need to ground metal box
The ground screw in the back of the metal box is tapped #10-32 and any short 10-32 machine screw will suffice. They sell little green "ground screws" if you're fancy. So go down to the "wire sold by the foot" section and buy yourself 1' of green or bare #10 solid THHN wire.What is the appropriate way to bond a metal junction box containing a receptacle .
If you need to wire a ground, you can use that hole, use a grounding clip, or drill .

In most cases the socket will pick up ground off the metal box and no ground wire is needed. The conditions for that involve a receptacle marked "Self-Grounding", or hard flush . I initially plan to just use the EMT conduit and metal box as ground without running ground wire, but some people here recommend running one ground wire just for another level of protection. As shown in the picture, there . Ground to the metal box first. The metal box should always be grounded. If you need to ground 2 or more wires, then use a pigtail and wire nut. The receptacle may not need . 2-wire NM cable with a bare ground was never allowed by code for a 120/240 volt dryer circuit, not even back in 1956. I would recommend you replace that circuit with 10-3 NM .
Yup, ground wire from the cable must go straight to the ground screw on the metal box. The outlet will pick up ground automagically via the steel domed cover. Just make a J-hook anyway you can, and put it on the green . Ground wire attached to green grounding screw in the box. All ground wires pig tailed and the ground screw on the outlet is attached to the rest of the ground wires. What .
The ground wire should be bonded with all other ground wires and bonded to any metal junction box or enclosure. The ground wire must also be attached where there is a ground terminal or . You don't need a wire to ground the switch, the mounting screws satisfy the requirement when used with metal boxes, and there is an exception that allows you to not satisfy grounding requirements if no grounding means .
I have a new 240v line I’m running to a metal 4gang box. It’s going to be for a dryer outlet. The outlet itself has its own ground. Does the metal box also need to be grounded or just running .I was really confused by the way it was wired up, so I looked up their manual and verified that the wiring on the dryer did in fact match the manual. According to the manual on their website, the neutral wire terminal has a wire connecting it to the chassis were the ground wire is connected. So ground and neutral are directly connected at the . Plastic doesn't generally need a knockout, but a larger wire (in the US, 240v wire is 3-line cable, which means its larger) will have a harder time going into the box past the plastic barbs that are designed to hold the wire in place. You can buy plastic boxes without barbs, but you'll have to secure the wire within 8" or so of the box. older dryers no electronics all 240 volt gear dryer came with frame bonded wire ran back to panel and fastened to to netral/ground bar no big deal. new dryers are 240 heater elements and drum motor only with 120 volt ciruit boards for electronic and lights, Now we have need for nuetral. 3 wire okay ciruit for antique equipement but now using 3 .
This can be done when there is no ground in the box. It works because the ground and neutral are connected back in the main panel. However, there are problems, such as if the neutral wire back to the panel fails, suddenly, the outlet ground is at 120 volts (through the load, out the neutral pin, through the wire to the ground pin.This is why the US National Electric Code Article 250 requires the ground wire to also be tied to the neutral wire at the service panel . To follow the current path—the current flows through the appliance ground wire to the breaker box where it joins the neutral path. The current becomes too high at this point and the breaker trips. This .
Since the box is grounded through the conduit (which is as good a ground conductor as any), you don't even have to terminate the ground wire to the box as long as the Z-wave switch has a metal yoke that contacts the box, although you can get a grounding screw (any 10-32 machine screw will do in a pinch), screw it into the back of the box (there .
From there, you can then run a separate ground wire (green #12 THHN or bare #12 copper works, provided it's not subject to physical damage) back to a suitable grounding point (i.e. another suitably sized equipment grounding wire, the wire that connects the panel to the grounding electrode system, or back to the panel, but not to a water pipe .
The reason for the 4-prong outlets on newer dryers is to provide an additional level of safety. The fourth prong is a dedicated ground wire, separate from the neutral wire, which helps to eliminate the risk of shock in case the neutral wire becomes damaged or loose. In multiconductor building cable, the ground wire does not have insulation. It can't to avoid touching things which should be grounded, like the metal box. Remember, neutral is not ground, and there may be a voltage differential between neutral and ground. That could cause arcing in a metal box which is grounded otherwise. The 3rd wire is neutral not ground,, and if ground is present, it must be separate from neutral. As long as the existing dryer connection is 4-wire, or is 3-wire with insulated neutral and solid metal conduit back to the panel, then it may be extended. Use a junction box extension, or a surface conduit system like Legrand Wiremold. The wiring to the receptacle is hooked up correctly: Hot (black) to brass, Netural (white) to silver, and bare ground to green. The metal box does not have a ground screw, so it depends upon the contact with the receptacle to make it grounded. I made a final continuity check, before turning on the power, to make certain nothing was shorted.
