How do you read numbers on electrical wires?
The thicker a wire, the lower its number; for instance 12-gauge wire is thicker than 14-gauge. Cable refers to two or more wires encased in a protective sheathing. Cable packaging indicates the gauge and number of wires. For example “12/2 WG” means two (black and white) 12-gauge wires plus a ground wire.
Should I use 12 or 14-gauge wire?
If you’re wiring a circuit on which there are both lights and outlets, or you just aren’t sure which wire gauge to use, you can’t go wrong by choosing a 12-gauge wire. It’s not quite as flexible as a 14-gauge wire, and it costs a bit more, but it’s always a safe choice on a 15- or 20-amp circuit.
What size wire do I need for a 200 amp service?
Installation of 200 amp electrical service needs a #2/0 AWG copper wire or #4/0 AWG for aluminum or copper-clad wire inside a 3″ conduit. Wiring a 200 amp electrical service is not a DIY job. It often requires a permit and professional installation by a qualified electrician following local electrical codes.
What size wire do I need for a 200 amp underground service?
A 200 amp service, that is being installed underground, should follow all codes and should have the correct permit for doing the work. For a 200 amp service, you will need to use a 2/0 AWG for copper conductors, or a 4/0 AWG for Aluminum or Copper-Clad Aluminum.
Can you run a 14 gauge wire off a 12-gauge wire?
More specifically, can you connect 14-gauge wire to 12-gauge wire? While this is possible, it is not recommended in order to prevent overloading. For example, if the amp capacity of your breaker is 20 amps, you should only use 12-gauge wire, and if it’s 15 amps, the entire circuit should be 14-gauge.
Is it OK to mix 12 and 14 gauge wire?
It’s perfectly safe to use it. Don’t worry about confusing future workers. If they want to add something to the circuit, they will have to go turn off the circuit breaker first, and then they will see they are working with a 15 amp circuit.
What are the general rules of wiring?
General Rules For Wiring
- Every installation is to be properly protected near the point of entry of supply cables by a two-pole linked main switch and a fuse unit.
- The conductor used is to be of such a size that it may carry load current safely.
- The conductors installed are to be safe in all respects.

What is the part number on a Volvo 740?
It is black, usually on the passenger side by the anti-freeze expansion tank. The part number is 1323592-1. My 740 had poor acceleration and hard cold weather starting here in Minnesota. The problem did not change with a replacement engine out of a 1993 940 (non-turbo).
