Quick answer: Choose food truck equipment by working backward from your local health and fire code, not from a parts list. Confirm every appliance is NSF-certified, total your power load, then divide by 0.80 to add the headroom generators need for startup surges, size propane to your cook line, and add hood suppression plus a Class K extinguisher if you fry or grill. Confirm exact requirements with your local authority before you buy.
Key Takeaways
- Anything that touches food must carry an NSF mark (NSF/ANSI 2, 4, 7, or 8 depending on equipment type).
- Size your generator at your total load divided by 0.80, not at the raw wattage figure.
- Grease-producing equipment like fryers and griddles triggers hood suppression and Class K extinguisher rules under NFPA 96, even on a truck.
- Fire suppression systems need documented inspection every six months, no exceptions for mobile units.
- Propane tank size should match your daily BTU draw, not just your truck's available space.
- Your city or county health and fire authority has final say, so confirm specs before you finalize a build.

Choosing commercial food truck equipment comes down to three filters: does it meet sanitation certification, does it fit your power and fuel budget, and does it satisfy fire code. Get those three right and the rest of the build — layout, brand, finish — is just preference.
This guide walks through what to gather before you shop, the exact order of decisions to make, and where people usually go wrong. We'll also flag the safety steps that matter most, since a failed fire inspection can shut down a truck faster than any other issue.
"What you need before you start choosing equipment
Gather these before you spec a single appliance. Most of this is paperwork and numbers, not tools.
Time: plan two to four weeks to collect code requirements, get cut sheets, and confirm sizing with your authority having jurisdiction (AHJ). Skill level: no technical skill required at this stage — this is research and planning, though you'll want an electrician or propane technician to confirm final sizing before installation.
Gather these before you shop
- ☐Your local health department's mobile food unit equipment list and sink requirements
- ☐Your local fire code or AHJ contact for hood, suppression, and extinguisher rules
- ☐A full appliance list with running and startup wattage for each item
- ☐Your planned cooking fuel (propane or electric) and daily cook volume
- ☐Cut sheets or spec sheets for each appliance showing NSF/ANSI certification numbers
- ☐A copy of your commissary agreement, since most jurisdictions require one regardless of on-truck capability
How to choose commercial food truck equipment step by step
Follow these steps in order. Each one depends on the information from the step before it, so skipping ahead usually means redoing work later.
Safety warning: before you finalize any cooking equipment, confirm whether it produces grease-laden vapor. Fryers, griddles, and charbroilers trigger hood suppression and Class K extinguisher requirements under NFPA 96, and this applies to trucks the same way it applies to a fixed kitchen.
Step-by-step: choosing your equipment
1
Confirm your local code requirements first
Call your health department and fire authority before you buy anything. Equipment lists, sink counts, and power or propane allowances vary by city and state, so a list that worked for a truck in another state may not pass locally.
2
Build your full appliance list
List every piece of equipment that touches food: cooking units, refrigeration, prep surfaces, sinks, and powered prep tools like mixers or slicers. Note each item's power source (electric or propane) and approximate size.
3
Verify NSF certification for each item
Request a cut sheet for every appliance and check it against the matching standard: NSF/ANSI 2 for general food equipment, 4 for cooking equipment, 7 for refrigeration, and 8 for powered prep equipment. Only certified products can legally carry the NSF mark, and inspectors check for it item by item.
4
Decide propane versus electric cooking
Propane cooking reduces the load on your generator significantly compared to electric cooking equipment. If you go propane, you'll size a tank separately and add regulators and leak-detection shutoff provisions.
5
Total your electrical load
Add up running wattage for every electric appliance, then add startup wattage for the largest motor-driven units — compressors and some mixers can pull three to five times their running wattage for a moment at startup.
6
Size your generator with headroom
Divide your total calculated load by 0.80. A load of 8,500 watts needs 8,500 ÷ 0.80 = 10,625 watts, which means you'd buy an 11 or 12 kW generator, not an 8.5 kW unit. Undersizing here is the single most common and costly mistake in food truck builds.
7
Size your propane tank to your cook volume
Match tank size to daily BTU draw: a 20 lb tank holds about 430,270 BTU, a 30 lb tank about 649,980 BTU, a 40 lb tank about 860,542 BTU, and a 100 lb tank about 2,160,509 BTU. Underestimating this means running out mid-service.
8
Add required fire and life-safety equipment
If you have any grease-producing equipment, install a listed hood suppression system and a Class K extinguisher, and mount visible extinguisher signage at the required location. This applies identically to trucks and brick-and-mortar kitchens under NFPA 96.
9
Schedule your suppression system inspection
Fire suppression systems in mobile cooking operations need documented inspection every six months under NFPA 96. Book this before your first health or fire inspection, since many AHJs ask for the service record on-site.
10
Finalize sinks and prep surfaces
Stainless steel construction and the correct number of sinks (handwash, three-compartment, or both depending on your jurisdiction) are almost universally required. Confirm the exact count with your health department before installation.
Common mistakes when choosing food truck equipment
Most equipment-related inspection failures trace back to a handful of avoidable mistakes.
Watch out for these
Buying residential-grade appliances to save money is the most common mistake. They lack NSF certification and usually fail inspection outright, even if they work fine mechanically. A close second is sizing the generator to running wattage only, ignoring startup surge from compressors and motors. Third is assuming a small truck is exempt from hood suppression or Class K extinguisher rules — size doesn't matter under NFPA 96, only whether the equipment produces grease-laden vapor.
Can I use residential appliances in a food truck?
