that

Indeed, until voltage drop bites and energy lost goes as heat.


That surely applies to any circuit?


But with LV lighting the currents stack up quick, as NT says a single
20W lamp no great shakes, few 50W on same circuit at nearly 4A a
piece, current climbs quick.


Low voltage high current can melt things nicely...


It's the current wot does this...


The voltage is mosttly harmless , but need to keep respect for the
current and its heating ability, with the cable and making sure
connectors are tight.
Have seen choc bloc melt down because of loose screws with LV lights.
