Shutdown & off-hours work

Industrial Electrical Rewiring Singapore Factory, Warehouse & Plant

A factory or warehouse rewire happens once every 15 to 25 years, and it has to be right first time: the stakes are production downtime, compliance and worker safety. TRUST ELECTRICIANS plans the rewire around your shutdown schedule and delivers LEW-endorsed, CoC-issued work that stands up to EMA, MOM and SCDF scrutiny.

Is it time?

When an Industrial Rewire Is the Right Answer

Industrial rewires are driven by a small number of triggers. If any of these apply to your facility, a full rewire is on the table.

The facility is 20+ years oldAnd has never had a full rewire. Cables and switchgear may be well past their rated life.
Years of partial upgradesDifferent contractors, no master plan. The installation works, but it is undocumented, non-compliant and risky.
A major incidentFire, flood, lightning or a serious fault has damaged part of the installation and exposed the rest as questionable.
A change of use or capacityNew machinery, higher load or expanded production that the existing installation cannot safely carry.
A regulatory or insurance requirementAn EMA inspection found non-compliances, or your insurer is asking for an upgrade.
A sale or handoverThe buyer or their bank wants a recent CoC and a known-good installation.

Every industrial facility

Industrial Rewiring by Facility Type

Each type of facility has its own scope and constraints. Here is what a rewire typically covers.

Factory
Warehouse & logistics
Production line & machinery

Facility 01

Factory Electrical Rewiring

For manufacturing, production and processing plants: high-load distribution, heavy machinery and the need to keep production loss to a minimum.

Complete cable rewire: every power and lighting cable, sized for the new load
Main switchgear replacement: ACB or MCCB upgrade as required
Sub-DB replacement to match the new circuit count and load profile
Machinery supply rewire: dedicated, isolated and protected circuits
Earthing system upgrade: the most overlooked part, and the one that most affects safety
Power factor correction where SP Services penalises a poor power factor

Factory rewires are usually planned around a major production shutdown. See shutdown planning below.

Facility 02

Warehouse & Logistics Facility Rewiring

For warehouses, distribution centres and logistics facilities: high-bay lighting, distribution boards and dedicated circuits for material handling.

High-bay and low-bay LED lighting, often as part of an LED retrofit (see Lighting)
Dock door and roller door power with proper isolators
Charging stations for electric forklifts and pallet trucks
Conveyor and sortation power, coordinated with the system installer
Industrial sockets: 16A and 32A as needed
Lightning and surge protection for sensitive stock or equipment

Warehouse upgrade? Send your equipment and lighting list.Send Your List

Facility 03

Production Line & Machinery Rewiring

Usually tied to a production reconfiguration, a machine move or a machine upgrade.

Single-machine supply: dedicated circuit from the DB, with isolation and protection
Production line infrastructure: multi-machine supply with coordinated protection, often on its own sub-DB
Machine relocation: disconnect, re-route, reconnect and test before re-commissioning
Soft starters and VFDs for motors that need soft starting or speed control
Control panel wiring for PLC-controlled machinery, with the machine supplier

Main switchgear

Industrial Switchgear (ACB / MCCB)

If your facility has an ACB or MCCB, the rewire is the right time to inspect, test and, if needed, replace the main switchgear. We supply, install, test and maintain:

ACB (Air Circuit Breaker) for main incomers and high-amperage distribution, typically 800A to 6300A. Schneider Masterpact, ABB Emax, Siemens 3WL.
MCCB (Moulded Case Circuit Breaker) for sub-distribution and large feeders, typically 100A to 1600A. Schneider Compact NSX, ABB Tmax XT, Eaton, Terasaki.
Protection relay testing for ACBs with electronic trip units.
Switchgear maintenance: annual or semi-annual inspection, cleaning and tightening.

Safety and uptime

Distribution, Earthing & Protection

A rewire is the natural time to fix the parts of an industrial installation that matter most for safety and uptime.

Sub-DB replacement

New sub-distribution boards matched to your floor layout, circuit count and machinery.

Earthing system upgrade

Often the most overlooked part of an industrial rewire, and the one that most affects safety.

High-load cable sizing

Feeders sized for the real load: 95 mm², 120 mm², 185 mm² and above.

Machinery isolation

Dedicated, isolated and protected circuits for every major machine.

Lightning & surge protection

For facilities with sensitive stock, controls or IT equipment.

Labelling & documentation

Every DB, circuit and isolator labelled, with updated drawings at handover.

Minimise downtime

Shutdown & Off-Hours Works

A rewire that takes 6 weeks of working days is 6 weeks of lost production, which is rarely acceptable. So we plan the work around the shutdown patterns you already have:

Annual maintenance shutdown. Typically 1–2 weeks, often around Chinese New Year or the December holidays. We use it for the most disruptive work: DB swap, main cable replacement and switchgear change-out.
Quarterly maintenance windows. 2–3 days each quarter, used for staged work circuit by circuit.
Weekend and night shifts. For the non-disruptive parts: cable pulling in ceiling voids, surface trunking and equipment labelling.
Phased rewire. For a facility that cannot fully shut down, we rewire section by section and keep the rest live on temporary distribution.

Pricing & timing

Industrial Rewiring Cost in Singapore

Typical ranges by facility size. Every project gets a fixed written quote, itemised by scope, after the site survey. Current rates are on our Electrical Services Price List.

FacilityTypical range (SGD)

Small warehouse$25,000–$80,000

Mid-sized factory$80,000–$250,000

Large facility with ACB switchgear$250,000–$800,000+

Compliance

Industrial Compliance (LEW, CoC, EMA, MOM)

Industrial electrical work in Singapore sits under several regulators. We work to the requirements of all of them, with LEW endorsement on every meaningful job and a CoC for the relevant scope.

EMA

The primary electrical safety regulator. LEW endorsement and a CoC are required for any fixed-wiring modification.

MOM

Workplace safety, including electrical safety in factories, under the Workplace Safety and Health Act.

SCDF

Fire safety, including the fire alarm interface and emergency lighting.

SP Services

The grid operator. We coordinate any planned supply shutdown with SP.

Industrial Rewiring FAQs

Straight answers about timing, shutdowns, staying operational, cost and SP Services.

Ask on WhatsApp Call Us

How long does an industrial rewire take?

It depends on size and scope. A small warehouse is typically 2–4 weeks, a mid-sized factory 4–8 weeks and a large facility with ACB switchgear 8–16 weeks. Power-off time for the main DB swap is usually 4–8 hours; the rest is staged.

Do I need to shut down production for the rewire?

For the main DB swap, usually yes, for 4–8 hours. For the rest, we plan around your existing shutdown schedule (annual shutdown, quarterly windows or staged work) to keep production loss to a minimum.

Can the rewire be done while the facility is operational?

Partially. Surface trunking, cable pulling in ceiling voids and equipment labelling can be done live. Anything that needs a power outage (DB swap, main cable replacement, switchgear change-out) is done during a planned shutdown.

What does an industrial rewire cost in Singapore?

Typical ranges: small warehouse $25,000–$80,000; mid-sized factory $80,000–$250,000; large facility with ACB switchgear $250,000–$800,000+ depending on scope. See our Electrical Services Price List for current rates.

Can you coordinate with my maintenance team?

Yes. Daily progress updates, joint commissioning of new equipment and full handover documentation are standard.
