This is a voltage drop question and without a voltage the question can not be answered. As service voltages increase the wire size is allowed to be reduced. Assuming that the 200 amp service is for a home, the voltage of 240 volts will be used in the calculation.

A 3/0 copper conductor will limit the voltage drop to 3% or less when supplying 200 amps for 160 feet on a 240 volt system.

The code should be consulted on this installation as the utility company might not allow wires with no over current protection to come from the bottom of their meter to an underground service. There is a meter base in the market place that has an over current device mounted directly below the meter socket. This breaker will fulfill the requirement if the utility company says no to your original installation idea.

What size breaker do use for tnia 10?

For a TNIA 10 (Thermal Magnetic Circuit Breaker), the appropriate breaker size would depend on the specific requirements and rating of the circuit it is protecting. The breaker size should be chosen to match the maximum current rating of the circuit it is installed on to ensure proper protection against overcurrent. It is recommended to consult the manufacturer's specifications and guidelines for selecting the correct breaker size for the TNIA 10.


How do you wire a 100 amp breaker box and a 100 amp safety switch right from the power meter?

Installing a breaker box to the mains is a very dangerous proposition and should only be done by someone who knows what they are doing. It involved removing the meter so that the power is disconnected on the house side, Then the proper size and type of cable is run from the meter to the switch and then to the panel. 3 AWG copper or 2 AWG aluminum is required. The installation would also depend if this were a new additional panel or replacement panel.

When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?

When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.

What is the standard to select circuit breaker?

Add up your amps to calculate your breaker size. Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.
