# Power and Utility Configuration Before Connecting Potato Processing Equipment

## Key takeaways

- Use summed published kW as a planning inventory, not feeder sizing or guaranteed consumption.
- Match site voltage, frequency and distribution details to the order and delivered nameplates.
- Define pneumatic requirements separately from the optical sorter's listed electrical power.
- Accept the installation through documented checks and representative, measured crop trials.

## Why a Power Total Is Not a Connection Plan

A buyer preparing a potato processing installation often needs one immediate answer: can the available supply support the proposed equipment? Adding the published power values creates a useful inventory, but it does not answer that question completely. The installation also depends on the ordered voltage and frequency, operating combinations, starting behavior, cable routes and existing site loads. Treating the sum as a feeder specification can leave important electrical conditions unresolved before delivery.

We recommend separating the process proposal from the electrical connection design. The proposal identifies which functions are needed and when they operate together; the electrical design establishes how those loads connect to the site. Keep both documents tied to the same equipment revision. Our [guide to defining equipment data before export configuration](https://www.spudmate.com/export-potato-equipment-data-first-configuration/) explains why project conditions should be settled before an order is finalized. Here, the practical objective is a documented handover from equipment selection to locally designed connections.

## Build an Inventory With Explicit Electrical Boundaries

The [BQX-16 / BQX-20 / BQX-24 cleaning machine range](https://www.spudmate.com/products/potato-cleaning-machine-bqx/) has three distinct published power values, so the inventory must identify the selected variant. The [BF4-14 mechanical potato grader](https://www.spudmate.com/products/potato-mechanical-sorting-machine-bf4-14/) provides a separate grading load. The [CASL-2X-1800 intelligent optical sorter](https://www.spudmate.com/products/ai-intelligent-sorting-machine-casl-2x-1800/) introduces both an electrical interface and pneumatic rejection. These are possible process subjects for assessment, not a statement that every project needs all three functions.

For each selected unit, record the published power, ordered configuration and eventual nameplate details separately. Add a boundary column showing what each figure covers and which site services remain outside it. Do not assume the optical sorter’s listed electrical power includes a separate compressed-air installation. Likewise, the cleaning description alone does not establish a site water connection or hydraulic service specification. Record associated services only when the project documentation defines their scope; otherwise, an apparently complete total may conceal additional loads.

| Equipment | Published power | Published electrical specification | Meaning for planning |
| --- | --- | --- | --- |
| BQX-16 / BQX-20 / BQX-24 | 7.5 kW / 11 kW / 15 kW | AC380V/50Hz | Match the power value to the selected variant; voltage and frequency are both stated. |
| BF4-14 | 4.4 kW | AC380V/50Hz | A separate grading load with stated voltage and frequency. |
| CASL-2X-1800 | 30 kW | AC380V, three-phase five-wire system | The wiring-system description is stated; frequency is not stated in this record. |

## Separate Listed Power, Simultaneous Demand and Energy

Power in kW describes a rate; energy in kWh describes an amount accumulated over time. The published product power values are planning inputs, not measurements of consumption during a potato trial. Nameplate details should be checked on the delivered equipment, without assuming that every published figure describes the same electrical boundary. Simultaneous demand is the combined operating load at a particular time. It depends on which equipment is running and how heavily each function is loaded.

As a hypothetical inventory example, selecting the 11 kW cleaning variant alongside the 4.4 kW grader and 30 kW optical sorter gives 45.4 kW of listed equipment power. That arithmetic is neither feeder sizing nor guaranteed consumption. Multiplying it by shift hours does not produce a verified energy forecast. Record actual energy over a defined trial period, then divide by the measured processed mass when an energy-per-tonne comparison is useful. Keep idle time, interruptions and any separately metered utility equipment visible in that comparison.

## Verify Voltage, Frequency and the Site Interface

The cleaning and mechanical grading records specify AC380V/50Hz. The optical sorting record specifies AC380V, three-phase five-wire system, but does not state frequency. This difference matters: one record cannot supply a missing detail for another machine. Establish the destination supply voltage, frequency and distribution arrangement, then match them to the ordered equipment documentation and delivered nameplates. A site described only as having three-phase electricity has not yet provided enough information for connection planning.

Do not treat a 380V specification as universal compatibility with 400V, 415V or 480V supplies. Any location-specific configuration must be agreed for the order and checked on delivery. A qualified local electrical professional must design feeder capacity, cables, protection, earthing, isolation and required interlocks using the actual equipment information and site conditions. Starting-current characteristics and other necessary connection data belong in that review. This guide provides a planning framework, not instructions for rewiring, energized testing or selecting protective devices from kW alone.

2. Match ordered interfaces to site supply
3. Design connections and readiness conditions
4. Trial, measure and record acceptance

Conceptual workflow for power and utility planning, not a machine layout or scale drawing.

