Bottled Water Plant Electrical Load Schedule
Adding every motor kilowatt does not by itself define feeder size, operating demand, starting behavior or the site electrical responsibility.
Direct answer
How should an electrical load schedule be prepared for a bottled water plant?
List every machine, auxiliary and site package with its equipment tag, supply voltage, phase, frequency, connected load, largest motor or drive, starting method, expected operating state and source of data. Group loads by line section and distribution board, then develop demand cases for production, startup, cleaning, maintenance and simultaneous utilities rather than applying an undocumented diversity factor. Record the machine supply boundary, isolator, cable and protection responsibility, earthing, short-circuit information, emergency behavior and backup-power requirement where applicable. A competent electrical designer must size the site system using verified OEM data and local code. Confirm installation through inspection, protective tests, rotation checks and measured operating observations.
System focus 01
Collect verified electrical data at equipment level
Start with the latest supplier electrical schedule and nameplate information, but distinguish preliminary quotation data from approved manufacturing data. Include treatment pumps, heaters, UV or ozone auxiliaries, blow moulders, compressors, dryers, chillers, filler, conveyors, labelers, packers, pallet equipment, ventilation and laboratory or workshop loads that are part of the project boundary. Record separate control supplies and any site-provided panels. The schedule needs an equipment tag and revision source so later changes can be traced.
- Equipment tag, supplier document, revision and connected-load basis
- Voltage, phase, frequency, control supply and permitted tolerance
- Motor, heater, drive, compressor and intermittent auxiliary identification
- Buyer, supplier or third-party distribution and connection responsibility
System focus 02
Model operating demand and starting duty separately
Connected load is a useful inventory, not a prediction of demand. Define operating modes and which loads can run together. A blower compressor, chiller and packer may have different loading patterns, while cleaning can start pumps or heaters that are idle during production. Record starting method, sequence and large transient loads so the designer can review voltage effects and protection coordination. Any diversity or simultaneity assumption should be named, justified and revisited after the final control sequence is known.
- Production, startup, cleaning, standby and maintenance demand cases
- Simultaneous versus mutually exclusive equipment operating states
- Direct, soft-start, variable-speed or other approved starting method
- Documented demand factor with owner, rationale and revision status
System focus 03
Define distribution, isolation and protection boundaries
Show where the plant supply ends and machine electrical equipment begins. Identify incoming switchgear, local isolators, panels, cable routes, protective bonding, control panels and field terminations. The responsible electrical designer must assess fault level, protection, selectivity, cable conditions, earthing and local safety rules using the applicable standards. The machinery supplier should provide the information needed for that assessment. Do not turn a web guide into cable-size or breaker advice because installation method and local requirements materially change the result.
- Point of supply, distribution board, feeder and machine isolator
- Available fault information and equipment short-circuit data
- Protection, bonding, earthing and emergency-disconnection responsibility
- Cable route, environment, termination and inspection ownership
System focus 04
Add power quality, environment and continuity requirements
Electrical reliability depends on more than nominal voltage. Document ambient temperature, humidity, washdown exposure, dust, enclosure location, ventilation and any unstable supply conditions disclosed by the site. Identify sensitive controls, networks, vision systems, coders and laboratory devices separately from large motor loads. Define the required response to supply interruption and restoration, including safe state, recipe retention, data integrity and controlled restart. Backup power should be assigned only to loads supported by a real risk and duration assessment.
- Ambient, enclosure, washdown, condensation and ventilation conditions
- Voltage variation, harmonics or supply events requiring competent review
- Sensitive control, data, inspection and communications equipment
- Power-loss state, retained data, restart sequence and backup boundary
System focus 05
Verify the installed system and preserve the as-installed schedule
Before energization, confirm equipment identity, protective devices, terminations, bonding, labels and inspection status under the approved site procedure. Functional checks should confirm rotation, interlocks, emergency behavior and start sequencing with the mechanical system ready. Record measured demand only under a stated operating condition; a short unloaded reading is not a plant peak. Update the load schedule and single-line documentation for approved field changes and keep them with the line handover pack for future expansion and maintenance planning.
- Pre-energization inspection and required protective test records
- Rotation, phase, interlock, emergency and restart functional checks
- Measured condition, active equipment and observation time basis
- Approved field changes, final schedule and as-installed single line
Electrical schedule
Separate inventory, demand case and verified installation
Give the competent electrical designer traceable inputs instead of a single unqualified total.
| Schedule layer | Input | Engineering question | Evidence |
|---|---|---|---|
| Equipment inventory | Approved voltage, load and starting data | What is connected and where? | Supplier schedule and tagged equipment list |
| Demand cases | Operating states and sequence | Which loads run or start together? | Reviewed demand model |
| Distribution | Supply, fault and installation conditions | How is power protected and isolated? | Approved design and inspection records |
| Handover | Field changes and operating observations | Does the final record match the plant? | As-installed schedule and single line |
Final electrical design, installation and testing must be performed or approved by competent persons under the applicable local requirements.

Buyer questions
Frequently asked questions
Use these answers as a project-planning starting point. Final equipment and performance remain subject to the confirmed brief.
Can the plant transformer be sized by adding machine motor power?
Not responsibly. A competent designer needs verified connected loads, operating demand cases, starting behavior, power factor and harmonics where relevant, environmental conditions, future scope, protection and local utility/code requirements.
What is the difference between connected load and demand load?
Connected load inventories rated electrical loads. Demand represents the loads expected to operate together under a defined case. The relationship depends on the real sequence and must not rely on an unexplained universal factor.
Who supplies the cable from the plant panel to each machine?
The responsibility matrix and contract must say. Record the battery limit, cable and containment owner, termination owner, isolator, test responsibility and the information each side must provide.
Should compressors and chillers be included in the line schedule?
Yes when they support the project, even if supplied by another party. Their starting and loaded demand may materially affect the electrical design and the ability of the line to operate.
