A retail fit-out is a race. The lease starts, the rent clock starts, and every day before opening is a day of lost sales. Within a few weeks, an empty shell has to become a lit, air-conditioned, signed and networked store with billing counters, display lighting, CCTV and a fire safety system that the mall landlord will inspect. The electrical work sits in the middle of that schedule, and any delay in it holds up joinery, painting and stocking.
Retail also repeats. A brand that opens one store usually opens fifty, and a landlord who approves one specification expects the same standard everywhere. This guide explains how to specify conduit for stores, showrooms and mall units: what a typical fit-out wires, which grade and size to use, how to plan for frequent changes, how to coordinate with the landlord and consultants, how to run a multi-store rollout with consistent material, and how Trity Pipes supports retail projects. For general commercial wiring, read our guide on conduit pipe for commercial buildings. This post is about the retail-specific job.
What a retail fit-out wires
Even a small store has a surprisingly long list of circuits.
- General and display lighting, including track lights, spotlights, cove lighting and shelf lighting
- Signage and shopfront lighting, often on separate circuits and timers
- Power for billing counters, POS terminals, printers, scanners and networking equipment
- Air conditioning and ventilation, often heavy circuits to split units or ducted systems
- CCTV, access control and alarms
- Network and telephone cabling for POS, Wi-Fi and back-office systems
- Fire detection, alarm and emergency lighting, usually under the landlord's and fire authority's rules
- Back-of-house power for stockrooms, pantry and staff areas
- Kiosks, displays and screens that need dedicated points
Each of these needs a protected route, and a store has limited ceiling and wall space to run them.
Why conduit matters in a store
- Safety in a public space. Customers, staff and children are present, so enclosed wiring matters, and landlords and insurers expect it.
- Neat finish. Visible wiring spoils a retail environment, so cable is hidden in conduit above ceilings and inside partitions.
- Easy change. Stores are re-fitted often, with new layouts, displays and signage, and conduit with spare capacity makes changes quick.
- Fire safety. Flame retardant conduit helps slow the spread of fire along wiring, and malls are strict about this.
- Protection during fit-out. A lot of trades work in a small space, and conduit protects cable from damage by other trades.
Where conduit goes in a store
Above the false ceiling
Most lighting, air conditioning and data runs sit in the ceiling void. Use conduit for lighting circuits, signage feeders and control cables, fixed to the slab or the ceiling structure with saddles at proper spacing. Keep power and data separate, and keep conduit clear of ducts and sprinkler pipework. Plan routes before the ceiling grid goes up, because once it is closed, access is limited.
Inside walls and partitions
Where walls are masonry or drywall, concealed conduit takes power to sockets and switches. In drywall partitions, check the partition system's rules for fixing and fire rating. MMS grade is the usual choice for concealed runs.
Surface conduit where concealment is not possible
Mall units often have concrete slabs and walls that cannot be chased. Surface-mounted conduit in neat runs along walls and columns, or in concealed channels, is common. HMS grade is a better choice where conduit can be knocked by trolleys, stock or displays. Our guide on concealed and surface wiring explains the trade-offs.
Floor boxes and counters
Billing counters and island displays often need floor outlets. Plan conduits in the slab or screed before the flooring goes down, and leave spare ways.
Shopfront and signage
The shopfront faces the outdoors, so conduit for signage and facade lighting must be weather-resistant, with sealed boxes and UV-stabilised compound where it is exposed. Our guide on UV resistant conduit for outdoor wiring explains what to confirm with a manufacturer.
Choosing grade and size
| Area | Typical use | Suggested grade and size |
|---|---|---|
| Ceiling lighting circuits | Concealed or fixed above ceiling | MMS, 20mm to 25mm |
| Sockets and counters | Concealed in walls and floor | MMS, 25mm |
| Air conditioning feeders | Heavier circuits | MMS or HMS, 25mm to 32mm |
| Stockrooms and back-of-house | Surface, exposed to knocks | HMS |
| Signage and shopfront | Exposed outdoor | HMS, UV stabilised |
| Low-voltage data and CCTV | Separate conduits | MMS, 20mm to 25mm |
Use this as a starting point, with your specification and consultant's requirements taking priority. Our conduit pipe size chart shows retail applications in the 25mm to 32mm range, and our LMS, MMS and HMS guide explains the grades.
Plan for change
Retail wiring is rarely final. A store may re-merchandise every season and re-fit every few years.
- Leave spare conduit capacity for added circuits and equipment
- Put pull boxes in accessible positions, not behind fixed joinery
- Use surface or accessible routes where changes are likely
- Label every conduit and keep drawings updated
- Keep draw wires in empty conduits
A slightly larger conduit and a few spare ways cost little during fit-out and save a lot at the next refit.
Working with the mall landlord and consultants
Mall units come with a tenant handbook, and the landlord's approval is part of opening on time.
- Read the tenant criteria early, because they set rules on electrical specifications, fire safety, working hours and material approvals
- Submit the conduit specification and documents for approval before ordering in volume. Our guide on material approval submittals for conduit pipe explains the documents that reviewers expect
- Follow fire safety requirements. Our guide on fire resistant conduit pipe explains how flame retardant performance is judged, and our guide on NBCS 2026 and conduit pipe explains the new fire and life safety framework and why local rules still decide
- Plan night work and deliveries around mall hours, since material often has to arrive after closing
- Keep records of the installation for handover and inspection
Running a multi-store rollout
Chains open many stores to the same design, and the electrical specification should be standardised.
- Write one specification for conduit grade, sizes, fittings and fixing, and use it for every store
- Agree one supplier or a small panel with consistent product, so that stores in different cities use the same material
- Standardise kits. A typical store kit lists conduit by size, fittings, boxes and saddles, so that each site orders the same set
- Plan delivery by city. Our dealer and distributor network reaches 20-plus states, so material can be supplied close to each store
- Keep documents consistent across stores, so approvals and audits are easy
- Review supplier performance after each opening, and share feedback

Mistakes that delay retail fit-outs
- Ordering conduit after the ceiling grid is already up
- Mixing grades and brands between stores
- Forgetting spare capacity for signage and screens
- Running power and data in the same conduit
- Using light grade where trolleys or stock can hit conduit
- Leaving fire stopping and sealing to the end
- Missing landlord submittals, so that material cannot be installed

Frequently Asked Questions
Which conduit grade is best for retail store wiring?
MMS grade suits concealed runs in ceilings and walls, and HMS suits stockrooms, exposed runs and shopfront signage where there is more mechanical or weather risk.
What conduit size should I use for a retail store?
20mm to 25mm for lighting and sockets, 25mm to 32mm for air conditioning feeders and heavier circuits, and 20mm to 25mm for separate data and CCTV conduits. Allow spare capacity for future changes.
Can power and data share one conduit in a store?
It is generally avoided. Use separate conduits for power and low-voltage data, and keep the routes apart.
How do I standardise conduit across many stores?
Write one specification, agree one supplier or a small panel, define a standard kit by store size, and keep documents consistent so landlord approvals and audits are easy.
Does a mall landlord approve conduit material?
Many mall tenant handbooks set electrical and fire safety criteria, and landlords or their consultants review submittals. Check the handbook early and submit the conduit specification and documents before ordering in volume.
Can Trity Pipes supply conduit for a multi-city store rollout?
Yes. Share your specification, store count and city plan, and our team will prepare a standard kit quotation and discuss delivery through our network across 20-plus states.
