A C Unit Switches Wire Nuts In Attic

I have an attic above but there is blown insulation and i canât see where the wires are.

A c unit switches wire nuts in attic.

Truthfully iâm nervous about the attic â the only light is b. Attic hvac systems save space. Do not switch the main power off while the unit is currently running the compressor. Wire connectors are ul listed fasteners used to make a tight low impedance connection between two or more electrical wires in an electrical box.

Well mainly it s a way to save space. Wiring an a c unit involves installing a double pole 240 volt circuit breaker in the main service panel running a 240 volt cable to the a c s location installing a safety disconnect switch there and then running weatherproof flex from the switch to the a c s terminal box. Use wire nuts to connect the black wire from the 12 2 wire to the black or red wire in the attic fan the white wire to the white wire in the attic fan and the two ground wires. A c units outside are often connected to a dedicated circuit on the home s electrical system.

I want to change the 14 2 wire running to my master bedroom light switch to 14 3 wire so i can have separate switches for the light and ceiling fan. If the term open wiring splice sounds greek to you then in simple terms a splice is a connection that is made between two wires. Open wire splices found in your home attic during the inspection could add a further dent to your bank accounts. 9 install the fans.

Locate the circuit labeled a c unit or air conditioner and make sure it is on the on position. If you can pull thermostat off wall and take a small wire and go between r and w on terminal board. So why put an hvac system up in the attic at all. Strip 1 2 inch of insulation from each end of the cut terminal wire and the end of each float switch wire with a pair of wire strippers.

The display on the thermostat is blank and the breakers are all fine. I switched off the switch in the attic that controls the furnance and now it won t turn back on. Twist one end of each float switch wire to one of the exposed section of the cut r terminal wire. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.

I have two units in the attic the other has no issues.
