A portable cabin is only as useful as what is inside it. Two cabins of the same size can feel completely different to work in, depending on the wiring, the floor and whether the air conditioning is planned properly. Many buyers focus on the outer structure and price, then discover later that the electrical load is too low for an AC, the floor is slippery, or there is no space to fit an outdoor unit.
This guide explains the electrical, flooring and AC fittings you should include in a portable cabin before you place the order. It will help you compare quotes properly and avoid costly changes after delivery. If you are looking for portable office cabins or are comparing portable cabin manufacturers in Pune, use this as your checklist.
Quick checklist: what to include in a portable cabin
| Area | What to include |
|---|---|
| Electrical | Distribution board, MCBs, RCCB/ELCB, copper FRLS wiring, conduit, switches, sockets, LED lights, exhaust fan, earthing |
| Flooring | Cement fibre board or plywood base with vinyl/PVC, laminate, tile or anti-skid finish |
| AC fittings | Dedicated AC power point, wall cut-out or bracket support, drain provision, insulated roof and walls |
| Extras | Data and network points, emergency light, fire extinguisher space, window shading |
1. Electrical fittings in a portable cabin
Electrical work is the most important part of the fit-out because it affects safety. Poor wiring in a metal cabin can be dangerous, so never compromise here.
Distribution board with MCB and RCCB/ELCB
Every cabin should have a distribution board (DB) with MCBs for each circuit, such as lights, sockets and AC. An RCCB or ELCB adds protection against earth leakage and shock, which matters in steel and FRP structures.
Copper FRLS wiring in conduit
Use ISI-marked copper wires of the right gauge. FRLS (flame retardant, low smoke) wires are the safer choice. The wires should run inside PVC or GI conduit, or inside the wall panel channels, instead of being left exposed.
Switches, sockets and lights
Plan switch and socket positions before manufacturing. For an office cabin, think about desks, computers, printers, chargers and a water dispenser. LED panel or tube lights save power and give better lighting for work.
Exhaust fan and ventilation
Cabins without proper ventilation trap heat and moisture. An exhaust fan or ceiling fan is useful even in air conditioned cabins as a backup during power cuts.
Earthing
The cabin body must be properly earthed. This is a basic safety requirement that is often overlooked in low-cost cabins.
Match the load to your power supply
Add up the load of the AC, lights, computers and other equipment, and make sure your site supply can handle it. At remote construction sites, check whether a generator will be used.
2. Flooring options for portable cabins
The base structure of most portable cabins is a steel frame. The flooring on top decides comfort, cleaning effort and durability.
| Flooring type | Best for | Points to note |
|---|---|---|
| Vinyl / PVC flooring | Office cabins, site offices | Light, easy to clean, cost-effective, widely used |
| Laminate (wooden finish) | Premium offices, resort cabins | Good look, avoid in areas with water |
| Vitrified or ceramic tiles | Cabins placed at one location for a long time | Heavier, can crack during transport |
| Anti-skid / chequered sheet | Security cabins, industrial use, toilets | Strong and slip-resistant |
| Rubber or FRP flooring | Wet areas and portable toilets | Water resistant and easy to wash |
Check the base under the floor
Ask what is below the finish. A cement fibre board or good quality plywood base over the steel frame gives a stronger and quieter floor than thin sheets alone. Also ask about floor insulation if the cabin will be used in a hot area.
3. AC fittings: plan it before you order
Adding an air conditioner later is possible, but it is easier and neater when it is planned at the manufacturing stage.
What AC provision should include
- Dedicated power point and MCB for the AC, separate from the lights and sockets.
- Wall cut-out or window frame for a window AC, or bracket support and piping hole for a split AC.
- Drain provision so condensate water does not leak inside the cabin or wall.
- Reinforced mounting point for the outdoor unit so the panel is not damaged.
