Supply voltage decides which lead can be used at all. Site work runs 110V through a transformer and a 230V lead will not connect to it. Both are held, and the plug and socket colour identifies which is which before the rating is read. A lead used on the wrong supply is not a risk so much as an impossibility, since the plugs do not mate.
Cable section matters more than length and is the thing most often overlooked. A 1.5mm² cable carries less than a 2.5mm² one, and a long lead on thin cable drops voltage so a tool at the far end runs slower than it should even though it runs.
Length and socket count are chosen against the working area. Reels here run 10m, 15m, 25m and 50m with 2 and 4 sockets, and a reel has to be fully unwound at full load because a coiled cable under load heats within its own coil. Socket count also decides whether one reel serves a bay or a second lead has to be run.
Thermal trip and RCD forms address that and the wider risk. A thermal trip cuts the reel if it overheats. An RCD cuts the supply on a fault, which is what protects the person rather than the cable. Retractable reels wind themselves in. Send the site to 07754288583 on WhatsApp. Boxed and cassette reels change how the reel is carried rather than what it supplies.
