It specifically defines an electrical service as any part of the distribution from the utility point of entry to the first voltage-related over-load device, typically the main circuit breaker. For your home, the utilities that require an electrical service are the electrical appliances such as refrigerators, air conditioners, ovens, microwaves, and hot water heaters; electrical wiring; and the electrical components like transformers, fuses, electrical outlets, and termination boxes. In addition, any wiring within a building that serves as a means of escape should also be considered electrical as well. In other words, anything that can potentially be an electrical hazard needs to be properly marked with an electrician from this link.
The basic components used to discern whether a utility or building is able to qualify as an electrical service property are: Type of utility, number of appliances served by the utility, and the utility’s rating for total load. To figure out the load, simply multiply the number of appliances by the current consumption rate per hour. This figure will then be multiplied by each individual appliance and the total load in a circuit. The rating for total load indicates the maximum amount of electricity that an appliance can continuously draw. The lower the load rating, the more utility power generated by the appliance.
Next, look at the overall structure of your electrical system. Will there be a major distribution point such as a mains switch or large cable? Mains switch allows utility power to move to critical circuits and handle heavy loads. A cable connects multiple appliances and the circuit breakers provide the path of utility power. Identify the location of your main electrical service size and style.
Wire sizes fall into two categories: stranded and insulated. Sized wiring provides sufficient space to connect both conductors without creating an overload and keeping the breakers free from interference. Insulated wire provides protection against excessive voltage and excessive current. Both are often pre-bundled with your main service size. If you require additional protection, there are stranded and insulated wire options available from your electrician. Insulated wire is also an option for under the siding of your house.

Next, consider the variety of utilities and appliances you will be servicing. Many times the number of 120-volt service wires used to serve one outlet is much more than the number of 240 volts used to supply five outlets. As a result, you may need to install a separate three-pronged electrical service structure. Other times, you will only need one outlet for a variety of electronics. Your service technician can help you evaluate your outlets and determine the best solution for your needs. In these cases, the number of three pronged electric sockets usually ties the electrical service size to the main power size.
Finally, consider the amount of amp draw your electrical service panel needs. If you are servicing an RV or marine application, the amps may need to be increased to account for the extra amps needed by the marine equipment. If you service the electronics in a data center, the need for high amp draw will be less, since the data transfer will not require as many amps. You may read more here!
