Default Line and Load side?


The conductors at Point D in Figure 307.53 are on the LINE OR LOAD side of the service equipment.

The conductors that are installed through the nipple into Panel D are considered to be on the LINE OR LOAD side of the service.

I'm very confused with the Line and Load side of things. Possibly just overthinking...

So the first picture, the wires are on the LOAD side of the disconnect but are on the LINE side of the Panel. Same thing goes for the second picture. So... Which is it? .

Maybe I just don't understand Service equipment. Would the Main panel be the service equipment or would it be the disconnect? I don't know, I'll stop talking... just confused...

Your point of reference determines line or load.

the question was more specific because it references the service equipment, and therefore gives you a point of reference.

look up point of service and give us your best shot, then someone will provide you with the answer.

Service point. This is the connection point between the serving utility facilities and the premises wiring.

Service equipment. This necessary equipment, which usually consists of circuit breakers or switches and fuses and their accessories, is connected to the load end of service conductors that serve a structure and constitutes the main control and cutoff of the supply. Service equipment does not include the metering equipment, such as the meter and/or meter enclosures (Sec. 230-66).

Reviewing these definitions should help you understand that service conductors originate at the serving utility (service point) and terminate on the line side of the service disconnecting means (service equipment). The following conductors and equipment on the load side of service equipment are considered feeder conductors:

------------------------------------------------

Okay so the point of service would end at the disconnect. So picture one, answer is Load and same with picture 2, Load.. Correct?

Your point of reference is (A). The answer is in your question.

The line is what is not bieng shut off. And the load is what will be shut off . In other words you have the wires coming from utility into a disconnect on the line side. Now when you put the disconnect on or off you are controlling the load. Your shutting off the load while the line side always has power.

Think of a receptical . The line would be the receptical and the load would be your tv. If you unplug the tv. The receptical still has power to it. The tv does not. Tv is the load
