Choosing and specifying this item

What actually decides the size

Five cores at 16 mm2 each puts this cable in submain territory: three phases, a neutral and a protective conductor carried at the same cross-section as the phases. That full-size earth is the reason a five-core is specified where a board needs its own protective conductor rather than a combined PEN upstream. The cross-section on its own never settles the selection. Start from design current, then apply the derating factors that GCC installations punish you for ignoring: ambient temperature in roof voids, plant rooms and unshaded trays, grouping with other circuits, the installation method, and soil thermal resistivity plus backfill on buried runs. Voltage drop is a separate check against the measured route length, and on long submains the drop, not the thermal limit, usually forces the next size up.

Settle these before requesting a quotation

Insulation sets the permitted conductor temperature and therefore how much current the same copper will carry, so PVC and XLPE are not interchangeable choices at this size. Voltage designation must match the system class in the specification. Length should be stated as drum lengths or cut lengths, because joints on a submain are a design decision. Armour, sheath material for escape routes, and conductor class all follow, since lug and gland selection depend on them.

Frequently asked questions

Why specify five cores instead of four?

The five-core arrangement carries the three phases, the neutral and a dedicated protective conductor inside one sheath, with the earth at the same cross-section as the phases. That matters on a submain feeding a separate distribution board, where a combined PEN is not acceptable and a reduced earth may not satisfy the earth-fault loop calculation. If the design routes the protective conductor separately, a four-core is the correct choice instead.

Can I take a tabulated current rating and apply it directly on a Riyadh project?

No. Tabulated ratings are stated at a reference ambient and a reference installation method. Plant rooms, roof routes and exposed trays across the Gulf sit well above those references, so correction factors for ambient temperature, grouping, installation method and, for buried cable, soil thermal resistivity all have to be applied before the cable is coordinated with its protective device. Voltage drop is then checked separately against the real route length.

What information do you need from us before quoting?

The insulation type the design assumed, the voltage designation the specification calls for, and the length, stating whether you want continuous drum lengths or cut pieces. It also helps to confirm whether armour is required, what sheath material the route demands, the conductor class for terminations, and any approval regime the consultant will check the submittal against, so the offer is made against your specification rather than a generic one.

Does the same cross-section still work if the run gets longer?

Not automatically. Thermal capacity and voltage drop are two independent checks, and on long submains the drop limit usually governs first. Calculate the drop at design current over the measured route, including risers and slack at both terminations, before assuming the cross-section holds. If the result is marginal, moving up a size is far cheaper than re-pulling, and gland and lug sizes should be revisited at the same time.
