Office Cable Management Guide: Raceways, Trays and Power at the Desk
Short answer: Good office cable management has three stages: bring power and data to each row of desks through a floor box, wall feed or ceiling drop; distribute it along the row in a raceway with separate channels for power and data; and deliver it to each user through desk-level sockets, with spare cable hidden in a tray under the top. Decide this before the furniture is made and before the flooring is laid. Fixing it afterwards costs several times more.
Cables are the least glamorous part of an office project and the cause of the most regret. A floor box in the wrong place, a meeting table with no power, extension boards under every desk: all of these come from planning furniture and electricals separately. As workstation manufacturers we deal with this on every job, so here is the whole picture in one place.
Why does cable management matter?
- Safety. Loose cables are a trip hazard; overloaded extension boards are a fire risk.
- Reliability. Kicked plugs and strained connectors cause network drops and lost work.
- Appearance. A neat office looks professional to clients and recruits.
- Cleaning. Floors with trailing wires cannot be mopped properly.
- Flexibility. Organised cabling makes it possible to add or move seats.
- Performance. Data cables run alongside power cables can pick up interference; they should be separated.
Stage 1: How do power and data reach the furniture?
| Method | How it works | Advantages | Limitations |
|---|---|---|---|
| Floor box | A recessed box in the floor under or beside the desk run | Invisible; ideal for desks in the middle of the floor | Position must be fixed before flooring; costly to move |
| Raised access floor | Cables run in a void under removable floor tiles | Most flexible; common in IT parks | Higher cost; reduces ceiling height |
| Wall feed | Sockets or a conduit on the wall where the run starts | Simple and economical | Works only for runs that touch a wall |
| Ceiling drop (power pole) | A vertical pole from the false ceiling to the desk | No floor work; good for retrofits | Visible; needs neat placement |
| Floor trunking or cable ramp | Surface channel on the floor | Quick fix | Trip risk; temporary look |
| Skirting or dado trunking | Channel along the wall at skirting or desk height | Easy access; good for perimeter desks | Visible |
The key rule: the furniture layout decides the feed points. Every run needs its feed where the run starts. Share the furniture drawing with the electrical contractor before conduits are laid.
Stage 2: How are cables carried along the workstations?
| Component | What it does |
|---|---|
| Raceway | A metal or aluminium channel along the run, usually between facing desks or in the partition, with separate compartments for power and data |
| Vertical riser or cable spine | Covers cables between the floor feed and the raceway |
| Under-desk cable tray or basket | Holds adaptors, surplus cable and power strips off the floor |
| Partition with cable channel | Tile-based partitions carry cables at skirting or desk level behind removable covers |
| Hollow or cable-managed legs | Take cables down inside the leg |
Raceways can sit below the desk (hidden, sockets reached from under the top), at desk level, or above the desk in the screen (easiest to reach). Desk-level and above-desk positions are more convenient for laptop users who plug in every day.
Stage 3: How does the user get power?
| Option | Description | Best for |
|---|---|---|
| Grommet or wire manager | A capped hole in the top for cables to pass through | Basic, low-cost desks |
| Flip-up or pop-up power box | A recessed unit with sockets, USB, data and HDMI under a lid | Meeting tables, executive desks |
| Desk-edge or clamp-on power module | A socket strip fixed to the back edge of the top | Hot desks, retrofits |
| Raceway socket plates | Sockets and data ports mounted on the raceway at each seat | Linear and cluster workstations |
| Under-desk power strip | A strip fixed under the top, with cables up through a grommet | Budget installations |
| Wireless charging pad | Built into the top | Lounge tables, executive desks |
How many sockets per seat?
| Seat type | Suggested provision |
|---|---|
| Laptop user | 2 power sockets, USB charging; data port optional if Wi-Fi is strong |
| Desktop with one monitor | 3 power sockets, 1 data port |
| Dual-monitor or developer seat | 4 power sockets, 1 to 2 data ports |
| Hot desk | 2 sockets and USB at desk level, plus a dock |
| Meeting table | 1 power box for every 4 to 6 seats, with HDMI or USB-C at the screen end |
| Reception desk | 4 to 6 sockets, 2 data ports, access-control and phone points |
Add about 20 per cent spare capacity. Devices per person keep increasing. Have a qualified electrician calculate the circuit loading; furniture makers provide the pathway, not the electrical design.
Separating power and data
- Use a raceway with two or three compartments and keep data cables in their own channel
- Where they must cross, cross at right angles
- Do not coil surplus power cable around data cable
- Keep UPS power and raw power identifiable, with different coloured sockets
- Label both ends of every data cable
Planning sequence that avoids rework
- Finalise the furniture layout with seat numbers.
- Mark the feed point for every workstation run, table and counter on the drawing.
- List power and data points per seat.
- Hand this to the electrical and network contractors for load calculation and routing.
- Fix floor box positions, then lay conduits, then do the flooring.
- Manufacture furniture with raceways, cut-outs and trays to match.
- Install furniture; electricians and the IT vendor pull and terminate cables.
- Test every socket and port; fit covers; label.
Cable management for different furniture
- Linear workstations: central raceway with a riser at one end.
- L-shape and cluster desks: a central hub or cross partition carries cables to each seat. See our L-shape workstation guide and cluster and 120-degree workstations.
- Executive desks: floor box under the desk, power box on the side return, tray under the top. See the executive desk guide.
- Conference tables: floor box under the table centre, cables up through a hollow leg or riser to table power boxes. See meeting room types explained.
- Call centres: lockable raceways so connections cannot be tampered with. See call centre and BPO workstations.
- Sit-stand desks: a flexible cable spine and enough slack for the full height travel.
How to tidy cables in an existing office
You can improve a lot without replacing furniture:
- Fit under-desk trays or baskets and lift power strips off the floor.
- Screw power strips under the top and remove loose extension boards.
- Bundle cables with reusable hook-and-loop ties, not tight plastic zip ties.
- Add adhesive cable clips or a fabric sleeve down one leg.
- Cut grommet holes where cables currently hang over the edge.
- Use a cable spine from desk to floor point.
- Cover unavoidable floor crossings with a low-profile cable ramp.
- Remove dead cables and unused adaptors.
- Label what remains.
This kind of upgrade can be done over a weekend. See office renovation without shutting down.
Common mistakes
- Flooring laid before floor box positions are confirmed against the furniture drawing
- Power and data in the same compartment
- Too few sockets, leading to extension boards
- No power in meeting tables
- Raceways with no spare capacity
- Sockets only under the desk for people who plug in a laptop daily
- No access panels, so adding one cable means dismantling the desk
- Unlabelled cables
Workstations with cable management built in
We design raceways, trays, grommets and power-box cut-outs into the furniture at our Dhanori workshop and coordinate feed points with your electrician before production. See the office furniture range.
Frequently asked questions
What is a raceway in office furniture?
A covered channel running along a row of workstations that carries power and data cables in separate compartments and holds the socket plates for each seat.
How many power sockets does each workstation need?
Two for a laptop user, three for a desktop with one monitor and four for a dual-monitor seat, plus data ports as required and about 20 per cent spare.
Why should power and data cables be separated?
Power cables can cause electrical interference in data cables, and separation also makes maintenance safer and easier.
Can cable management be added to existing desks?
Yes. Under-desk trays, fixed power strips, grommets, cable spines and ties can be retrofitted without replacing the furniture.
