Just as electrified cars — whether hybrids or pure battery-powered models — seem headed for market dominance, Mazda announced a breakthrough in gasoline engines that could make them far more efficient. It is the latest plot twist in a century of improvements for internal combustion engines, a power source pronounced dead many times that has persisted nevertheless. Here is some truth-squadding on the latest in auto technology.

Contrast that to an external combustion engine, where fuel is burned outside the engine and the energy created from that burning is what powers it. Steam engines are the best example of this. Coal is burned outside of the engine, which heats water to produce steam, which then powers the engine.

Most states have a 100 amp minimum requirement. Homes running under that service could consider an upgrade to bring them to between 100 and 200 amps, which could run upwards of $2,000. Homeowners should evaluate their power demands first. “A homeowner can have an electrician test the system with an amp meter while all the big loads are on,” says Holt. “If the draw is over 75-80 percent of the service size, you might consider an upgrade. Otherwise you should be fine.”

The first stage, which coincides in time with general construction work, includes the installation of fasteners or inserts in structural elements for the subsequent attachment of electrical equipment and structures for the installation of electric wiring. It also includes the installation of conduits for electric wiring in the foundations and floors of buildings or structures and the installation of wall sockets for outlets and switches. In the first stage, the preassembly of electrical equipment and wiring structures, the fabrication of conduit sections, and the board lacing of wires and cables for lighting and other circuits are carried out away from the construction site in specially equipped electrical-installation prefabrication shops.

GFCIs are also available as circuit breakers installed in the panel, giving ground fault protection to designated circuits in the home.

In the second stage, the electrical equipment and the structures for the installation of wiring are transported to the construction site, installed in the planned locations, and assembled. In addition, cables and wires are laid and are connected to the installed electrical equipment. Electrical installation work is completed when the installed equipment is actuated and adjusted. The most complicated work in this respect is the adjustment of relay protection and automatic control systems for electric drives.

It is critical in any wiring project that you match the gauge of the wire with the amperage rating of the circuit. Failing to do so can lead to a fire. A wire's gauge is the physical size of the wire, but the scale is opposite of the wire's circumference. This means that a 2-gauge wire is actually larger than a 14-gauge wire. The size determines how much current can pass through, so the larger wires will be used for your heavier loads.

Standard plastic electrical boxes do not have knockouts and contain internal cable clamps. Metal boxes may have internal clamps; if yours does not, install a locknut-type clamp for each cable. Insert the threaded end of the clamp through a knockout hole and secure the clamp inside the box with the nut. Tighten the nut with pliers.
