RCDs (GFCIs) vs DC

[gnubie]

A bigclive youtube clip that mentions the effects of DC flowing through an RCD/GFCI that is not rated for DC applications. I've mentioned DC vs RCDs in passing on the forum quite some time ago. Once upon a time you only need to be worried about DC from external sources but with the increasing amount of crappy things from China etc being used there is now a real risk of there being DC flowing around your premises wiring. Some people may find the clip useful.
