I'm new to projects requiring high voltage, but I need to wire 110v to an SSR controlling a device that pulls 2 amps and all I can find in my shop is some 18/2 doorbell wire. Is this safe to use?
psparky said:Using too big of a wire never hurts, especially for a short run and small application like yours.

Psparky, I realize you were not referring to the same thing I am and agree that when it is sensible it is better to be a size larger. It is likely that in this case the OP has enough room to use #16.

psparky said:Understood. Just saying these are the min sizes in certain factories for 120 volt wiring.
Having #10 wiring for lighting would piss me off too in a residential home.
I sometimes have to run #10 wire in factory lighting and sometimes even #8 when the lights are 500 feet away from the panels to avoid voltage drop. In rare cases I've had to use #4 wiring for lighting to avoid voltage drop...but this was for outside parking lights that were over a thousand feet from the panel!

berkeman, I don't think I will need building inspectors to sign off on this project, but thanks for the advice.
Averagesupernova, my thoughts are to make a power cord that plugs into the wall, which routes to a PID and has one wire tied to the controlled device and one to the HV side of the SSR. The PID out will connect to the SSR for the signal and the controlled device connects to the HV side of the SSR.
Yes, 18/2 wire is suitable for 110v wiring as it is rated for up to 250 volts. However, it is important to make sure that the wire is properly sized for the amperage of the circuit and that all safety precautions are followed.
As long as the wire is properly sized and all safety precautions are followed, 18/2 wire is safe for 110v wiring. It is important to use wire rated for the appropriate voltage to prevent any potential hazards.
The maximum amperage for 18/2 wire is typically around 7 amps. However, this can vary depending on the specific type of wire and the environment it will be used in. It is important to consult a professional or refer to the manufacturer's specifications for the exact amperage rating.
It is not recommended to use 18/2 wire for outdoor 110v wiring. Outdoor wiring requires a higher gauge wire to handle the potential hazards of moisture and harsh weather conditions. It is important to use wire that is specifically rated for outdoor use.
The correct wire size for 110v wiring depends on the amperage of the circuit and the length of the wire run. It is important to consult a professional or refer to the National Electric Code (NEC) for the appropriate wire size. Factors such as voltage drop and the type of wire used may also affect the recommended wire size.
