120mm
The recommended conduit size for a 200 amp service is typically 2 inches in diameter.
50 mm or 2 inch will handle the 3/0 wires for a 200 amp service.
For new 200 amp services the conduit size should be 3 inch PVC.
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.
No, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the conduit.
Service wire required is AWG # 3/0 copper.
200ma is .200 amps or .2 amps
The wire to conduit chart provides information on the maximum number and size of wires that can safely fit inside a conduit based on the conduit size.
A #10 copper wire with an insulation factor of 90 degrees C is rated at 30 amps. If you need the full 30 amps for the load use a #8 copper wire. Loaded to 80% of rating will give you 32 usable amps.
The maximum amperage capacity of a Siemens breaker rated at 200 amps is 200 amps.
A conduit size chart for wire provides information on the recommended conduit size based on the wire gauge and the number of wires being used. It helps in determining the appropriate conduit size for safe and efficient wire installation.
To convert watts to amps, you can use the formula: Amps = Watts / Volts. In this case, to convert 200 watts at 12 volts to amps, it would be: 200 watts / 12 volts = 16.67 amps. So, 200 watts at 12 volts is approximately 16.67 amps.
