Your wiring is definitely too small. As Steve and Will stated, you need
to double-up all of the wiring on the battery side of the speed control,
using two strands of 10 AWG wire (2.5mm diameter) for each connection or
a single strand of 8 AWG wire (3.3mm diameter). Also, make sure that
all of the connections are tight.
When it comes to wiring, the general rule is (a) keep it as short as
possible to reduce resistive losses and (b) never, never, never let it
run hot. Heat means that there is too much resistance (loss of power)
in the system.

Hi Frank,
Below are the pictures of my electrical setup. The outer wire diameter
of the Yellow wire is 3mm and the inner(stranded wires)diameter is 1mm
for the Black and Red wires: Outer D: 3mm with inner(stranded
wires)diameter of 2mm.

I plan to buy a higher capacity circuit breaker as suggested; about
50amps or more maybe. Maybe I need to lengthen my wires to reduce the
heat? or Parallel them?
Thanks,
Enzo

Both the circuit breaker tripping and the wires getting hot are a sure
sign that your electrical system is overloaded. What size wires are you
running:
a) From the battery to the fuse/breaker
b) From the fuse/breaker to the switch
c) From the switch to the speed controller
d) From the speed controller to each motor
and
e) what types of connections are used between those points?
With answers to those questions, we can spot the problem area and
recommend a proper solution.

Hi,
I use 2 pcs. 12volt 18ah SLA batteries in series for my 2pcs 24vdc
scooter motors and I bought this AC circuit breaker with a rating of
30 amps ,but the problem is it automatically turns off after running
tank for about 5 mins.
What type or rating of circuit breakers to use? Is it normal for my
wires to be hot?
Any form help will be greatly appreciated
Enzo
