Receiving electrical cable: a delivery inspection checklist

PILONE CABLES TECHNICAL TEAM · UPDATED 22 OCTOBER 2026

Check the delivery against your written quotation before you sign for it: the description, size, cores, sheath print, supplied length, packaging and paperwork.

Most delivery problems are mismatches, not bad copper: the wrong core count, a 45 m coil where 90 m was quoted, a strand code where a mm² size was agreed. Those you can catch at the gate in ten minutes. What you cannot catch by eye is conductor quality; that needs a resistance measurement or a test report, and the checklist below says which is which.

Before the cable arrives: what to have in hand

You can only check a delivery against something written down. Keep the final quotation or order open on your phone, with one line per cable showing the items below. If a line is missing, ask the supplier to confirm it in writing before dispatch, not after the cable is on site.

What each order line should state, so the delivery has something to be checked against.
Item on the quotationExample of a complete entryWhy it matters at delivery
Cable type and conductorCopper, flexible (class 5) or stranded (class 2)Flexible and standard cable look alike on a coil
Nominal size2.5 mm², or 7/.029 with the nominal mm² statedA strand code alone does not fix the nominal size
Number of cores3 coreThe most common delivery mismatch
Insulation and sheathPVC/PVC, voltage rating 450/750 VShould match the sheath print
Supplied length per package90 m per coil, 4 coilsA coil is packaging, not a fixed length
Quantity and unit360 m totalLets you total what was delivered
Delivery address and dateSite address in Lahore, agreed dayWho receives and signs

If you have not ordered yet, the quotation checklist lists what to ask for, and price per metre, foot or coil shows how to put two quotations on the same unit.

The checklist at the gate

Work through these with the delivery still on the vehicle or just unloaded. Note anything that does not match on the delivery note before signing.

Delivery checks you can do without instruments. A pass means the delivery matches the order; it does not certify the cable.
CheckHowWhat a mismatch looks like
1. Count the packagesCount coils or drums against the order linesFewer coils, or two lines delivered as one
2. Read the label or tagCompare product description, size and cores with the quotationA label for 2 core on a 3 core order
3. Read the sheath printUnroll a metre and read what is printed along the cablePrint that disagrees with the label, or no print at all
4. Count the coresLook at the cut end: count insulated cores and note the coloursWrong core count, or no earth core where one was ordered
5. Check the conductor buildFlexible has many fine strands; standard has a few thicker onesSolid or coarse strands where flexible was ordered
6. Look for damageCrushed or cut sheath, kinks, flattened coils, wet packagingAny cut through the sheath, or water inside the packaging
7. Check the paperworkDelivery note or invoice lists the same lines and quantitiesPaperwork describes a different size or length
8. Note the length to verifyRecord which coils you will measure (see below)—
Damaged cable should not be installed. A cut or crushed sheath can let moisture reach the insulation. Photograph the damage, note it on the delivery note, and raise it with the supplier before the cable goes in the wall.

Checking the supplied length

A coil is packaging, not a standard length, so check the length your quotation states rather than assuming one. There are two practical ways:

MEASURE ONE COIL

Unroll and tape it

Unroll one coil on a clean floor in measured lengths (a marked 5 m or 10 m run works) and count. If one coil is short, ask before checking the rest.

USE THE METRE MARKS

If the sheath is metre-marked

Some cables are printed with running metre marks. Subtract the reading at the inner end from the reading at the outer end. Not every cable carries these marks.

Convert carefully if the quotation is in feet or yards: 1 ft = 0.3048 m and 1 yd = 0.9144 m exactly, so 300 ft is 91.44 m and 100 yd is 91.44 m. Compare length with length, never a coil count with a metre count.

What visual checks, weight and the QR code cannot prove

Matching a delivery to the order is worth doing, but none of the gate checks proves what the conductor is made of or that the cable meets a standard.

The limits of quick checks.
CheckWhat it can showWhat it cannot show
Colour and shine of the copperThat the conductor looks like copperPurity; copper-clad or alloy conductors can look similar on a fresh cut
Strand countThe conductor build (flexible or stranded)The cross-section is large enough; thinner strands give the same count
Weighing the coilA gross difference from the weight your supplier statesConductor area on its own: insulation, sheath and packaging are in the weight too
Sheath printWhat the maker declaresThat the declaration has been independently tested
QR code on the boxThat the code leads to the maker's own record for a batchThe length of this coil, the conductor quality, or that a code was not copied onto other packaging

Pilone boxes carry a QR code that opens a product record showing the cable size, batch number, manufacturing year and conductor. Compare what the record shows with the box and the sheath print. It helps you spot packaging that does not belong to the batch it claims; it is not a test of the cable inside.

When you need more than a visual check: resistance

The meaningful check on a conductor is its resistance. IEC 60228 sets a maximum resistance per kilometre at 20 °C for each nominal size and conductor class, and a conductor that measures above it is not that nominal size, whatever the label says. For example, the limit for a 2.5 mm² class 2 conductor is 7.41 Ω/km, so one core of a 90 m coil may measure no more than about 0.67 Ω at 20 °C.

Values that small are near the floor of an ordinary multimeter, whose own leads and contacts add a similar amount, and copper reads higher when it is warm. A reading worth acting on needs a low-resistance (four-wire) measurement and a temperature correction. The full table of limits, a worked example and what Pilone can and cannot measure are on cable testing: what can and cannot be checked. Whether the metal is copper at all is a separate check, described on how to check the conductor yourself.

Frequently asked

What should I check when cable is delivered?
Check the delivery against your written quotation: the number of coils, the label, the print along the sheath, the core count at the cut end, the conductor build, any visible damage and the delivery note. Note any mismatch on the delivery note before signing. Then measure the length of at least one coil.
Does the QR code on the box prove the cable is genuine?
No single check proves that. A QR code shows the maker's record for a batch, so you can compare the batch printed on the box with the record. It does not measure the cable inside, its length or its conductor, and a code can be copied. Treat it as one consistency check alongside the sheath print and your quotation.
Can I check copper quality by weighing the coil?
Only roughly. A coil's weight includes insulation, sheath and packaging, so weight alone cannot tell you the conductor area or purity. A large difference from the weight your supplier states is worth asking about. A proper conductor check is a resistance measurement with a low-resistance ohmmeter, corrected to 20 °C.
Coil kitne meter ka hona chahiye?
Coil ki koi ek fixed lambai nahi hoti. Jo lambai quotation mein likhi hai wohi check karein: aik coil khol kar naap lein, ya agar sheath par meter ke nishaan hon to dono siron ka farq nikal lein. Feet mein quote ho to 1 foot = 0.3048 meter se badlein.
What should I do if the delivery does not match the order?
Do not install the mismatched cable. Write the difference on the delivery note, take photos of the label, sheath print and cut end, and send them to the supplier with your quotation the same day. A clear record of what was ordered and what arrived makes the correction straightforward.

Order with every line written down

Send the cable type, size, cores, metres and delivery address for each line. We reply with a quotation, and that quotation is what you check the delivery against.
