A usable kitchen equipment schedule must say more than '13 amp' or 'three phase': it should identify the exact model, supply arrangement, rated load, connection method, isolation, protection and control interfaces.
Installation boundary: This article explains design and coordination principles. Drainage, ventilation, fire, electrical and fabrication work must be designed and carried out by competent people using current project documents, manufacturer instructions and the requirements that apply in the relevant UK nation.
The short answer
For every item, record manufacturer, model, quantity, voltage, frequency, phase arrangement, total rated input, full-load current where stated, neutral requirement, connection type, plug or terminal details, local isolation, protective-device requirements, cable entry position and any control interlock. Mark whether the data is tender-stage allowance or confirmed order information. The electrician must design the circuit from current manufacturer data and site conditions, not a generic kitchen-plan symbol.
Separate design allowance from final connection data
Consultant schedules are often prepared before the final equipment model is chosen. A 20 kW allowance can reserve capacity, but it does not tell the installer whether the ordered appliance is 400 V three-phase with neutral, 230 V single-phase, supplied with a cord, or intended for fixed wiring. Keep a revision column and require supplier submittals before circuit installation. If the model changes, reissue the schedule and mark affected drawings.
Use the type plate and installation manual, not the sales brochure alone. Options can change connected load: steam generators, heated rinse tanks, booster heaters, integral condensers and stacked units all affect supplies. Imported equipment may be offered in several voltage versions. Confirm the exact UK configuration ordered and whether the manufacturer permits field conversion.
The schedule must coordinate controls as well as power
Record extract interlock, volt-free contacts, emergency-stop logic, gas-interlock status, remote monitoring, data connection, dosing pumps and external condensers. A low-power control cable missed from the builders' package can prevent a high-value machine commissioning. Show which contractor supplies and terminates each end.
The electrical schedule should align with the services matrix in the site survey. It also needs installation status: existing supply verified, new circuit required, board capacity pending, cable route agreed and isolator position approved.
What common failures reveal
| Site symptom | Likely installation issue | Practical consequence |
|---|---|---|
| Appliance arrives with unexpected neutral | Schedule records only '3 phase' | Cannot energise or unsafe improvised alteration |
| Circuit too small for ordered option | Tender allowance not replaced with final submittal | Delayed commissioning |
| Cable enters on wrong side | Connection position omitted from elevation | Exposed cable across hot or cleanable area |
| Machine powers but will not run | Control interlock or external enable omitted | Trades blame equipment fault |
| Two schedules disagree | Kitchen supplier and electrical designer control separate data | Wrong circuits installed |
Installation and coordination checklist
- Assign a unique equipment reference matching plans and elevations.
- Record exact manufacturer, model and option configuration.
- List voltage, frequency, phases, neutral, rated input and current data.
- State fixed, plug/socket or manufacturer-supplied connection arrangement.
- Define local isolation, protective requirements and cable entry position.
- List control, interlock, data and external accessory connections.
- Name the supplier and installer responsible for each interface.
- Replace provisional allowances with approved submittal data before installation.
Commissioning and handover
The final schedule should match the labels on distribution boards, isolators and appliances. Attach manufacturer data sheets, circuit references, test certification and commissioning results. Record any setting or link used to configure the appliance for the available supply. Future replacement decisions become safer when the schedule distinguishes available circuit capacity from the load of the outgoing appliance.
Questions to ask before approving the work
- Is this data for the exact ordered model and options?
- Does the appliance need a neutral or external control supply?
- Where is the cable entry in elevation?
- Which interlocks must be proved before operation?
- Who owns revisions when the equipment changes?
Capture the installation detail before it becomes a site problem
Capture the service positions, levels, route constraints and access risks before equipment or fabrication is ordered.
