When choosing wire, current dictates the size of the conductor and voltage dictates the insulation. Current causes the wire to heat up due to resistance. Metal expands and contracts when heated and cooled. This expansion and contraction, if too large, can loosen connections. Loose connections increase resistance, cause more heating, and will eventually ...

I'm sorry, but from the tone of your question, and the fact that you even suggest plugging this motor into a regular 15A receptacle tells me you are so far over your head your only valid option is to hire a pro to wire this. This is NOT a simple DIY job and you cannot simply ask questions to get every little detail out of an internet message board to do this ...

As others have stated, the voltage of the appliance/circuit has no bearing on the size (gauge) of the wire. Voltage dictates the quality of the insulation of a wire and most (power) wire we encounter will be rated for 600 Volts. The gauge should be primarily selected by determining the current draw - in Amperes - of all the devices to be connected to the ...

Improper Electrical Wiring constitutes a serious life safety hazard. It can be the source of structural fire and potentially fatal shocks. I am not saying that you can't splice a common electrical wall switch into an extension cord. I am saying that it is not a good general practice. Consider Instead Installing a suitable hardwired outlet and wall ...

Breaking the tab on the neutral side does exactly the same as the hot side: it separates one terminal and neutral outlet from the other terminal and outlet. I can't imagine a scenario where only the neutral would be cut. The neutral should be cut where the corresponding hots are cut and come with their own neutral. For example, if the two halves of the ...

There are collar boxes available that have conduit KO's (knockouts). Just install one on top of the existing device box and run your conduit. This one is even better as it has more volume: Brand: Steel City, Part number:531511234UB Here is a raised device cover to be used with the 4x4 box shown. They can be had in any number of different ...

It might be important to add a photo of a plug, so us Yanks can understand what you're talking about. Based on the image it's clear to see that the terminal screws have no heads, so it's much different from most screw terminals a US user would come across. Terminals like this; even in the US, are designed to clamp a straight bit of wire. With a terminal ...

The general guidelines: Don't notch a joist. (it's legal under the correct circumstances, but don't consider it until you have no other choice.) Don't drill a joist near the ends. (how near is near? Stick to the middle third and be safe. ) Only drill on the center-line of the joist. (This is the area under least stress). keep your holes less than 1/3 ...

I assume you are in the USA. The heater is probably a pure 240V load with no need for the neutral (white) wire. you should simply cap the white wire with a wire nut and tuck it back into the electrical box.

My understanding is that I need a 1 phase(household) to three phase converter to do this. Yes. Usually these are used if you need to control the speed, torque, or another aspect of the motor. If you just need a constant 1750 RPM with a max 1HP, then you can purchase a single phase AC motor that doesn't require a converter. If you need to control the ...

18g stranded wire is quite common on arms 14g stranded is often used to join the 18g arm strands, and to tie into the ceiling. This applies to North America and normal chandeliers with relatively low (<50 each) wattage bulbs.

If this receptacle you are referring to is serving the kitchen counter you CANNOT use that to feed a disposal. Kitchen counter circuits cannot be used to feed fixed appliances. You will need to run a new feed to the disposal, preferably a dedicated circuit from the panel.

Your method is fine. If your area has adopted the 2011 version of the National Electrical Code, this method allows you to wire the circuit using 2 wire cable instead of 3 wire cable. A change to the code now requires a grounded "neutral" conductor at all switch locations that control lighting loads. National Electrical Code 2011 Chapter 4 ...

It looks a bit of an unusual setup, but I'll hazard a guess that there is either a further light on the circuit either fed from one of the switches or the power from the circuit is fed in at a switch and feeds on from here to another light (or lights). (Obviously, you need to verify this, as we can't tell how it's wired from just one photograph). From left ...

The National Electrical Code (NEC) determines the required minimum size for conductors. Under the NEC three broad categories cover most installations: low voltage, less than 600 volts, more than 600 volts. Keep in mind that code requirements specify the worst legally allowable construction. One common reason to increase conductor size above code minimums ...

In addition to the comments about this being something you need to work out as people rather than trying to slap a technological fix on... if this really matters to you, you could offer to pay the heating bill out of your own pocket, or to pay a larger share of it, since you're the one who wants to spend more on fuel.

Don't do it! If the devices are on separate circuits, you cannot "tie" them together. If you're in the USA and use single phase service, you've likely turned a 120 Volt circuit into a 240 Volt short-circuit. You've directly connected the two legs of the service, causing a short-circuit. The switch is intended to control three branches of a single ...

OK, first of all, plainly this is a mess. The fact that there is a white wire hooked up to a black wire without any recolouring of it alone says that (1) there's some amateurish stuff going on here, and (2) you cannot trust any of the white wires to actually be neutral until you prove that they are. So proceed cautiously, and take notes as you go. There ...

Both black and red are typically used to indicate hot. Though you can't be positive without actually testing it with a multimeter. Red is usually used when there are two hots (14/3 wire instead of 14/2). Both green and bare copper are used to indicate ground. So it sounds like you wired it correctly. The green wire from the line (source) should also be ...

Yes, you can use this. GFCI breakers combine two different functions into one device. The circuit breaker function of the device is rated for 50 amps. However, because your 15 amp breaker is upstream from the GFCI, your circuit is protected at 15 amps, and will trip at 15 amps if there is a fault either before or after your GFCI. The GFCI function on the ...

Any thoughts? Plainly something is messed up. I have many times taken apart a switch and discovered that the previous homeowner was creative in their choices. A recent one: white was hot and black was neutral, ground was open, the switch was wired to interrupt the neutral, the white wire from the lamp was connected to the black wire from the wall, and ...

In addition to the other answers which correctly note that it is hard to block magnetism, it is a very bad idea to run power and data together because some unfortunate person in the future -- possibly a future version of yourself -- is someday going to try to hang a picture and drive a nail through the wire, just nicking both the data and power cables enough ...

I don't know too much about replacing outlets, only what I've read online or through YouTube videos. That's a good start but I would strongly recommend that you learn more before you make potentially safety-impacting changes in your electrical wiring. In particular if you cannot immediately state the relationships between amps, volts and watts, if they ...

If you're in the US, NEC likely applies. Article 402 covers fixture wires, and explains what types and sizes are allowed. Type Table 402.3 lists the types of wires allowed to be used as fixture wires. If you're going to rewire the fixture, you'll have to use a type of wire listed in this table. FFH-2 HF, HFF KF-1, KF-2, KFF-1, KFF-2 PAF, PAFF PF, PFF ...
