The codes are concerned with proper size of wire and with insulation. Factors that are considered are the expected load, the frequency of modifications, and the nature of the environment where the wire is used. Homes have small loads, infrequent modifications and a very non-corrosive environment. Commercial establishments are usually in the middle. The load demands are sometimes higher, and modifications are not infrequent. The factory or industrial site has a very high demand. Modifications are frequent, and the environment is often highly unstable.

"We first needed to understand how much heat was available from the powertrain during various drive cycles and cold start conditions," he says. By simulating thermal components that control the powertrain heat, such as the electronic thermostat, cooling fans, grill shutters, and water valve, they determined the best way to distribute the available energy.

The cable sheathing (outer jacket) should extend 1/2 to 1 inch beyond the clamp, and the cable wires should extend about 6 inches into the box. If necessary, trim the wires as needed and strip 3/4 inch of insulation from the each of each wire, using wire strippers. Secure the cables by tightening the screws on the clamps, being careful not to overtighten and damage the cables.

Inside the grooves piston rings are put in. The piston rings are the part that actually touch the walls of the cylinder. They are made from iron and come in two varieties: compression rings and oil rings. The compression rings are the top rings and they press outward on the walls of the cylinder to provide a strong seal for the combustion chamber. The oil ring is the bottom ring on a piston and it prevents oil from the crankcase from seeping into the combustion chamber. It also wipes excess oil down the cylinder walls and back into the crankcase.

Use a screwdriver and hammer to break out each knockout (metal disc), then twist off the knockout with pliers.

If the box is metal, add a pigtail—a 6-inch length of the same type of ground wire—to the ground wire connection, then connect the loose end of the pigtail to the ground screw on the box. Join the white (neutral) wires together, then join the black (hot) wires together. If there are red (hot) wires, join them together. Confirm that all wires are secure by gently tugging on each wire.

Turn off the power to the circuit you'll be working on by switching off the appropriate circuit breaker in your home's service panel (breaker box). Test all of the wires you'll be working on with a non-contact voltage tester. The test should confirm that no voltage is present in any of the wires.
