Q:from my house I am running 300 ft of buried cable. for lights out side. 30 amp breaker. what size wire should i use

You are working from the wrong direction. What is the draw of the light fixtures? When this and the voltage are known, then the wire size and line loss can be computed then the breaker size is fixed to protect the wiring and the system. The best solution is to call a qualified professional electrician to do the work. The trench for the wire needs to be at least 3 feet deep and buried properly with warning tape over it. In general a 10 ga wire can be protected by a 30 amp breaker, but the 600 foot run means a large line loss and that means a larger wire is needed.

Q:Will the 20 kilowatts with 380V power supply to use much of the copper wire?

The provisions of the provisions of the cable tray is strictly prohibited lay the upper reaches of the thermal pipe, if limited to space constraints, you can use pad insulation materials

Q:I want to upgrade from a 100amp service panel to 200 amp service panel, I am hiring an electrician, however i feel im being taken advantage of (im disabled), I would like to know how to find out what the load/rating is on the existing wires from the power hub accross the street to my electrical panel really are, the wires are underground and every bid I have gotten calls for the tar road to be cut up and entire new wires installed and I dont have that kind of money. Also since the house is NOT that old I dont think the wires need to be replaced. since some of my neighbors have upgraded w/o tearing up the road etc.

200 amp? that's something you will need in a small factory not a house

Q:i have a problem where my acc fuse keeps blowing and im tired of replacing fuses so what i was wondering is if it was safe to straight wire an interior light with an inline fuse and a toggle switch and would it cause any kinds of conflict

It will not be a problem just make sure the wire doesn't touch ground(metal) anywhere and also keep a check on it for ware. If the wire touches metal after the inline fuse it will blow it. If it grounds before the fuse then it could cause a fire. So protect it well and it should be fine.

Q:What are the meanings of the English symbols on the chart?

Dark and beautiful: easy maintenance problems when the maintenance difficult, can not easily increase the dead inserted. Trunks: easy to install, can be added at any time plug and replace the wire, but not beautiful. Each with advantages and disadvantages.

Q:I Just bought a house and in the bathroom are exposed electrical wires that should be hooked into an outlet. I just want to safely cover the wires and out them in the wall. How do i do this? I was thinking wire nuts, but are those not for connecting two wires together?

By you comment you just showed me how much you do not know therefore anything you do could electrocute you. To be gin with there are wire nuts that can not only be used to bind two wires together, three wires together and so on. suggest you talk to several friends who may of had experience in doing what you need done, have them do it for you and you watch and learn how to do it the next time around

Q:How many square wires are used for home wires? It is best to have a detailed answer

ZR: flame retardant K: control cable code VV: recording ethylene insulation and sheath R: soft structure conductor (multi-strand wire) P: copper wire braid shield 1: 1 to 2 * 1.5: two 1.5 square single Twisted pair Full name is: flame retardant type recording ethylene insulated and sheathed copper wire braided shielded flexible cable. If it is 10 pairs of 2 by 1.5 square control cable, that is 10 * 2 * 1.5. In addition, the control cable, the conductor is the largest square: 4 square.

Q:I purchased at Ace Hardware a Bell Wire, and it says on the back for low voltage use up to 48 volts it is a solid/very sturdy wire with a green instulation i have three questions;1) can/should i use it to wire 3 3v led's to a nine volt battery or is it to thick of wire?( to thick meaning the 9v wont fill the whole wire resulting in loss of electricity)2) Can/should i wire 2 12v 12amp batteries an extremely short distance with it or is it not of high enough quality(like gauge).3) is there such thing as overkill? ex: using 12 guage wire for 2v or is it just unreasunable to do thatPs. Sorry for all the confusing launguge i dont know all the correct terms, im trying my best.

Bell wire is solid copper wire that is used to hard wire door bells. It can be used for any low voltage, low power application.

Q:Hi, I am building a greenhouse in my backyard and had a few questions as to how i should wire it. The appliances I will have in the greenhouse include.A 400 watt light.a 115 volt pump, an oscillating fanand a ventilation fanI can't remember the wattage of the two fans. But my question is will I need to run more than one wire out to my greenhouse? The wire I have says its max voltage is 600. any tips and advice would be nice.

Lights and fans don't take a lot of juice - just get some 12-2 wire with ground - you can get stuff you can bury in a trench if you want. Wire this into a 20 amp breaker in your house and run it out to your green house. Come up through the ground in a piece of conduit - and hook this to a big double box - something you can screw securely inside your green house. Make sure you get all your grounds connected nice. And put in two plugins. You can also put in a GFI plugin - and wire the other plugin to it - so that if the circuit blows, it kills the other plugin. That should do it and protect you pretty well.
