Choosing and specifying this item

Step up to this section and the reason is usually the route rather than the load. 4 mm² is most often specified for the dedicated circuit — a split-unit condenser on the roof, an instantaneous heater, a pantry appliance point, a distant pump — or for a circuit whose current would sit comfortably on a smaller conductor but whose length has already spent the permitted voltage drop.

The two things that change at this size

Termination. Stranded conductor at this section is normally crimped into a ferrule so that no strand escapes the clamp and the torque is taken evenly; solid is landed direct. The equipment terminal data and the panel builder's practice decide which, and it must be decided before termination day rather than after the board is tested.

Containment. The conductor is noticeably stiffer and takes more room, so the conduit that comfortably carried the lighting wiring will not accept the same count here. Fill allowance, bends between draw boxes and permissible pulling tension all tighten together.

Ask for, don't assume

Insulation compound and voltage class from the specification; the protective conductor size from the design rather than by symmetry; core colours to the project convention; and the longest joint-free run, so the packaging matches the pull instead of the total quantity.

Frequently asked questions

Why would a designer choose this section where a smaller one carries the current?

Usually voltage drop. On a long radial to a rooftop condensing unit, a distant pump or a detached building, the permitted drop across the final circuit is consumed by length before the current rating is reached, so the conductor is uprated. Grouping in a busy riser and high plant-room ambient push the same way. It is a design decision, so ask for the calculation rather than assuming the smaller size passes.

Do conductors of this size need ferrules at the terminals?

If the conductor is stranded, many terminals and busbar ways are specified with a crimped ferrule so no strand escapes the clamp and the clamping force is spread across the conductor. Solid conductor is landed directly. The equipment manufacturer's terminal data settles it, together with the panel builder's standard practice. Agree it before termination, because adding ferrules to an already tested board is disruptive.

Is this a suitable size for a split air-conditioning unit?

Frequently, but only the designer can confirm it for your unit. The circuit is sized on the manufacturer's full-load and starting current, the length from the isolator back to the board, the rooftop or ceiling ambient, and a protective device chosen to ride through the compressor's starting characteristic. Send the unit's electrical data with your enquiry and we will quote against what the design tells you to install.

What changes for conduit and draw boxes at this size?

Stiffness and cross-section both increase, so fill allowance is reached with fewer conductors and each bend costs more pulling tension. Runs that were acceptable with lighting wiring may now need a larger conduit, an extra draw box, or a gentler set at the change of direction. Confirm conduit sizes and draw-box spacing against the actual conductor count before first fix rather than during the pull.
