EmmienLightFan Posted August 23, 2016 Share Posted August 23, 2016 (edited) I am running two 12v WS2811 strips off of a controller on which everything else is 5v. I know I need to link the grounds of the 5v supply and 12v supply, but should I link them with thick wire as if they are carrying the current of the strips, or can I use some thin wire?

Mr Grunts Posted August 23, 2016 Share Posted August 23, 2016 Better to go thick. Thin wire tends to burn out when a possible surge happens Link to comment Share on other sites More sharing options...
George Simmons Posted August 23, 2016 Share Posted August 23, 2016 Thick. The thicker, the better. At least, according to a conversation I once overheard women having at a bar ... 1 Link to comment Share on other sites More sharing options...
Dave Batzdorf Posted August 23, 2016 Share Posted August 23, 2016 IMO For DC circuits the ground should always be the same as the HOT. For AC circuits, if 3-wire it can be one gauge less than the hot-neutral lines. for 2-wire should be same as HOT. Link to comment Share on other sites More sharing options...

Our electrical system here in the UK works slightly differently. Will the wire actually be carrying any current? Link to comment Share on other sites More sharing options...