A switch leg from the switch enters the box and is spliced to a fixture wire. A neutral is spliced to a fixture wire and carries on through the box. The two fixture wires (14 AWG) supply a luminaire. A fixture stud and a fixture hickey are installed in the box. All conductors are 12 AWG in metal raceways entering the metal box. In the junction box I can see the ground coming out of the outlet. See the image: So where is the ground wire inside the outlet? I'd like to know how this is handled. Update: for some reason I didn't notice ground attached to the neutral. But it is there. Then I noticed a orange label and found the instruction:FWIW I did wire it up for a quick test as originally posted, using the bare ground as a bootleg neutral and everything worked fine. But alas, code exists to prevent hazards. I assume in a perfect world it would be fine, but if a single "what if" happened, I might melt .
This looks like all new work, and I assume that is MC cable. If that cable has a ground wire, you need to use it and not just depend on the metal sheath for a ground path. Now, if you are installing a NEMA 10-30 (neutral not .Usually on a range you will have either two hot wires and a ground on older homes and some newer ranges need two hot wires, a neutral and a ground. This bare wire is not suitable to be used as a neutral wire if a neutral is needed. If .
When a 3-wire range ties neutral to ground, what it is doing is supplying neutral in the normal way, and then bootlegging ground. This is a "legal bootleg" owing to an exception in Code at 250.140. The rationale is that these connections are rarely disturbed, and this will avoid interrupting appliance sales to underequipped locations.The wiring was run 30ish years ago before using the bare ground wire as neutral was illegal. It has 6 gauge black and white hot wires and a 10 gauge bare conductor that is run to the ground in the breaker box. . The supply circuit is 120/240-volt, single-phase, 3-wire; or 208Y/120-volt derived from a 3-phase, 4-wire, wye-connected system. .
Screwing a wire to a metal box isn't exactly "ground". E: I agree with u/jes3001, you should be in touch with an electrician. Nothing there is standard. . Chicago requires EMT in residential, so you should hire an electrician to get a neutral wire into that box. Using the ground as a neutral is an unsafe practice.This. Think of 3 prong vs 4 prong dryers. 3 prong dryer uses the neutral to 'ground' the chassis vs the 4 prong using the ground wire to ground the chassis. With 3 prong dryers if the neutral opens up/becomes disconnected, your dryer chassis now becomes live. Before you ask 'why even bother 'grounding' the chassis to neutral in a 3 prong dryer .
Metal conduit is used as ground, but you need to run metal conduit all the way to the welder receptacle, since no ground mounting in that box. Ground and neutral must be separated in sub panels. They are only connected in the main panel. . ground wire meaning from the old subpanel to the main? The new subpanel with the circuit will have hot .
First of all, it’s important to know where your shop is. It’s likely that you need GFCI protection, which might be easiest by using GFCI breakers. According to US national code, you can and should use a 2-pole breaker for 2 separate circuits when sharing a neutral. Basically, you’d run a 3-wire plus ground romex (black, red, white, bare). Since you converted the existing main panel to a subpanel, the exception no longer applies. Now most inspectors in my area will allow us to use white tape to cover the bare neutral, especially if pulling a new 4-wire would cause extensive damage to the dwelling. They don't have to do this, but they use a little common sense.And now instead of a nice backup low impedance path through a nearby ground wire, or metal conduit/Romex ground/etc, leading to an overcurrent fault, you have a medium impedance path through a lightbulb, the neutral wire, the drill, the human holding the drill and actual earth ground, that is drawing 2A and slowly cooking the poor human. You don't need a wire to ground the switch, the mounting screws satisfy the requirement when used with metal boxes, and there is an exception that allows you to not satisfy grounding requirements if no grounding means exists for replacement switches.. What sends up warning flares is in your question you made it sound like you just blew off the grounding .

It helped their case that most 3-wire connections go back to the main service panel, where neutral and ground are bonded. The failure of the neutral wire would have the effect of electrifying the chassis, but that was reasoned to be "a risk worth taking" since these connections are rarely disturbed. Even today, all ranges/ovens and dryers can .
The circuit was run illegally with 6-2 cable with ground, and they are likely illegally using the bare ground wire to connect to the Neutral terminal of your NEMA 6-50 outlet. This was NEVER correct no matter how old. A NEMA 6 10-50 outlet was supposed to be 2 Hots + Neutral, no ground. You cannot use a bare ground wire as the Neutral. Will it .
