuity
Sources sized to cover each phase without disruption.
Downtime reduction
Selectivity and isolation to contain a fault without halting the site.
Generator redundancy
Second source available on critical phases.
Planned continuity
Fuel supply, maintenance and documented follow-up for the full duration of the site.
Temporary supply and backup sources rely on our dedicated offerings: see our continuity offerings.
Construction electrical engineering skills we bring
Our teams work alongside works management, site managers and CFO/CFA coordinators.
Generators
Sizing, sound-insulated selection, fuel supply and supervision.
Temporary enclosures
IP44 enclosures, industrial sockets and standardised mobile distribution.
Earthing
Sized and verified temporary earthing, differential protections suited to the setup.
Electrical phasing
Breakdown aligned with site phases and CFO/CFA packages.
Operational follow-up
Supervision, maintenance and interventions for the whole duration of the operation.
Typical applications on construction and temporary sites
Recurring contexts where our engineers step in.
- New-build construction sites
- Major refurbishments and extensions
- Temporary industrial sites
- Professional and cultural events
- Temporary switchovers during grid works
Engineering and construction regulatory framework
Designed with consideration for the regulatory framework applicable to temporary construction-site power, including principles of IP44 enclosures, differential protection and temporary earthing.
- 01
IP44 enclosures
Standardised enclosures aligned with the principles of weather protection and site use.
- 02
Differential protection
Segmentation aligned with the principles of personal protection in a construction environment.
- 03
Temporary earthing
Earth electrodes sized and verified in line with applicable principles.
- 04
Sound-insulated generators
Equipment choice in line with the principles applicable to noise and urban environment.
- 05
Traceability
Commissioning documentation and operating logbook handed over at the end of the operation.
Our designs are developed in line with the principles of the applicable regulatory framework. EOS Électricité does not substitute for inspection bodies and does not attest to final compliance, which falls under the verification and commissioning procedures applicable to the project.
