with 2 or more generators connected in series, so that any increase in power demand can be met.

In parallel, with all 4 generators connected to the same part of the split bus bar. Power is then shared along

 In parallel, with one generator at a time supplying individual parts of the split bus bar.

An electromotive force that moves the electrons in an electrical flow. It is measured in Volts (V).

The charge capacity of a battery. It is measured in Ampere hours (AH).

An electrical resistance divided by an electrical voltage. It is measured in Watts (W).

The flow of electric charge per time unit. It is measured in Amperes (A).

allow a person to take a sample of the fuel and to empty the fuel tank for maintenance.

remove particles and impurities from the fuel that could damage the engine.

allow atmospheric pressure to enter the fuel tank in order to avoid a vacuum.

allow the excess fuel to flow out of the tank after refuelling.

The generators will overheat and fail.

The electrical line could overheat and cause a fire.

The fuse may blow.

The bypass line will be activated.
