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.
What is the maximum current capacity of a 15amp wire?
The maximum current capacity of a 15amp wire is 15 amps.
Can you run thhn conductors exposed?
n you run thhn wire in a cable tray
What is the maximum current rating for a 20A wire gauge?
The maximum current rating for a 20A wire gauge is 20 amperes.
What is the maximum current rating for an 18AWG wire?
The maximum current rating for an 18AWG wire is typically around 16 amps.
What is the maximum current capacity of a 20 amp wire?
The maximum current capacity of a 20 amp wire is 20 amps.
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.
What is the appropriate wire size for a 125 amp circuit using THHN wire?
For a 125 amp circuit using THHN wire, the appropriate wire size would be 1/0 AWG.
What is the maximum current rating for a wire that can safely handle 10 wire amps?
The maximum current rating for a wire that can safely handle 10 wire amps is 10 amps.
What is the recommended wire size for a 100 amp circuit using THHN wire?
The recommended wire size for a 100 amp circuit using THHN wire is typically 3 AWG (American Wire Gauge).
What is the maximum current rating for an 18 AWG wire?
The maximum current rating for an 18 AWG wire is typically around 16 amps.
What is the maximum current that an 18 AWG wire can handle?
An 18 AWG wire can typically handle a maximum current of around 16 amps.
What use is THHN wire suitable for?
THHN wire is suitable for use in residential and commercial electrical wiring applications, such as powering outlets, switches, and lighting fixtures.