## Choose the Process Configuration Before Utility Capacity

Electrical planning follows the required process, not simply the largest available cleaning variant. The listed cleaning capacities span 40 t/h, 60 t/h and >90 t/h, while the grading and optical sorting records list 60 t/h and 40 t/h respectively. These figures do not establish combined-line throughput. If the process routes all material through a lower-capacity stage, a higher upstream rating does not remove that constraint. Define the intended route, feed control and discharge handling before comparing configurations through our [potato processing solutions](https://www.spudmate.com/#solutions).

Pneumatic rejection adds a separate utility question because the optical sorter uses high-pressure air blowing. The equipment specification does not establish air pressure, flow, quality requirements or compressor power. Obtain those requirements for the ordered configuration before selecting the air supply. Rejection activity may vary with the crop and sorting settings, so utility acceptance should include representative material rather than an empty-machine run alone. Keep air generation and distribution inside the project utility assessment, even when their electrical loads sit outside the machine inventory.

## Plan Downstream Readiness Before Upstream Feeding

A useful process sequence establishes the receiving path downstream before admitting potatoes upstream. Discharge destinations need to be available, material paths clear and required utilities ready. This reduces the chance of feeding into a stopped or unavailable stage, but it is process planning rather than a documented control feature. The equipment specifications do not establish an automatic start sequence, PLC logic, utility permissives or coordinated restart behavior. Define the required readiness conditions explicitly with the equipment supplier and installation team.

Starting equipment in a planned order may separate starting events, but it does not prove a particular reduction in peak demand. The electrical professional needs the actual starting characteristics to assess that question. Document normal startup, controlled stopping and recovery after an interruption as distinct operating cases. For each case, identify who authorizes renewed feed and how downstream availability is established. Any automatic interlock or utility-loss response must be specified and verified for the project, rather than inferred from a general recommendation to start downstream first.

## Measure Electrical and Utility Behavior During Acceptance

Begin acceptance only after the responsible electrical professional has completed the installation checks and authorized operation. Agree the trial boundaries beforehand: selected machines, additional utility loads, crop condition, target feed rate and measurement period. Separate empty-running observations from loaded operation, because neither alone describes a full shift. Suitable metering should be arranged by qualified personnel; operators should not improvise access to energized equipment. Record the operating combinations so a measured peak can be associated with a particular process state.

Run representative crop through the agreed route and log processed mass, elapsed time, energy, interruptions and relevant utility observations. Include sorting conditions representative of the intended reject burden when assessing pneumatic supply. Agree acceptance criteria before testing, including sustained operation at the project feed target and verified readiness responses where specified. A short successful run cannot establish seasonal consumption or performance for every crop condition. Retain settings and sample descriptions so subsequent trials can distinguish a utility limitation from changed material or operating conditions.

## Close the Handover With Traceable Operating Limits

The final handover should connect three records: what was ordered, what was installed and what was demonstrated. Preserve nameplate information, the approved electrical design, utility requirements and the acceptance log under the same project identification. Where an issue remains, describe its observed operating condition rather than assigning a cause from the power list. For example, interrupted rejection during a material trial requires investigation of the pneumatic supply and sorting demand; a published kW figure cannot diagnose that behavior.

Use the matrix below to direct follow-up without turning symptoms into unsupported conclusions. Resolve electrical questions through the qualified local professional and equipment-specific documentation; resolve process questions through controlled trials with recorded crop conditions. The result should be an operating envelope with clear boundaries, not a promise that one test covers every future lot. Changes to supply configuration, utility equipment, operating combinations or crop demand should trigger a review of the affected assumptions before the previous acceptance record is reused.

| Observation or decision | Evidence to collect | Next action | Conclusion to avoid |
| --- | --- | --- | --- |
| Site supply differs from the published voltage | Site supply details, ordered configuration and delivered nameplate | Have the supplier and local electrical professional resolve compatibility before connection | Assuming all three-phase voltages are interchangeable |
| Concern about simultaneous starting | Equipment starting characteristics and intended operating sequence | Assess starting events within the electrical design | Sizing the feeder from summed kW alone |
| Rejection becomes inconsistent during a crop trial | Crop condition, sorting settings and specified air-supply observations | Investigate utility delivery and process demand together | Assigning the cause from machine electrical power |
| Energy per tonne appears high | Metering boundary, processed mass, idle time and interruptions | Repeat a comparable trial with the same measurement boundary | Treating a short trial as a seasonal consumption guarantee |
| Restart allows feed before the receiving stage is ready | Agreed restart procedure and evidence of specified readiness responses | Resolve the procedure or specified control behavior before acceptance | Assuming an automatic interlock is included |
