Wireing for 240v Sentry Garage unit shore power

[apcheval]

I am almost finished the fit out of my boat and need to install shore power. I have bought a Sentry 5702sP1 Garage kit which is pre-assembled with RCD and 2xMCBs and contains RCD 40A 30mA, MCBs 1 x 16A and 1 x 6A as shown below.

I am fairly competent in wireing fuse boxes, plugs and sockets but not too sure about the wireing for the RCD. I am OK with the live feed and earth cables but wonder if there is an electrician out there who can tell me how to wire the negative feed.
Cheers Alan

Hi Allan

Im a spark to trade. The incomming live and neutral need to be connected in one side of the RCD and the out going live and neutral (thats the cables going to the neutral busbar and the live busbar on the circuit breakers) in the other side.

The operation of the RCD depends on monitoring the current flow in the live and neutral and tripping if it sees a difference in excess of 30ma.

Hope this helps

Cheers

Colin

Hopefully colinmi has helped you with the wiring but referring to the "neutral" as the "negative" rather indicates you are not as competant at wiring as you are telling us.

(Stricly its not even called the neutral now!)

Thanks for that info, and yes I was trying to link a file from my computer and that is why it did not work. As I am out of time to edit this post I may relist with a picture to make it clear what I am requesting.
Ref your comment, I may have referred to the "neutral" as the "negative" but what is important is to recognize that I was referring to the blue wire. I do consider myself as competant having spent 5 years as a prototype wireman and have completely wired out from new, 2 boats one being a 30 foot yacht and the other a 40 footer of which both are still in commission with no known electrical faults.
