Commercial kitchen electrical: code-heavy, equipment-specific.
Restaurant and commercial kitchen electrical scope includes dozens of equipment circuits, ventilation hood integration, fire suppression integration, and specific GFCI and code requirements.

Commercial kitchen electrical scope: equipment circuits sized per equipment nameplate (often 20-30 circuits in typical restaurant kitchen), GFCI protection per NEC 210.8(B), ventilation hood electrical (exhaust fan, makeup air, lighting), fire suppression system interface (UL 300 standard wet chemical system shunt trip and audible alarm), receptacle layout per NEC 210.52(C) for counter spaces, dedicated lighting circuits for prep areas. Typical Marin commercial kitchen build-out electrical $15,000-$45,000+ depending on scope.
01Why commercial kitchens are electrically intensive.
Commercial kitchen equipment is power-hungry and varied: electric ranges (40-60A), convection ovens (30-50A), deep fryers (30-50A), char-broilers (gas + electric controls), refrigeration (multiple 20-30A circuits), ice machines (20A), dishwashers (20-40A), exhaust hood motors (15-30A), under-counter receptacles, prep area lighting. A typical restaurant kitchen has 25-40 separate electrical circuits before considering POS, lighting, and HVAC. Each has specific sizing and protection requirements.
Beyond raw electrical load, commercial kitchens have interlocked safety systems. Fire suppression systems (Ansul or similar wet chemical) tied to exhaust hoods must shut off all cooking equipment fuel/power when activated. This requires shunt-trip breakers on cooking equipment circuits, microswitch interface to suppression system, and audible/visual alarm. Building code and health department both regulate these requirements.
02Major scope items.
Equipment circuit map
Each piece of equipment gets dedicated circuit sized per nameplate. Master schedule maintained during build-out. Equipment changes during construction require circuit modifications.
Hood and suppression integration
Exhaust hood motor circuit, makeup air motor circuit, hood lighting, fire suppression system shunt-trip and alarm wiring. Coordinated with hood vendor and suppression installer.
GFCI and code-required protection
NEC 210.8(B) requires GFCI on most commercial kitchen receptacles. Specific exceptions for hardwired equipment. Health department also has receptacle/outlet requirements that overlap and sometimes exceed NEC.
Lighting
Prep area lighting per health department footcandle requirements (typically 50fc at counter surfaces), often with switching for cleaning vs operations. Hood lighting per hood manufacturer specs.
03Marin restaurant project timelines and costs.
Marin restaurant build-outs typically run 8-20 weeks total project including electrical, plumbing, HVAC, finishes, equipment install, health department approval. Electrical scope typically spans 4-8 weeks of that timeline with multiple visits: initial rough-in during framing (1-2 weeks), equipment-specific circuits as equipment is selected (1-2 weeks), final connections and trim work near opening (1-2 weeks), inspection and corrections (1-2 weeks).
Cost varies significantly by kitchen scope. Small QSR (quick-service restaurant) with limited equipment: $12,000-$20,000 electrical. Full-service restaurant with extensive cooking equipment: $20,000-$40,000. High-end restaurant with hood scope, multiple cooking lines, complex refrigeration: $35,000-$70,000+. Equipment lists drive scope; we develop detailed quote from equipment schedule.
Common questions.
Who coordinates between electrical, hood, and suppression?
General contractor or restaurant owner typically coordinates. We work closely with hood installer (often Bay Area hood vendors like Captive-Aire dealers) and suppression installer (Ansul authorized dealers) on integration details. Pre-construction coordination meeting covers responsibility split: hood vendor provides hood schedule and electrical requirements, suppression provides circuit shunt-trip requirements, we wire to specifications and verify integration at commissioning.
Can existing restaurant space electrical be reused?
Sometimes partially. Existing service entrance and main panel often adequate if previous tenant had similar use. Equipment circuits are tenant-specific and usually require modification or replacement for new equipment lineup. Existing hood and suppression typically stay (high replacement cost) and new equipment fits to existing infrastructure. We assess existing infrastructure during planning and identify reuse vs replacement scope.
What about future menu changes affecting equipment?
We design with reasonable expansion capacity — extra capacity in main panel and sub-panels for future equipment additions, spare conduit routes from electrical room to kitchen area, accessible junction boxes for future equipment circuits. Significantly different equipment lineup (gas to electric, or major capacity increases) requires more substantial modifications but expansion-friendly design minimizes future cost.
Marin health department electrical requirements?
Marin Environmental Health follows California Retail Food Code, which has specific lighting (50fc minimum at food prep surfaces), receptacle (specific spacing and GFCI), and equipment requirements. Final inspection includes health department visit verifying electrical compliance with food code beyond standard NEC. We design to both NEC and food code standards; corrections rare when proper design is followed.
How do you handle pricing — flat fee or hourly?
Both, depending on scope. Routine service calls and predictable scope (panel replacement, EV charger install, transfer switch install, fixture replacement) are flat-fee quoted up front. Diagnostic visits and emergency scope are hourly because we don't know what we'll find. Either way, you get a written quote before work starts on anything significant, and we don't proceed beyond the quote without your sign-off.
How quickly can you schedule?
Depends on scope and season. Emergency dispatch: same-day across Marin County (1-3 hours business hours, 1-4 hours after-hours). Same-day standard service: 3-6 hours from call when capacity allows; otherwise next business day. Scheduled service work: 1-3 weeks typical. Larger projects requiring permits and PG&E coordination: 4-12 weeks depending on scope. We're upfront about timeline at the quote stage.
What warranty do you offer on work?
Our standard residential warranty: 2 years on labor, manufacturer warranty on parts (varies by product — typically 1-10 years). Major installs (panels, generators, EV chargers) often have longer manufacturer warranties (5-10 years). If there's an issue with our work in the warranty period, we come back and fix it at no cost. We also stand behind work past warranty — repeat customers and referrals matter more than a transactional fix.
