single speed Posted January 18, 2015 Share Posted January 18, 2015 Has anyone got any pics or info on the internals of these? I think the breakers in mine may be shot, but before I rip it apart thought I'd ask you guys first! Quote Link to comment Share on other sites More sharing options...
fv1609 Posted January 18, 2015 Share Posted January 18, 2015 I might have something in an EMER but I need to know the official designation of your suspect unit. Quote Link to comment Share on other sites More sharing options...
single speed Posted January 18, 2015 Author Share Posted January 18, 2015 Hi It's distribution box no 1 mk1 fv157930 Thanks Quote Link to comment Share on other sites More sharing options...
fv1609 Posted January 18, 2015 Share Posted January 18, 2015 Ok glad you put the FV designation because there is Panel, Distribution, No.1 Mk 1 & also Box, Distribution, No.1 Mk 1. The Box repairs are in EMER POWER P 164/1 (Part 1) There is a circuit diagram on page 64 of this: http://hmvf.co.uk/pdf/ALL%20CHARGED%20UP%204%20ver4-1.pdf Bear in mind even when the circuit breakers are open there will still be through resistance of 165-191 ohms Unlike a trip switch they need a sustained period of overload 30A breaker 35A for 15 mins 60A for 15-50 secs 100A for 4-6 secs 10A breaker 11A for 15 mins 20A for 10-25 secs Quote Link to comment Share on other sites More sharing options...
