The following is from a separate e-mail I sent to Richard
Stone that I though the rest of the group might find
interest in. In this e-mail exchange, the US NEC was
referenced and so the following is based on the US NEC.

Hi Richard:
A number of good comments have been made.
I'm not sure anyone covered the fact that
two wires make a bundle, and therefore each
single in that bundle must be derated.
So, a single 10 AWG is good for 32 amps at
20 C. But, two 10 AWG wires in the same
bundle are only good for 31
According to the Belden wire table, 10awg carrying
32 amps will produce a 35C rise above ambient. And
according to them, the bundling factor is 1.0 for 1, 2,
or 3 bundled wires. If you're qualifying anything up
around 40C high temp, your wire's going to be 75C.
5C doesn't give you much ove

Group,
can you substitute one large wire 6 awg. ( handlles 63 amps. max )
for two smaller wires
Yes.

As a quick and simple answer, No. In a single fault condition, one cable
becomes lose / detached. The reaming 32 amp capable see the full 63 amps. The
result smoke, flame, etc.
Expressly forbidden in some standards and knocked out by others under the
single fault conditions.
Only way to do this i

They would 1/2 the current and disperse heat better.
The accepting screw terminal would allow for proper threading and tightness
of connection.
