    Upgrading Windlass wire - double up on the wire

    House Batteries: US Batteries L16CH 6v - 420Ah x 2, so 12V 420AH About a year old, batteries equalized regularly as per US Battery recommendations and current SOH = 98% (Balmar SG200) Start Batteries: Magnacharge 65-1100 AGM (SLA) x 2 (in parallel). CCA: 850, CA: 1075, RC: 150 Batteries have...

    Upgrading Windlass wire - double up on the wire

    Hi Stu, Appreciate your feedback. Please note I understand electrics, but not necessarily from a boat perspective. The wire size calculations were done using the Blue Sea wizard and based on a a 5% voltage drop. However the wire length ended up longer then anticipated and it appears relying on...

    Upgrading Windlass wire - double up on the wire

    That is the plan, same length, gauge, and type of cable. 2AWG can handle 200A, so plenty, and will use a 200A MRBF, or less, so that is safe. Two runs of 2Awg would be equivalent to 2/0, not 4/0. I suspect neither 2/0 or 4/0 can be connected directly to the windlass, even the 2Awg was tight to...

    Upgrading Windlass wire - double up on the wire

    We recently redid the wiring on our Dickerson 37 sailboat and ran 2awg from the batteries to the windlass. 2 AWG was chosen based on a 5% voltage drop. However appears the cable run is slightly longer than planned and possibly the terminations are adding to voltage drop. Appears the real voltage...
