It takes that long to get to the freaking heart of videos ...i swear...

[@THECompressorGuru]

thank you for not really swearing:)

[@chrismedia234]

you guys helped me a lot. Thank you appreciate it.

I am replacing a Square D pressure switch with another SD pressure switch, they look the same but the wiring if different. So, sometimes it's best to do both, take a picture and read the wiring diagram!

[@markcagle2158]

Do you know where I could get a wiring diagram for a Saylor Beall model 9000 ? I got this compressor from a surplus company and whoever disconnected the starter really did a butcher job on the box. There is a small transformer I believe was connected to the pressure switch. No sure how it is supposed to be connected. Please help !

Awesome video! I’m trying to wire a Ingersoll Rand t30 3 phase in my home garage using a VFD I have it running but can’t work out how to include the pressure switch. Do you guys have any experience with that or any suggestions would be great 👍

[@THECompressorGuru]

Erick sure does. you can contact me through thecompressorguru.com Erick will not be in until next Wednesday.

That 3 phase system has no neutral. The two phase wires connected to the coil are both "hot" wires. And it is important for the coil to be the proper voltage. A coil with a neutral involved will be a 120V coil. This system will have a 240 208 or 480 volt coil depending on the voltage of the system.

[@THECompressorGuru]

John this episode is about pressure switches. we do have an episode on magnetic starters. The coil in a starter does need the correct voltage . but this is about the switch.

[@timbaland5083]

John is 100% correct. In your diagram your pulling a neutral off L1 of a 3 phase circuit which is not correct.

[@gkindustrialmachine1]

You know ... I thought I was crazy for a second ... him calling that a neutral. That's why I came into the comment section to see if I was missing something.... I have learned nothing from this video except to get further confused. I have a 3 ph system with a starter and needed to learn...not here.

[@markcagle2158]

I have a Saylor Beall model 9000 with a 15 hp motor. There is a small transformer in the starter box I assume was connected to the pressure switch making that circuit low voltage. Do you know where I can get a wiring diagram for this unit ?

[@THECompressorGuru]

I will get Erick to respond to this but he is out of state at a funeral. it may help if you email me through thecompresorguru.com either by email or through the phone number on the website.It is possible that this may not be a factory set up it may have been done to make the machine work for a certain voltage . in any event my engineer is away till at least Friday

I have a Davilbiss 230v 3hp trailboss DAC503 AIR COMPRESSER HOW CAN I INSTALL SQUARE D PRESSURE SWITCH ON IT

[@THECompressorGuru]

not familiar with the machine you have. it is important to make sure the new switch has the same electrical and pressure rating as the old switch. perhaps I can help more contact me through thecompressorguru.com

[@Emeliotube]

Should air pressure switch be wired through contactor?

[@THECompressorGuru]

yes or no that depend on where you want to run conduit or wire. the Pressure switch DOES control the contactor. any questions fell free to contact me through thecompressorguru.com

[@Emeliotube]

Thank you

[@rogeratg9324]

What I learned is move the video half way because the rest is trash

[@THECompressorGuru]

thank you for your polite comment.