No. Anything that touches food must be commercial-grade and carry an NSF or equivalent sanitation certification. Residential appliances aren't built or tested to NSF/ANSI 2, 4, 7, or 8, so they won't pass a health inspection even when they perform the job fine in practice.
This applies to refrigeration, cooking equipment, prep surfaces, and powered prep tools alike. If a cut sheet doesn't show an NSF mark, assume it won't clear inspection.
Test your knowledge: choosing food truck equipment
Pick an answer for each question, then reveal it to check.
1. What NSF standard covers commercial refrigeration equipment?
- A. NSF/ANSI 2
- B. NSF/ANSI 4
- C. NSF/ANSI 7
- D. NSF/ANSI 8
Reveal answer
C. NSF/ANSI 7 NSF/ANSI 7 sets minimum requirements for commercial refrigerators and freezers.
2. How should you size a generator for a calculated load of 8,500 watts?
- A. Buy an 8.5 kW generator exactly
- B. Divide 8,500 by 0.80 to get about 10,625 watts
- C. Add 500 watts of buffer only
- D. Size it to the smallest appliance's wattage
Reveal answer
B. Divide 8,500 by 0.80 to get about 10,625 watts The 80% capacity rule means dividing your load by 0.80, so 8,500 watts requires an 11 or 12 kW generator.
3. How often must a food truck fire suppression system be inspected under NFPA 96?
- A. Once a year
- B. Every six months
- C. Only when it's serviced after use
- D. There's no set interval for mobile units
Reveal answer
B. Every six months NFPA 96 requires documented inspection every six months, regardless of whether the kitchen is on wheels.
4. Which piece of equipment would NOT trigger hood suppression and Class K extinguisher requirements?
- A. A deep fryer
- B. A charbroiler
- C. A griddle
- D. A countertop panini press with no oil
Reveal answer
D. A countertop panini press with no oil Hood suppression and Class K rules apply to grease-producing equipment; a dry panini press without oil doesn't produce grease-laden vapor.
Troubleshooting common equipment and power problems
Most food truck equipment problems trace back to power sizing or certification gaps caught too late. Here's how to diagnose the usual culprits.
- Generator trips or shuts down under load: this usually means startup surge wasn't accounted for. Recalculate using the 80% capacity rule and confirm your largest motor's startup draw separately from its running wattage.
- Equipment fails inspection despite working fine: check the cut sheet for an NSF/ANSI mark matching the equipment type. Missing certification is the most common reason working equipment still fails.
- Propane runs out mid-shift: your tank is undersized for your BTU draw. Recalculate using your actual daily cook volume, not just the tank size that fits your available space.
- Fire inspection flags missing documentation: suppression systems need inspection every six months. If you can't produce a current service record, schedule one before your next inspection date.
When to call a professional (and what to buy yourself)
Call a licensed electrician or propane technician to finalize generator sizing and propane line installation. These calculations affect safety and code compliance directly, and a professional can confirm your numbers against the actual equipment nameplate data, not just estimates.
Call a certified fire suppression company to install and service your hood suppression system. This isn't a DIY job, and most AHJs require a licensed installer's documentation anyway.
You can handle sourcing smaller supporting items yourself. A 20 lb propane tank hose adapter connects your tank to your cooking line, and clear fire extinguisher signage helps you meet the visible-marking requirement inspectors check for. A sturdy generator stand keeps your power source secure and off the truck bed, which matters for both safety and space.

Upgrading your food truck refrigeration and prep equipment
Once your power and certification requirements are confirmed, choose refrigeration and prep units built for commercial sanitation standards. Look at Continental Refrigerator units or a True 2-door reach-in refrigerator for cold storage that meets NSF/ANSI 7.
If your menu includes fried items, browse our fryers collection for commercial-grade units sized to your power budget. For hot holding and display, a countertop warmer case keeps food at serving temperature without adding major load to your generator.
Frequently Asked Questions
What size generator do I need for a food truck?
Size it at your total calculated load divided by 0.80, which builds in the headroom startup surges need. A load of 8,500 watts means dividing by 0.80 to get about 10,625 watts, so you'd choose an 11 or 12 kW generator.
Do food trucks need NSF certified equipment?
Yes. Anything that touches food — cooking equipment, refrigeration, prep surfaces, and sinks — must be commercial-grade and carry an NSF or equivalent sanitation mark. Inspectors check cut sheets for the relevant NSF/ANSI number item by item.
Does a food truck need a fire suppression system?
Yes, if it has any grease-producing equipment like fryers, griddles, or charbroilers. NFPA 96 requires a listed suppression system under the hood regardless of whether the kitchen is on wheels, and California specifically requires a UL 300 wet chemical system.
What is NFPA 96 and does it apply to food trucks?
NFPA 96 is the national fire code covering commercial cooking ventilation, suppression, and fire protection. It applies to food trucks and pull-behind trailers the same way it applies to brick-and-mortar kitchens, with no size-based exemption.
Can I use residential appliances in a food truck?
No. Residential appliances lack NSF certification and typically fail health inspection, even when they function correctly. Every appliance touching food needs to meet the matching NSF/ANSI standard for its category.
What propane tank size do I need for a food truck?
Match the tank to your daily BTU draw: a 20 lb tank holds about 430,270 BTU, a 30 lb tank about 649,980 BTU, a 40 lb tank about 860,542 BTU, and a 100 lb tank about 2,160,509 BTU. Calculate your cook line's total BTU need before picking a size.
Get your build right the first time
