running 20a 240 to a separate junction box In my garage I have wiring for a 240V outlet. It is a four-wire setup (two hots, one neutral and one ground). It is set up on a 20 ampere double breaker in the circuit breaker box. I want to remove that outlet and install two . That is dangerous, there should be a connection between the audio ground and the metal chassis. However, the connection could be a low value resistor and/or a diode bridge.

In my garage I have wiring for a 240V outlet. It is a four-wire setup (two hots, one neutral and one ground). It is set up on a 20 ampere double breaker in the circuit breaker box. I want to remove that outlet and install two . I am installing a 120v/20A 12K mini split. I plan to run the line to a 240v disconnect box. I also want to run a separate line (120v/15A circuit) for an exterior outlet near the unit. I .
two separate circuits to box
They are claiming that as long as I junction the 18-2 into a 14-2 NM-B before it goes into my switch box then I don't have to separate the high and low voltage in the box. I .
There are instances where I tied the three hots together and just ran one circuit, but Code limits you to 13 outlets on a 20 amp circuit when you count the 180 volt amps. So often that gets exceeded if you try to meld a .
Hey everyone, I am planning on running 20A 120v and 20A 240V circuits on 10/3 BX surface mounted gang boxes (except DC on dedicated 10/2), I would like to run 3 separate .Advice on wiring electrical junction box with easy to follow junction box wiring diagrams, including information on 20 and 30 amp junction boxes. Be sure which type of junction box should be used for ring main, radial circuits and lighting . Ok, so the two hot wires in one 12/2 go to separate breakers and feed two 12/2 lines after the junction box. Per your explanation, they're sharing a neutral and ground and that is . GFCI circuit breakers offer extra protection, and they may be required in situations where there is an increased risk of shock, such as with circuits that are used around water .
NEC doesn't allow 2 separate circuits run to an out building. It can be a multiwire circuit supplying both 120V/240V which technically gives you two 120V circuits but is fed by . Currently I have a 20 AMP double pole breaker supplying 240v to an electrical baseboard (12/2). I want to remove the the baseboard, and instead add two 20 AMP outlets in .First, it's fine to run multiple receptacles off a single 240v circuit right? I want two receptacles for my bandsaw and table saw. They'll never be used at the same time. They pull just around 10a each, give or take, so I was going to run a 20a circuit w/ 12awg THHN. I was planning to run a separate circuit for my dust collector, also 240v. How I run the hot wire (conduit, etc) will depend on the location of the junction box, I suppose. 4. The neutral wire from Run 1 10-2 wire goes into a second junction box inside Shed 1. 5. The ground wire from Run 1 10-2 goes into same second junction box in Shed 1. 6. The hot wire from Shed 1 12/2 20 amp interior wiring is attached to the .
Hey everyone, I am planning on running 20A 120v and 20A 240V circuits on 10/3 BX surface mounted gang boxes (except DC on dedicated 10/2), I would like to run 3 separate 10/3GA 20A 240V circuits with a 240V 20A and 120V 20A receptacles in a gang box (no daisy chaining boxes).
(Because when a 120V generator backfeeds a 120/240-9600V poletop transformer, the voltage on the backside of the transformer is, guess what! 9600 volts. That's how transformers work.) Even worse, it sounds like rather than running a 120/240V /3 cable, he was using two separate cables to backfeed each leg separately. What a hokey-dokey rig.In our breaker box there's a 240v breaker for the old furnace that we no longer have. Can I convert that to 2 120v circuits and run that to the shop? I know I want 2 separate circuits to run power tools lights and a small heater without making the lights flicker and tripping the breaker. Figured a 240 would be plenty.Through the crawl space you likely can run 8/3 NMB, and a junction box to conduit or whatever to run under the driveway. Look up Ask This Old House. Last year they helped a guy install a proper sub-panel in his garden shed, for his EV charger.
Could I just swap the 30A two-pole breaker in the house with a 20A two-pole breaker? Bringing the entire circuit down to 20A and eliminating the need for a sub-panel in the shed. The lights and receptacle in the shed would run off of a single 20A circuit. I won't be using anywhere near 20A in the garage or shed in the near future.
I want to run five 20A 120V circuits and one 20A 240v circuit from my panel (13 circuit carrying conductors, 6 grounds), through a 25' long conduit in my crawlspace, to a junction box where I then splice those in to romex. . If it happens to be the case that it makes sense to have them go to separate junction boxes at the far end rather than . The 30 Amp 120/240 circuit is wired with 10/3 from the panel to a surface mounted receptacle behind the kitchenette appliance. I'm thinking of replacing that receptacle with a junction box. From there, run a 12/2 to a standard receptacle for the microwave, and another 12/2 to another receptacle for the refrigerator.Excellent info from u/the_blue_wizard.. Most kitchen counter receptacles were 3-wire split-15 prior to code changing to require a minimum of two 20A circuits, but code still permits the addition of a split-15, so long as it is supplied by a single breaker with two poles and either GFCI protection if in a kitchen, AFCI breaker if elsewhere in the house.
splitting 240v into two lines
extending 240v line
Hi all, I'm not an electrican and I'd like to put a 240v 30A and a 120v 20A circuit into my garage. I have space in my breaker box for both and I'm going to have a pro come out and make the connection, but I'm trying to save a bit by running the cable myself.
