Ancor Marine Battery Cables: 4 AWG vs 2 AWG and Lug Sizes

Pre-assembled marine battery leads save the work of crimping large terminal lugs, but the ready-made cable still needs to match your electrical system. Ancor offers tinned-copper assemblies in different AWG sizes, lengths, colours and lug-stud hole diameters. Use this chart to compare the specific models carried by NewRVParts.

Three measurements determine the right assembly

Conductor gauge

The 4 AWG and heavier 2 AWG versions have different conductor cross-sections. Size for the circuit and route.

Finished cable length

Choose between an 18-inch or 32-inch assembly in this selection, with enough room for proper routing.

Lug-stud hole

Models with black insulation use 5/16-inch lugs here; red-insulated versions use 3/8-inch lugs. Check both studs.

All six products are pre-assembled with tinned-copper lugs and adhesive-lined heat shrink at the connections.

MPN Wire size Length Insulation colour Lug stud size
189130 4 AWG 18 in Black 5/16 in
189131 4 AWG 18 in Red 3/8 in
189134 4 AWG 32 in Black 5/16 in
189135 4 AWG 32 in Red 3/8 in
189140 2 AWG 18 in Black 5/16 in
189141 2 AWG 18 in Red 3/8 in

Ancor specifies fine-stranded UL 1426 marine battery cable, flame-retardant UV-inhibited insulation and adhesive-lined 3:1 heat shrink on this assembly family.

Installation and cable-size checks

Choose cable cross-section from the equipment's specified current draw, installation length and voltage-drop requirements, not simply the space available around the battery. Then measure the route including bends, strain relief and maintenance access. Verify stud diameter at both ends; do not force a 5/16-inch lug onto a 3/8-inch stud or assume that red and black cables share the same hole size.

Stud size and circuit protection are separate checks

Do not interchange the 5/16-inch and 3/8-inch lug arrangements without verifying the terminal connection. Battery leads must also be correctly protected, routed and secured according to the equipment manufacturer's electrical requirements.
