Final answer:
Electrical distribution systems can be dangerous, but using circuit breakers, a three-wire system, ground fault interrupters, and isolation transformers can help minimize the risks.
Step-by-step explanation:
Electrical distribution systems can be dangerous, but there are several measures that can be taken to minimize the dangers. Here are some ways to do that:
- Use circuit breakers and fuses to interrupt excessive currents and prevent thermal hazards.
- Implement a three-wire system that utilizes live/hot, neutral, and earth/ground wires to guard against thermal and shock hazards. The neutral wire and case of the appliance should be grounded.
- Install ground fault interrupters (GFIs) that detect the loss of current to unintentional paths and prevent shock.
- Use isolation transformers to insulate the device being powered from the original source and prevent shock.
These are some of the systems and devices that can help minimize the dangers associated with electrical distribution systems. It's important to follow proper safety protocols and consult professionals when dealing with electrical systems.