Yes of course. All the usual rules for junctions and splices are in play. The box needs to be of an adequate size and type, the box must be readily accessible, the type of splice must be correct and of the correct sized wire and type, etc etc. But there is nothing in particular that is wrong with having a junction box for a 30A 240V circuit.Wiring 240V pump . other I’m running power about 600ft on a 20A isolated circuit to a 240V, single phase, 16A irrigation pump. Thinking I’ll use aluminum URD for direct burial. . Or should I have a separate junction box to change to Cu? Unincorporated area, no permitting restrictions for something like this. I just don’t want to burn . Hi guys. Thanks for the feedback. My assumption was there would be no issues with a junction box as well. However, I'm getting a quote from an electrician stating he'd need to run a new line from the panel. He's citing section 26-744 if the OntariobElwctrucal Safety Code. I am running 10 AWG THHN through conduit to multiple junction boxes. I terminated the connections at the junction boxes using romex and I'm running the romex behind the wall to the outlets that are above the junction boxes. I have been using 10 AWG romex from the junction box to the receptacles but it's caused a few of my outlets to sit crooked .
Ok, so the two hot wires in one 12/2 go to separate breakers and feed two 12/2 lines after the junction box. Per your explanation, they're sharing a neutral and ground and that is OK. They basically just did that to run less wire (3 lines to . Nothing is worse than tripping the breaker and plunging into darkness with your fingers 2” from a spinning blade. Also, outlets cannot have larger than a 20A breaker, so if you ever want to provision more than 20A of service out there, e.g. For a dust collector, you'll want a second circuit and therefore a sub-panel. Demand can sneak up on you.Kitchen receptacles need a 20A circuit as well. But the sink light doesn't, or the garbage disposal, or the under cabinet lights. So there may be a 2 gang junction box containing switches and receptacles on separate circuits. Another example in the kitchen. This is fine with me but the HVAC crew is running a 18-2 conductor to a junction box directly under the switch that controls the exhaust fan. They are claiming that as long as I junction the 18-2 into a 14-2 NM-B before it goes into my switch box then I don't have to separate the high and low voltage in the box. I have never heard of this.
I’m wondering if code allows 10-3 wire in a junction box containing 12-2 wire from a different circuit? I’ve run out of room to install a separate junction box for a 10-3 splice that was taped together. I’m trying to correct the problem as it was left taped outside of its required junction box. Thank you!
But it would be protected by the fused disconnect. Basically 60A breaker at panel to a junction box near the unit outside, junction box feeds 20A fused disconnect and 50A fused disconnect. 6GA THHN wires for the run from breaker box to junction box, and junction box to disconnects. Well, you can run two totally separate circuits to the box, from two toally separate single-pole breakers. That way if one trips, the other does not. Nothing wrong with that. You can also run a "Multi Wire Branch Circuit" (MWBC) from a two-pole breaker (a fault on either will shut both down) with a single neutral and two hots.
Run a 12/2 and a 12/3 from the panel to the box. Remove the old heavier gauge wire. Run the 12/2 to the outlet, run the 12/3 to the stove. If you need a 40 or 50 amp breaker for a stove, just make sure you get the correct gauge wire (this will be the 3 wire) or else as mentioned before your wires will overheat and start fires. The existing junction boxes that terminate this conduit run are 4 11/16" by 2 1/8" square boxes, with 42 in3 of fill. While more than adequate for your existing run, which only takes up 36.25 in3 of fill at each end (8 12AWGs, 8 14AWGs, and a 12AWG grounding allowance), this isn't enough space for any of the proposals you are floating, never .
The existing wiring to a proposed new water heater will come up about 2-3 feet short. The way it's currently run it offers zero slackage to work with. There is no easy shorter route to rerun the existing wiring to get any additional length. Can some sort of junction box be installed in order to gain the required length that will be needed? This is in an unfinished basement area .
It is 3700 W load against the upper limit of 3800 for the Mysa. 3700W on a 20A 240V circuit is fine but its near the upper limit as well. 2) You don't have #1, you have two circuits, one 240V 20A 2P breaker, and one 240V 15A 2P breaker. The Mysa is a single pole switch. You need two poles to interrupt two separate circuits. I'm hoping to run 1/2 of it to a new 20A GFCI, with the load side then going down to another 20A receptacle below the new counter (as shown on the photo). The other leg I'd like to run from the GFCI box (i.e., using the GFCI box as a junction, there's plenty of room) to an adjacent room where I also need a new pair of 20A receptacles (a work .
