Q:how do you connect two copper wires together

You have your choice. Some choices depend on the use of the wire. You can solder them, join them with crimp connectors, use wire nuts, or use screw down terminals. If the wire are for electrical house wiring, wire nuts are requires. If for low voltage inside equipement or the like, any of the listed methods will work fine.

Q:have 0 gauge power wire, but don't have a ground wire! can I use the power wire as a ground wire if I cut a piece off?

0 gauge? you probably have 14 awg, and yes, you can cut off a piece and use it as the ground strap, but you would be better off to use an actual ground wire, because later on if someone goes to work on that outlet they could miswire the new one. EDIT whoops, just saw the category, i saw this question on the main page, i was thinking home AC...not car audio, my bad.

Q:In that chart it has 2 sections, one is maximum amps for chassis wiring and the other is maximum amps for power transmission. What is considered chassis wiring and what is considered power transmission?

Chassis wiring assumes each wire is routed separately, and power wiring assumes they are wired in a bundle. In chassis wiring the cooling of the conductors is better, because they are all exposed directly to air. In a bundle, some of the wires are not in direct contact withe the air.

Q:Has anyone ever used welding wire in their car audio setup?Is it more flexible or less than other car power wire? Is this a big problem?Is it a good or bad jacket?Would you use it again?I am looking at buying some welding wire from weldingsupply because it is .81 per foot. I would love to know if anyone has done this before and what they thought. The wire i am looking at is 4 gague.

It is actaully the exact same wire as the auto manufacturs use.... just bigger gauge is all. Edit... I see most people don't see it as possible.... well let me ask you this, How different do you think copper wire can be from another copper wire? If you really wanted too you can use speaker wire for power wire.... because at the end of the day wire is wire!

Q:Hello my question are:Examples given for wired and wireless communications systems?Compare and contrasted how wired and wireless communications systems function? Assessed the risks associated with wired and wireless communcations systems?(if you can put in simple details that would be helpful, because I understand parts of it but not all)Thank you

I additionally want under pressure out. i began out with instantaneous, however the mouse only went by hundreds of batteries, and can crap out on me while i replace into authentic interior the midst of something. Now i take advantage of a under pressure out mouse. My keyboard continues to be instantaneous nonetheless.

Q:If I have wired my 20 amp kitchen receptacles with 12/2 wire which only has a red, black, and ground wire, do I use the red wire for a neutral and the black as a hot?

You deffinatly need to put white tape on that red wire and to make it known as being a neutral.... The black wire is always going to be a hot in receptacle circuits...

Q:My starter I replaced has 3 wires, two red and one black. Where does each wire go? Pictures would be very helpful if possible

based upon the gauge you have... i do no longer think of you're placing it to a mustang yet i detect genuine low-priced air stress gauges are very deceptive.. your 5.0 may well be 50 psi (if it relatively is prolonged each and every of how out) and is a great way overinflated. the properly suited tire stress is the two interior the glove container on a plaque interior the door or is a sitcker on the rear door section.. yet stress could desire to be form of 32 psi (220 kps for our metric friends) on your motor vehicle in case you haven't any longer pushed it for greater effective than 8 hours...

Q:just bought a brinks indoor motion sensor switch and having problems installing. the regular light switch has 2 black wires that was connected to one end and a red to the other. the white wires in the wall are already together. the motion sensor switch has black, blue, red wires and its ground wire. the instructions says not to use the red wire for single switch so confused on how to wire them.

I would ignore the current setup and do what Brinks says. You can try using the wiring and capping the wires not used, test and if it works, perfect!

Q:Car audio wiring diagram

If you cannot get a wiring diagram for your stereo or car. It's still pretty simple to install a stereo. You basically just gotta color code all the wires. Red sometimes orange is power wire, black is ground, blue is remote the rest are speaker wires. Look for wires that are identical such as light blue light blue with a white stripe, gray dark gray with a white stripe etc.....
