Find the wire from the secondary of the transformer. If it's a step-down transformer the thicker wire is the secondary. Measure its diameter in inches and calculate its cross-section area in square inches. The current rating for transformer wire is 1000 amps per square inch, or 1.55 amps per square mm.
(4 times the square root of 'A') centimeters.
2.75 * 10^-7 t
That would refer to the cross-section. A wire that has twice the diameter of another wire would have 4 times the cross-section - and therefore 4 times as much weight per meter, and 4 times as much current-carrying capacity.
The most sensible solution is to get a qualified electrician to check the wiring to see what the maximum load should be, and if necessary re-wire with higher capacity wire/configuration. You can (there is nothing physically to stop you), but whether it is a good idea or not is a totally different matter - you risk starting a fire if you do. The breaker amperage is set based on the wiring of the circuit - the wire used, along with how the wiring has been done, will limit the maximum current that can be allowed through the circuit; if this maximum is exceeded there is a risk of the wiring overheating and causing a fire.
n you run thhn wire in a cable tray
THHN wire is moisture resistant thermoplastic allowed for use in dry and wet locations. Maximum temperature is 60 C or 140 F. Being thermoplastic it should not be handled below 0 C as cracking of the insulation could easily occur.
It depends more on the insulation type not the voltage A very common wire type is THHN According to NEC (electrical standard popular in the USA) this type wire in size #12 is rated for 30 amps, but there is a footnote that states it can only be used for 20 amps maximum
yes
It is a fuse, a piece of metal wire, usually in a glass tube, that can only just carry the maximum allowed current. A current greater than the maximum allowed will melt the wire.
ampacity is 1.3 Amps
#1 copper thhn
yes
I would need more detailon your question but what i can tell you is 100' of #10 THHN eire is 8320grams with insulation and 7110 grams as bear copper wire. Now what i am trying to figure out is if that copper wire is 100% copper or not?
