What is upstream and downstream breaker?
In Electrical Distribution, upstream and downstream refers to “Incoming” and “outgoing” circuit breakers. Regarding your question on supply and load of circuit breaker, there is no supply side and load side in present circuit breakers. and supply and load connections can be reversed.
Where should a sub panel breaker be installed?
Quote from the video:
Quote from Youtube video: You're going to be adding a subpanel always add the largest panel that that is practical to a door if you were thinking that you needed six circuits.
Does a sub panel need a feeder breaker?
The subpanel may be equipped with a main breaker to allow for power interruption without having to go back to the main panel, but it is not required to have a main shutoff circuit breaker, since the feeder breaker back in the main panel serves this function.
Can main breaker be at bottom of panel?
Just about all modern electric panels can be mounted upside down, meaning that the main breaker is located at the bottom instead of the top.
How do you know if its a line side or load side?
Load Wire – Generally connected to the top half of your switch. If the wire is coming from the top of the switch box, it is likely your load wire. Line Wire – Generally connected to the bottom half of your switch. In some cases, line wires are marked with “line”, “pwr”, or a lightning bolt symbol.
What does upstream and downstream mean?
Upstream refers to the material inputs needed for production, while downstream is the opposite end, where products get produced and distributed.
Does it matter where breakers go in a panel?
There really isn’t a code issue on where to install various breakers, but most of what you said is a preference. Best practice is to install the highest rated breakers as close to the main as possible. Other than that, its mostly a preference.
Can you install a subpanel upside down?
Most of the time is dictated by installed breakers – including the main. If any handle operates up-down there is likely a proper up side. If all handles operate left-right it is likely able to be mounted either way.
What is the 6 disconnect rule?
The rule is six disconnecting means for each service, not six service disconnecting means per building. If the building has two services, you can have a total of 12 service disconnects (six disconnects per service).
What happens if I reverse line and load?
Quote from the video:
Quote from Youtube video: When line and load are reversed at a newer gfci outlet the behavior is pretty simple you'll be able to trip the gfci. But it won't reset. With older gfcis. The outlet will trip but the outlet remains.
Which side of circuit breaker is load?
The load side is where the power leaves the device (or electrical box) and travels down the circuit.
Does the hot wire go to line or load?
Line Connection
The circuit’s hot wire (typically colored black or red) connects to the black or brass-colored screw terminal marked LINE. The white neutral wire connects to the silver-colored screw terminal marked LINE. The markings for line and load usually are printed on the back of the outlet’s plastic body.
Which wire is hot if both are black?
Here’s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
What happens if you reverse line and load on GFCI?
GFCI’s contain a lockout feature that will prevent RESET if: • There is no power being supplied to the GFCI. The GFCI is miswired due to reversal of the LINE and LOAD leads. The GFCI cannot pass its internal test, indicating that it may not be able to provide protection in the event of a ground fault.
Is the black wire load or line?
So, what color is the load wire? Load wires are mostly black, but red can also be used as a secondary load wire. They are also connected to the switch’s top half, while line wires are connected to the switch’s bottom half.
Can you put a GFCI at the end of a circuit?
You will need to install an end-of-line GFCI receptacle if you are installing a jacuzzi. Ground fault circuit interrupter (GFCI) receptacles are designed to prevent electrical shocks by automatically shutting off power to the receptacle if the device detects an imbalance in the current.
How do you test line vs load?

Quote from Youtube video: On use the non-contact voltage tester.
