Whether you’re a bus operator, engineer, or contractor, you need to know how to make sure that your bus electrical system operates efficiently. Here are a few things to consider.


Providing high-reliability electrical systems requires proper equipment selection and design, as well as a high-reliability infrastructure. These are complemented by operational efficiencies and proper wiring and voltages. This is reflected in the maintenance and inspection policies that are implemented in the electrical system. The maintainability of bus electrical equipment is one of the most critical factors that determine the system’s ability to operate reliably.

Maintainability is defined as the probability that an action will be taken to perform maintenance under the specified conditions or procedures. It is also a function of redundancy and stock policies. If one component fails, the system automatically reconfigures itself to ensure that all components are able to perform their jobs. This is often achieved by selecting and using armored cables for increased fault tolerance.


Having an extensive vehicle maintenance program in place helps a school district stay on top of maintenance cycles. There are several key components to this program. Some of the most crucial include a comprehensive vehicle maintenance manual and a vehicle maintenance management system. Having a vehicle maintenance management system in place also helps a school district monitor repairs and replacements. The school district might not be able to replace every component on its buses, but it can ensure the safety and reliability of its fleet.

A comprehensive vehicle maintenance program is the best way to make sure your fleet is running in top shape. The best way to determine this is to perform a thorough inspection of the vehicle each year. Having a thorough inspection of the vehicle should include an examination of the vehicle’s key components, including electrical systems, steering, suspension, brakes, and air conditioning.

Low-carbon footprint

Compared to a conventional diesel bus, an electric bus has a 58% reduction in carbon footprint. Electric buses are also more cost effective on a lifecycle basis. In addition, a shift to zero emission buses will reduce emissions by over 1.4 billion tons.

Compared to a conventional diesel bus, a hybrid electric bus reduces embodied emissions by almost a third. The largest sources of emissions are from the body, chassis, and frame of the bus. The body and chassis account for over 50% of the bus weight. Steel and aluminium are the main metals used in the bus. They account for 16 tonnes CO2-eq and 2.24 tonnes CO2-eq per tonne, respectively.

The embedded emissions of buses accumulate to total fleet emissions. They are evenly allocated to each kilometre based on the lifetime of the bus. These emissions account for 67% of a bus’ carbon footprint. The battery accounts for approximately one-third of the embedded emissions.

AFCI breaker requirements

AFCI breakers are designed to interrupt the power circuit if an electrical arc occurs. The circuitry detects the current and voltage characteristics of arcing faults. The AFCI then shuts off the power supply to prevent an electrical fire.

AFCIs were designed in response to the U.S. Consumer Product Safety Commission’s report, “Residential Electrical Systems: A Problem in Many Homes.” It identified a problem in residential wiring systems that was responsible for a high number of fires and injuries in homes.

AFCIs are available in several configurations. There are single-pole and 2-pole AFCI breakers. Both devices should be installed to protect hot wires and circuits. They should be installed in locations where conventional circuit breakers are installed.

AFCI breakers should be installed in all rooms where arcing is likely to occur. In addition, AFCI breakers are required in all areas that are connected to a power source. This includes bedrooms, family rooms, dining rooms, and libraries. These rooms also include the laundry room and kitchen. AFCIs are also required for light switches in attic lighting.
