i am instead of my kitchen outlets v GFCI. The inspector called me I simply needed to download one in ~ the first outlet in the circuit. I looked in ~ the outlets ~ above either side of mine kitchen; at one end both black and white were connected to the pack nodes (and no wires linked to LINE), and the outlet in ~ the other end of the kitchen had one wire linked to LINE, and also one linked to LOAD, yet neither LINE no one LOAD had actually both a black and also white connected.

What go this mean? Which side is the an initial in the circuit? was this also wired properly? just how should I attach my brand-new outlets?




You are watching: What is the difference between line and load

Line is the next of the machine where the wires indigenous the dashboard (or other tools feeding the device) space connected. Fill is where any kind of devices that room to be safeguarded by the GFCI maker are connected.

Most "newer" GFCI tools will not reset if they room not connected probably.

GFCI gadgets use a existing transformer (CT), come detect any current differences in between the "hot" and "neutral" conductors. The LINE terminals room on one next of the CT, if the LOAD terminals (and the receptacles top top the device) are on the other.

If girlfriend only have actually two wires one white and also one black the white connects come the silver LINE terminal and the black connects to the brass heat terminal the load terminals space only needed for protecting various other outlets downstream from that one . If you have actually a environment-friendly or bare wire it demands to connect to the green screw and the box if it is metal.

If you have both brass colored and silver toned screws on the an equipment being mounted then you need both warm (commonly black, red and blue depending on if you room wiring a 120 or 240 volt circuit black color is most frequently used for 120v and red is most common for the second hot leg of a 240v) and neutral wires (most often white). Existing travels under the warm leg(s) and also returns on the white leg. The green or (most often) bare wire is your ground and also sends the present to the soil via a collection of connections that ends at a rod that is driven deep into the soil by her meter or the ar where strength enters the house or business. It can also be base to galvanized cold water tube or metal electrical boxes mounted to the frame of the building. The "hot" wire(s) connect to the brass screw, neutral come the silver and also bare or environment-friendly wire come the eco-friendly ground screw. Power enters a GFCI from the panel on the next (don"t get confused here, by "side" they are referring to one of two people the peak or bottom set of screws because the circuit interrupted is situated in the middle where the test and reset buttons are located) labeling "line" and the present exits the GFCI from the side labeled "load". This basically installs a switch (similar come a irradiate switch that renders a rest in the circuit need to an appliance or device short circuit or overload and backfired down your wiring toward the panel. Quite than damaging her panel or leading to an electric fire the backfired electrical energy simply trips the move in the GFCI opened the circuit and preventing the power from traveling any type of further. So you only have to repair/replace the machine that led to the short, and also possibly the outlet that provided power to the quick circuited device.
