    Hi All,

    I am replacing a fused Connection Module (Boiler) with a Grid module as shown below.

    The old module has following terminals:
    • Load L
    • Load N
    • Supply L
    • Supply N
    • Earth

    However, the new one has two seperate module, a fused module and a double pole switch.

    Can someone advise me wiring up the grid module?

    Does following wiring correct?

    NEW OLD
    ------- ----------
    L1 -------> Load N
    L2 -------> Supply N
    N2 -------> Supply L
    N1-L Shortcut -------> -
    Other L -------> Load L


    Any help would be appreciated, thanks.

    No not correct. You have switched live and neutral in the switch

    OK, does the following connection correct then?

    NEW OLD
    ------- ----------
    L1 -------> Supply L
    L2-L Shortcut -------> -
    Other L -------> Load L

    N1 -------> Supply N
    N2 -------> Load N

    If so, It's a shame that N1 and N2 are next to the fuse module. The wiring would tidier if L1 and L2 next to the fuse module.

    If by L2-L shortcut you mean connecting L2 to "other L" then looks ok

    If it bothers you that the neutrals are next to the fuse module swap them, they are grid after all, but tbh i wouldn't care

    Remember to connect cpc/earth and use appropriate sheath

    With modular accessories you need to create the desired arrangement. What you said in your second post is correct. Live feed and neutral feed in to the top of the dp switch, L1 and N1. Link wire from the bottom of the dp switch L2 to the top of the fuse, L. Then connect your boiler load live to the bottom of the fuse and the neutral on to the N2.
