according to CompTIA A+ guide to hardware Lab Manual:
"Any visible copper is an indication you need a new cable."

What sized of copper cable to replaced 240 square millimeter aluminium cable?
Copper is a better conductor by weight, but aluminum is better by weight, so the copper will be thinner but heavier. You will see that a 250 kcmil aluminium wire will get you 170 amps at 60 degC while a 000 (or 3/0) copper wire will get you 165 amps at 60 degC. I think you mean circular mils, not square millimeters.

Why are copper wires used in as connecting wires?
The copper wires used connect. Because conductivity of Cooper higher than aluminium but price of Cooper higher than aluminum. If compare between copper and aluminium cable can see at the same current rate diameter of aluminium cable is larger than copper cable.
Is stacking of cables in cable tray permitted?
See NEC Article 392. It depends on the voltage, conductor size and the type of cable tray selected.
Is gold cunductor of heat or electricity?
Gold is a good thermal conductor (looks like only copper and silver are better - see engineeringtoolbox dot com) Gold is also a good electrical conductor. Copper and silver are a little better, though.
What is the physical properity of copper?
Copper has a metallic lustre, and a reddish-orange colour when its surface is freshly exposed. It is soft, and a good conductor of both heat and electricity. Please see the link.
What size ground wire for a 400 amp panel in Quebec?
This answer is taken from the CEC. Table 17 states minimum size of grounding conductors. For a service conductor drawing 400 amps a #3 copper grounding conductor is needed. Also see rules 10-206, 10-700 and 10-812 if you have access to the code book.
Is copper a good conductor of heat?
Yes. Copper is an excellent conductor of heat. It is the second most heat conductive of all elemental metals, behind silver. Note that carbon in its diamond allotrope is far better at conducting heat than any metal - or anything else known. Copper is a superb metallic heat conductor. That's why you see it on the bottom of some cooking utensiles, or advertised as being clad between thin layers of stainless steel on the heating surfaces of pots and pans.
What is a thermal conductor metal?
Good thermal conductivity is characteristic of the metals. Some of the best conductors are silver, copper, gold, aluminum, nickel and iron. Please see the link.
Would tin be a good conductor?
Tin does conduct electricity, but it is only 15% as conductive as copper. See related link for a table of metals and their electrical conductivities. If you meant heat conductivity, then it is about 18% as conductive as copper. I'll post a link to that, as well.
Why is copper a better conductor than steel?
Only at low temperatures, at higher temperatures copper wouldn't be a better heat conductor than steel. The spring force is much tighter in the steel because its melting point is much higher, but at low temperatures its because it models something, like a rollercoaster, but no. Also Copper is more magnetic with its audience, which is the way. To test this out get some boiling water in a beaker and attach thermometer to the copper and steel and see which one heats up first.