Insulation makes the AC work better
A bare metal cabin gets very hot in summer. Insulated wall and roof panels, such as PUF or rockwool-filled panels, reduce heat gain, so the AC cools faster and uses less electricity. A false ceiling or a roof with insulation also helps.
Choosing the right AC capacity
The right capacity depends on cabin size, insulation, sun exposure and how many people use the room. As a general guide, a small insulated cabin of about 100 sq. ft. often works with a 1 ton AC, while larger or heavily used cabins may need 1.5 ton or more. Ask your supplier to recommend the capacity for your site instead of guessing.
4. Extra fittings worth adding
- LAN and telephone points for offices
- Emergency light and space for a fire extinguisher
- Window grills and sliding aluminium windows
- Blinds or sun film to cut heat
- Water pipe and drain points if the cabin has a pantry or toilet
5. Common mistakes to avoid
- Not asking for a written specification. Always get the wire brand, wire gauge, MCB rating and flooring type in writing.
- Choosing low-grade wires to save cost. This is a safety risk and can lead to rework.
- Ignoring the AC load. A single socket circuit cannot run an AC safely.
- Selecting heavy flooring for a movable cabin. It can crack in transit.
- Skipping insulation. The AC will run longer and bills will rise.
- Forgetting earthing and the RCCB. These protect people, not just equipment.
6. What to ask your portable cabin manufacturer
- Which electrical items are included in the quoted price, and which are extra?
- What brand and gauge of wire and MCB do you use?
- What is under the floor finish, and can I change the flooring type?
- Is AC provision with bracket, drain and power point included?
- What panel insulation do you offer, and what thickness?
- Can the electrical layout be customised to my furniture plan?
- Do you handle delivery, installation and after-sales service?

Frequently asked questions
What electrical fittings should a portable cabin have?
A portable cabin should have a distribution board with MCBs and an RCCB or ELCB, concealed or conduit-run copper FRLS wiring, switches and sockets, LED lights, exhaust fans or a ventilation fan, and proper earthing. A separate power point for the air conditioner is also recommended.
Which flooring is best for a portable office cabin?
Vinyl or PVC flooring over a cement fibre board or plywood base is the most popular choice for portable office cabins because it is light, easy to clean and cost-effective. Vitrified tiles suit cabins that will stay at one site, while anti-skid or chequered sheets suit security cabins and industrial use.
Can I install an AC in a portable cabin?
Yes. Most portable cabins can take a split or window AC if the manufacturer provides a dedicated power point, a wall cut-out or bracket support, a drain provision and insulated walls and roof. It is best to confirm the AC provision while placing the order rather than adding it later.
What AC capacity is suitable for a portable cabin?
The capacity depends on cabin size, insulation, sun exposure and the number of people inside. A small cabin of around 100 sq. ft. with insulated panels commonly uses a 1 ton AC, while larger or heavily used cabins may need 1.5 ton or more. Ask your supplier to size it for your site conditions.
Why is insulation important when fitting an AC in a portable cabin?
Insulated wall and roof panels such as PUF or rockwool-filled panels reduce heat gain, so the AC cools faster and uses less electricity. Without insulation, a metal cabin heats up quickly in Indian summers and the AC has to work much harder.
Is electrical wiring included in the portable cabin price?
It depends on the manufacturer and the specification. Many portable cabin suppliers include basic wiring, lights and sockets, while AC points, extra fittings and premium flooring may be charged separately. Always ask for a written specification sheet that lists what is included.
How can I make a portable cabin electrically safe?
Use ISI-marked copper FRLS wires, MCBs and an RCCB or ELCB, complete earthing, and conduit or concealed wiring. Make sure the cabin's body is earthed, the load is matched to the supply, and the final connection is done by a licensed electrician.
Can portable cabins be customised with electrical, flooring and AC options?
Yes. Reputed portable cabin manufacturers in Pune offer customised electrical layouts, flooring types, AC provision, partitions, windows and interiors based on your size, budget and usage.
