Q:can aluminum wiring catch on fire

You got lots of good answers but I like Lic. Electricians best. If you are in an older Mobile home where all the wiring is aluminum be very, very careful about over loading receptacles. Aluminium wire was outlawed for use in branch circuits (receptacles, lights) because there were many documented fires as a result of its use. If you are concerned about aluminum wire to the panel or major appliances, have someone check/tighten the connections.

Q:When I am wiring my sub to my amp, what gauge of wire should I use? The sub is 750 rms and the amp is 700 rms. And how do I wire a 2 ohm sub DVC to a 2 ohm stable amp?

the present passing for the duration of the wires will reason the wires to warmth up if no longer sufficient guage. think of of the hundreds of thousands of little electrons pushing and shoving returned and forth, all this action motives friction on a molecular point and of direction all of us understand friction equals warmth. In a bigger guage twine there is extra area for the comparable form of electons. it truly is truly that straightforward. Use as heavy a guage speaker twine which you would be able to. you will have no sign loss and little warmth.

Q:Broken dryer, 4 bladed wire, Old dryer available to me, has a 3 wire cord, can I swap the cords?

the guidelines basically recently replaced interior the previous couple of years requiring new properties to be geared up with the 4 prong recepticals rather than the three prong recepticals for 220 V merchants. in the experience that your dryer is fantastically new, interior the final 4 years or so... the twine that is hooked as much because it now could have the skill to be interchanged with a 4 prong twine by basically buyingh a 4 prong twine and screwing the eylets to the surprising connections at the back of your dryer. in the experience that your twine won't be able to be switched out, then i'd pass backward and replace the 4 prong container with a three prong container. i'd do it this sort so as that one and all your electric connections are interior a receptical, rather of having 220 Volt wires basically twine nuted at the same time.ok good success.

Q:What is the best brand of wire to use for getting power to my amp?

Monster cable 10 awg

Q:A wire has resistance 56.8 ohms. If another wire consists of the same material but has twice the length and half the diameter of the first, what is the resistance of the 2nd wire?

The two wires are composed of the same material, so we can concern ourselves solely with their respective dimensions. The second wire has half the diameter of the first, which means a cross section of the second wire has only 1/4th the cross-sectional area of the first wire (the area of a circle being proportional to the square of the diameter). The second wire is also twice as long as the first wire. Since electrical resistance is inversely proportional to the cross-sectional area of the wire and directly proportional to the length of the wire, we must have the resistance of the second wire to be 1/(1/4)*2*56.8 = 4*2*56.8 = 8*56.8 = 454.4 ohms

Q:Is there special speaker wire in order to run 250 watts max rms or will the oem speaker wire in the car be sufficient (did not originally have an amp and is most likely at 50 watts max rms). If I need a special wire for that please let me know what it is called and possibly an example link. Thanks!

most likely the wire pre ran in the car was 16 guage wire which is fairly small id recomend atleast 12G for speakers and 8G for a power wire.

Q:i am re-wiring light switches in my home. Pulled off the old switches and there are four wires. 1 red, 1 black, 1 white and 1 bare. My light switch has three spots, 2 brass screw plates and a ground screw, what of the 4th wire?

Seems like you have three way light switches. Try using a three way light switch there is a difference from a regular light switch.

Q:installing whelen car strobe lights.the directions say to wire the power to the battery with wire that can hold 125% of the power

even speaker wire can handle 12V of power direct to the battery as long as there is some sort of fuse in the setup and you are properly grounded

Q:The wires I have are: 1 red starter cable, 1 tan wire, 1 ground wire to the engine block, 1 red wire to the battery, and 1 red wire that splits into the fuse and into the junction strip. Really need to know which wires go where on the solenoid.

Jtex has the right answer if you bought the right solenoid. Unfortunately- the Ford automotive solenoid is an exact replica, but wired different. So less you got the part from Mercury -your going to burn wires as the Ford puts power to one of the small terminals and the Mercury wants a ground to the same terminal as it's ground is regulated by the neutral no start switch.

Q:I have a wire coming from the car battery positive terminal. It is 12v DC. I want to split this wire to two other wires. I cannot connect another wire to the positive terminal. Will splitting this wire cause the voltage to drop to 6v each wire? or will they pull a constant 12v each?

Splitting would not reduce the voltage, but you have to check the load and make sure that wires are adequate to handle the currents involved.
