Electrical equipment such as wiring, circuit breakers, Transformers, and such come in many different sizes with very different characteristics. The transformer, for instance, that feeds your home is much smaller than a transformer that feeds a large commercial building. Wires that feed a toaster are much too small to feed a large air-conditioner.
When an electrical engineer designs an installation, he must decide what size each element must be. He must consider the voltage present to be sure the gear is rated to withstand that voltage. For instance, a panelboard rated for 208/120V cannot be used in a 480/277V installation. A breaker or fuse must withstand a certain instantaneous fault current that may range from a few thousand amperes to several hundred thousand amperes. Is the wire big enough to safely carry the current required? All these decisions and many more may be involved in 'sizing' the electrical installation.
Wire Sizing Amps
When sizing electrical services, the first 3,000 VA is typically rated at 100% of its capacity. This means that for the initial 3,000 VA of demand, you would consider the full amount when calculating the total service requirement. For loads beyond 3,000 VA, the demand factors may vary based on specific codes or guidelines, often allowing for a reduced percentage. Always refer to local electrical codes for precise regulations.

When determining NEC conduit sizing for electrical installations, factors to consider include the number and size of conductors, the type of insulation, the ambient temperature, the conduit fill ratio, and the voltage drop.
When determining the appropriate sizing for a ground wire in an electrical system, factors to consider include the amount of current the wire needs to safely carry, the type of insulation on the wire, the length of the wire, and the specific requirements of the electrical code in your area.
