20 AWG 3-core cable – 10 metre roll
3-core cable, 10 m roll
20 AWG = 0.50 mm²
This is the thicker 3-core roll, for single-colour and tunable white (CCT) LED strip tails where the connector will accept 20 AWG and the run needs more copper than 22 AWG. The thinner companion is the 22 AWG 3-core 10 metre roll (HL-3C-AWG22-10M).
Connectors and ribbon width
If you intend to use this cable with a solderless connector, check that the housing will take 20 AWG. Many compact 3-pin connectors are made for 22 AWG or 24 AWG and will not accept 20 AWG — 24 AWG is common on some of those clips. In that case use the 22 AWG roll if the housing will take it, or solder. A connector also has to match the strip width — a 10 mm clip will not seat on 8 mm or 12 mm tape. No connector works with every ribbon. Confirm both the wire size and the tape width, then test-fit. Matching 3-pin connectors are under Related Products; that list is not a guarantee of fit.
Voltage drop
Voltage drop must still be calculated. 20 AWG is better than 22 AWG for longer or heavier feeds, but it is not a licence for an unlimited run. Size the tail against the actual wattage and length. Inject power along the strip if the numbers are tight.
The common core on 3-wire tunable white
A typical CCT strip uses one shared positive (common anode) and two returns — warm white and cool white. The colour cores only carry their own channel. The shared positive carries the whole strip.
Example: 14.4 W/m 24 V tunable strip, 5 metres, both channels fully on:
- Total load: 14.4 W/m × 5 m = 72 W
- Current at 24 V: 72 W ÷ 24 V = 3 A
That 3 A is in the common core. You cannot run extra length because one colour channel looks lightly loaded. Size the cable against the combined current.
Core colours
Product images are for illustration. Core colours can vary; this cable is supplied from mixed stock. Do not expect the delivered colours to match the photographs. Identify each core with a meter before you terminate.
