[jiggin 4 fun]

I'm rewiring my wheelhouse and was wondering

if 10 or 12 gauge wire is too big?? (it is stranded wire)

I use two deep cell batterys wired in paralell

Here is a list of the things I use

(3) L.E.D. lights

Radio/CD player

Blower for heater (5 amps)

(1) outdoor light

(4) 1157 hole lights

T.V.

Thanks in advance

I THINK YOUR BEST OFF WITH THE HEAVIER WIRE. TAKE INTO ACCOUNT THE WIRE TRAVEL. YOU'LL BE HAPPY YOU WENT 10 GAUGE. THE HEAVIER WIRE HELPS WITH HEAT AND LINE LOSS.

Do you come off batteries to fuse box?Then to accessories.

From your battery use wires properly sized to supply a main terminal strip fuse or circuit breaker also properly sized to adequately supply the total calculated applied load.

The main fuse will then be used to supply all other branch circuit fuses. Each branch circuit fuse and wire shall be sized to adequately and safely supply the intended loads.

If you are not confused by what I just wrote, good luck. If you are confused then hire an eletrician so you don't start a fire.

Keep it safe - If you run 12 gauge fuse it at 20 amps. If you run 10 gauge fuse it at 30.
