What size cable for 210 amps?
The recommended cable size for 210 amps would be at least 2/0 AWG (00 AWG) for optimal performance and safety. Make sure to consult the National Electrical Code (NEC) or a professional electrician to determine the exact cable size needed based on the installation requirements and conditions.
What is the cable size for 700 amps?
The cable size for 700 amps depends on several factors, including the type of cable (copper or aluminum), the installation method, and the permissible voltage drop. Generally, for copper conductors, a cable size of around 2/0 AWG to 3/0 AWG is commonly used, while for aluminum conductors, sizes may range from 250 kcmil to 300 kcmil. It's essential to consult the National Electrical Code (NEC) or a local electrician for precise requirements based on specific conditions.
What is the the basis for cable tray sizing to NEC?
The sizing of cable trays in accordance with the National Electrical Code (NEC) is typically based on the maximum allowable fill capacity of cables within the tray. The NEC provides guidelines on the maximum fill capacity based on factors such as cable type, size, and insulation. It is important to follow these guidelines to ensure safe and efficient cable management within the tray.
How many amps will 16 gauge stranded auto wire handle?
According to NEC, it's max rating in free air is 18 amps.
What is the minimum size grounding conductor?
Sizing of ground conductors is based on the load capacity in amps of the generator. There is a table in the electrical code book which states an amperage and what size ground wire that is needed for that amperage.
What size cable for 210 amps?
The recommended cable size for 210 amps would be at least 2/0 AWG (00 AWG) for optimal performance and safety. Make sure to consult the National Electrical Code (NEC) or a professional electrician to determine the exact cable size needed based on the installation requirements and conditions.
How calculate the cable size when give current?
The NEC has a table that shows what size cable to use with each amperage and where it can be used.
What is the cable size for 700 amps?
The cable size for 700 amps depends on several factors, including the type of cable (copper or aluminum), the installation method, and the permissible voltage drop. Generally, for copper conductors, a cable size of around 2/0 AWG to 3/0 AWG is commonly used, while for aluminum conductors, sizes may range from 250 kcmil to 300 kcmil. It's essential to consult the National Electrical Code (NEC) or a local electrician for precise requirements based on specific conditions.
What is the current rating of 185sqmm?
It is 350 mcm cable and Table 310-16 1996 NEC gives limiting values of 260 amps at 60 degrees C up to 350 amps for 90 degrees for copper, or 210/280 amps for aluminium.
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.
What is the the basis for cable tray sizing to NEC?
The sizing of cable trays in accordance with the National Electrical Code (NEC) is typically based on the maximum allowable fill capacity of cables within the tray. The NEC provides guidelines on the maximum fill capacity based on factors such as cable type, size, and insulation. It is important to follow these guidelines to ensure safe and efficient cable management within the tray.
What size cable to run 8kw shower 50 meters from main supply?
8000 watts divided by 240 volts equals 33.3 amps. If using NM cable indoors, Table 310.16 of the NEC says #8 wire is good to 40 amps. However, since this is a heating application which would qualify under "continuous duty" classifications(3hours or more of run time), then you figure it as 125%. This would in turn bump you up a wire size to #6. 33 amps times 125% equals 41.6 amps. Voltage drop would not be an issue even with #8 copper.
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 is power cable size 10kW 3 phase motor with 415V?
The formula for amps when kilowatts are stated is; kW x 1000/1.73 x Volts x pf. 10 x 1000/1.73 x 415 x .8 = 10000/574 = 17 amps. The electrical code states that motor feeders have to be rated at 125% of the motors FLA (full load amps). 17 x 125% = 21 amps. A #10 copper conductor with an insulation factor of 75 or 90 degrees C are both rated at 30 amps.
What minimum size-grounding conductor is required if the circuit protection ahead is rated at 500 amps instantaneous?
For a circuit protection device rated at 500 amps, the minimum size of the grounding conductor is typically determined by the National Electrical Code (NEC) tables. According to NEC Table 250.122, for a circuit with overcurrent protection of 500 amps, the minimum grounding conductor size required is 3/0 AWG copper or 250 kcmil aluminum. Always ensure to check local codes and regulations, as they may have additional requirements.
What size of copper wire can carry 30 amps?
Couple of things wrong here. 30 isn't a wire size. If you mean a wire that can carry 30 amps that would be # 10. Now it depends on how many # 10 wires you want to put into a conduit that governs the size of the conduit.
If service is fed with service entrance conductors of 500 MCM THHN copper and fused at 400 amps What would be the minimum size of a copper grounding electrode conductor?
For a service rated at 400 amps using 500 MCM THHN copper conductors, the minimum size for a copper grounding electrode conductor (GEC) can be determined using the National Electrical Code (NEC) guidelines. According to NEC Table 250.66, for a service of 400 amps, the minimum size for a copper GEC is 4 AWG. However, if the GEC is connected to a ground rod, it must be a minimum of 6 AWG copper.
