What Wire To Use For 30 Amp Air Condition

15 amps, 125 volts. Polarized two-slot receptacle is common in homes built before i960 Slots are different sizes to accept polarized plugs

15 amps, 125 volts. Three-slot grounded receptacle has two different size slots and a U-shaped hole for grounding. It is required in all new wiring installations.

20 amps, 125 volts. This three-slot grounded receptacle features a special T-shaped slot. It is installed for use with large appliances or portable tools that require 20 amps of current

Amp Air Condition Wiring

15 amps, 250 volts. This receptacle is used primarily for window air conditioners It is available as a single unit or as half of a duplex receptacle with the other half wired for 125 volts.

30 amps, 125/250 volts. This receptacle is used for clothes dryers It provides high-voltage current for heating coils and 125-volt current to run lights and timers

50 amps, 125/250 volts. This receptacle is used for ranges The high-voltage current powers heating coils, and the 125-volt current runs clocks and lights

Older Receptacles

Older receptacles may look different from more modern types, but most will stay in good working order. Follow these simple guidelines for evaluating or replacing older receptacles:

• Never replace an older receptacle with one of a different voltage or higher amperage rating.

• Any two-slot, unpolarized receptacle should be replaced with a two- or three-slot polarized receptacle.

• If no means of grounding is available at the receptacle box, install a GFCI (pages 74 to 77).

• If in doubt, seek the advice of a qualified electrician.

Never alter the prongs of a plug to fit an older receptacle. Altering the prongs may remove the grounding or polarizing features of the plug

Unpolarized receptacles have slots that are the same length Modern plug types may not fit these receptacles. Never modify the prongs of a polarized plug to fit the slots of an unpolarized receptacle

Surface-mounted receptacles were popular in the 1940s and 1950s for their ease of installation Wiring often ran in the back of hollowed-out base moldings Surface-mounted receptacles are usually ungrounded

Amp Plugs And Receptacles

Ceramic duplex receptacles were manufactured in the 1930s. They are polarized but ungrounded, and they can be wired for either 125 volts or 250 volts.

Ceramic duplex receptacle has a unique hourglass shape The receptacle shown above is rated for 250 volts but only 5 amps, and wojld not be allowed by today's electrical codes.

Twist-lock receptacles are designed to be used with plugs that are inserted and rotated A small tab on the end of one of the prongs prevents the plug from being pulled from the receptacle.

High-voltage Receptacles

High-voltage receptacles provide current to large appliances like clothes dryers, ranges, water heaters, and air conditioners The slot configuration of a high-voltage receptacle (page 66) will not accept a plug rated for 125 volts

A high-voltage receptacle can be wired in one of two ways In a standard high-voltage receptacle voltage is brought to the receptacle with two hot wires, each carrying a maximum of 125 volts No white neutral wire is necessary but a grounding wire should be attached to the receptacle and to the metal receptacle box Conduit can also act as a ground from the metal receptacle box back to the service panel

A clothes dryer or range also may require normal current (a maximum of 125 volts) to run lights, timers and clocks If so. a white neutral wire will be attached to the receptacle The appliance itself will split the incoming current into a 125-volt circuit and a 250-volt circuit

Repair or replace a high-voltage receptacle using the techniques shown on pages 72 to 73 It is important to identify and tag all wires on the existing receptacle so that the new receptacl will be properly wired

Childproof Receptacles & Other Accessories

Childproof your receptacles or adapt them for special uses by adding receptacle accessories Before installing an accessory, be sure to read the manufacturer's instructions

Homeowners with small children should add inexpensive caps or covers to guard against accidental electric shocks

Plastic caps do not conduct electricity and are virtually impossible for small children to remove A receptacle cover attaches directly to the receptacle and fits over plugs, preventing the cords from being removed

Recessed wall receptacle permits a plug-in clock to be hung flush against a wall surface

Install more than two plugs in a single duplex receptacle by using a multi-outlet power strip A multi-outlet strip should have a built-in circuit breaker or fuse to protect against overloads

Protect electronic equipment, such as a home computer or stereo, with a surge protector The surge protector prevents any damage to sensitive wiring or circuitry caused by sudden drops or surges in power
