154 Chapter 6
The engineer must provide a load summary of the total connected load (amps/watts) for all items
shown on the power and RCP drawings. This ensures that the main service is adequate. Many cities and
towns have energy-conservation regulations regarding electrical loads. The engineer’s drawings must
abide by all codes and bylaws pertaining to the city, town, or province where the project is located.
The following are typically included in a set of electrical drawings:
- Type and location of outlet, (duplex, dedicated, isolated ground, GFI, etc.)
- Size and type of conduits (data, communication, phone)
- Volts of switches, wiring, and circuitry
- Lamps and model numbers of light fixtures
