How can i calculate amperes for transformers?
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.
When a wire is bent to form a square its area becomes A square cm square What is length of the wire?
(4 times the square root of 'A') centimeters.
A square wire loop 11.0 on each side carries a clockwise current of 16.0 Find the magnitude of th?
2.75 * 10^-7 t
Why wire size in square mm?
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.
Can you add another appliance to a circuit by simply changing breaker to a larger amperage?
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.
Can you run thhn conductors exposed?
n you run thhn wire in a cable tray
What is the temperature rating of THHN WIRE?
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.
Can you run 8 gauge thhn wire for 30a circuit?
Yes, you can use 8 gauge THHN wire for a 30 amp circuit. This wire size is sufficient to handle the current safely and meets the requirements of the National Electrical Code. Just make sure to follow all applicable codes and standards when installing the wiring.
What is the maximum amps for 12 gauge wire?
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
What a safety device that melts if the current is too big?
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.
Can thhn wire be run exposed in a plenum rated ceiling for grounding?
yes
What percent of copper is a 1O THHN Electrical Wire?
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?
Is THHN oil resistant?
No, THHN wire is not oil resistant. THHN wire is primarily designed for dry locations and is not recommended for use in areas where it may come into contact with oil or other chemicals. If oil resistance is needed, you may want to consider a different type of wire designed specifically for that purpose.
What is the maximum current carrying capacity of 16 swg copper wire?
12 swg current carrying capacity
What is type THW wire?
Thw...thermoplastic heat resistant wire building wire type. In most applications replaced by type thhn which has a smaller od and
Why is the magnetic force on a wire at a maximum when the wire is perpendicular to the magnetic field?
When the wire is perpendicular to the magnetic field, the force on the moving charges in the wire is maximized because the magnetic field exerts a force perpendicular to both the field and the direction of current in the wire. This results in the maximum Lorentz force acting on the charges in the wire, leading to the maximum overall force experienced by the wire.
What is the weight of 500 mcm thhn wire per foot?
2.2 lbs per ft
