The ambient insulation rating of wires and cables is imprinted on the wire and cables. The labels on the cables will tell you the wire size, number of conductors and temperature rating of the wires and cables. The higher the cable and wire temperature ratings the higher the amount of current that is allowed to be drawn by the wire and cable according to the electrical code book.

What is the typical rating of a hot wire relay contacts?
The typical rating of a hot wire relay contacts is 35 amp
What is the amperage rating of 800 MCM Copper wire?
600amps
What size wire to pull 6 amps 70 feet?
NEC 310.16 conductor ampacities NEC 240.4(D) For residential installations the smallest wire to be used is 14 AWG (15 amps rating) and for commercial installations the smallest wire to be used is 12 AWG (20 amp rating)
What size wire 100 kva transformer?
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
What is the maximum current recommended for 30 gauge copper wire?
Sorry, there is no such wire size as "30 gauge" in the AWG (American Wire Gauge) system. For the ampacity rating of all standard conductor sizes, go to Table 310-16 of the National Electric Code. If you mean what wire size will carry 30 amps then a #10 copper wire insulation rating of 90 degree C is rated at 30 amps.
What does WSA mean in electrical terms?
Wire Sizing Amps
What size wire would be required for the power supply of a compressor at 45 amps?
8 AWG. <<>> Electrical code wire sizing for motors has to be at 125% of the rated motor current. So the wire has to have the ability to handle 45 + 11.25 = 56.25 amps. A #6 copper conductor with an insulation rating of 75 or 90 degrees C is rated at 65 amps.
How do you wire a 20 amp 2hp motor with 220 single phase with a safety switch?
A safety switch does not provide overload or over current protection. The safety switch is positioned just before the motor and just after the motor protection equipment. To wire a safety switch, the line in from the motor protection goes to the top of the switch and the motor load connects to the bottom of the safety switch. The switch must have at minimum of a 240 volt rating and have an amperage rating of not less than 30 amps. Wire sizing for the connection will be #10 conductor which has a rating of 30 amps.
What do the difference sizes allow between the various sq mm wires?
The different sizes allow for different current capacities to be carried by the wire. The larger the size, the more amperage capacity is allowed. The question refers to the metric sizing of wire. North American wire sizing is still done in AWG.
Can I run a 12 KW motor with a single phase?
To answer these types of questions, a voltage of the single phase motor should be stated. It has to do with the breaker sizing and wire sizing and current load.
What is the typical rating of a hot wire relay contacts?
The typical rating of a hot wire relay contacts is 35 amp
What is a typical rating of a hot wire relays contact?
The typical rating of a hot wire relay contacts is 35 amp
Is there Cable sizing calculator for a copper cable?
Here is a fine Wire Size Calculator. Scroll down to related links and look at "Wire Size Calculator".
Can aluminum 600v wire work a 40 amp breaker?
Wire size is rated by Amperes of current. You did not mention the wire size of the aluminum wire, so there is no way to answer your question. The voltage rating is more a rating of how good the insulation around the wire is.
If a wire has insulation that allows it to operate in a temperature of up 194 degrees Fahrenheit what temperature will the wire operate up to in degrees Celsius?
90 Degrees Celsius
How do you calculate mcb rating?
Circuit breakers are used to protect the conductor that is connected to it. The sizing of the conductor is based on the current of the load. As the connected load current is increased so must the wire size to accommodate that higher current. Therefore as the wire size increases so must the breaker size to accommodate the higher load current.
How do you relate ampere rating with copper wire?
The larger in diameter the wire is, the larger the current carrying capacity the wire has.
