Never ever use a mains plug/socket for low voltage stuff... the scope for something going horribly wrong is far too great. Besides which, if the OP thinks that a 50A Anderson is a bit "heavy duty" for his needs then he's definitely not going to be happy with a 32A BS4343D plug on its limit?
Seen people use blue /yellow mains round plugs and sockets?
I need to run a couple devices in my cab.
25 amp max draw.
What type of in-line power connector would you reccomend?
The 50 amp Anderson plugs are pretty compact, ideal for what you need imhoMaybe a bit heavier duty than what I need? Littlest one is rated to 50amp ?
