Plug in RCD warm
Is it normal for plug on end of flex type RCD to have a warm spot?
This one has been in the tripped position for some hours after a 10 second power cut caused it to drop out and on going to reset it noticed the warm spot. Not enough to worry just surprised there would be any current flowing to produce any . No neons or other lights on to warm it either. GH |

If nothing apparent or if there are visible burn marks, ditch it. It can only get worse & may start a fire. |

Yes, if it had been in use in such a situation I would have put it down to that though in the situation it is used for it never carries more than 5 amps. This warm spot was with it tripped though so no load,and well away from the pins which were cold. Reckon it must come from one of the windings passing a small current even while tripped. Funnily enough one of your fellow flyboys asked a similar question about a very similar unit. https://forums.flyer.co.uk/viewtopic.php?t=112615 GH |
