Planning guide
What to know about power
Size to your real load — then add headroom
Temporary power starts with the load: list every tool, trailer, light, heater, and pump that could run at once, with voltage and amperage where you know it. Motors and compressors draw a large surge when they start — often several times their running current — so a generator sized only to the running total will stall when equipment kicks on. A qualified provider or electrician confirms the final size with proper starting-load headroom so the site doesn’t brown out.
GFCI and code on temporary installs
Temporary power on a jobsite is governed by NEC Article 590 and OSHA, which require ground-fault protection (GFCI) on the 120-volt receptacles crews plug into, along with proper grounding and protected cable routing. This isn’t optional paperwork — it’s what prevents shocks and electrocutions on wet, dusty sites. Distribution panels and spider boxes give you code-compliant, protected outlets instead of daisy-chained cords.
Distributing power safely across the site
Getting power from the generator to the work means panels, spider boxes, and properly rated cable — routed so it isn’t a trip hazard, isn’t run through standing water, and isn’t pinched by traffic. Planning cable runs and drop points up front keeps the site safe and saves you from extension-cord sprawl. We map distribution to where the work actually happens.
Lighting, heating, and cooling
Temporary power often pairs with the equipment it feeds: light towers for night work and staging yards, heaters for cold-weather pours, curing, and drying, and spot coolers or fans for hot enclosed spaces. These add to your power load, so we factor them into generator sizing rather than treating them as an afterthought.

Common power and lighting equipment to help you choose. Sizing to your actual loads is confirmed on your quote.
What to include in your request
- List equipment and any known voltage, amperage, or wattage.
- Share runtime, operating schedule, and fuel constraints.
- Identify placement, ventilation, and cable routing.
- Have a qualified provider or electrician confirm final sizing and setup.
Power questions
Will SITE PRO size the generator for me?
We collect the right details — your equipment list, voltages, and runtime — and a qualified provider or electrician confirms the final size, including the surge that motors draw on startup. Sizing electrical equipment is a safety matter, so it’s always confirmed by a qualified pro.
Why is my generator bigger than my total wattage?
Motors, compressors, and pumps pull several times their running current for a moment when they start. A generator sized only to the running total will stall under that surge, so proper sizing builds in starting-load headroom.
Do I need GFCI protection on site?
Yes. NEC Article 590 and OSHA require ground-fault protection on the receptacles crews use, plus proper grounding. Distribution panels and spider boxes provide code-compliant, protected outlets instead of unsafe daisy-chained cords.
How do you get power across a large site?
Through distribution panels, spider boxes, and rated cable routed to avoid trip hazards, standing water, and traffic. We plan drop points around where the work happens so crews have safe power where they need it.
Can you cover lighting, heating, and cooling too?
Yes. Light towers, temporary heaters, and spot coolers are available alongside power. Because they add to your load, we factor them into the generator sizing rather than bolting them on later.
