What kind of diagram are you looking for? Large business and warehouses have 3 Phase. I've not heard of a house. but let me know. Typically 110 comes out of one breaker and one neutral wire (and saftey ground is 3rd) 220 comes out of two hot leads and one neutral wire (single phase). 3 phase comes out of 3 hot leads and one neutral but is still 220 volt.

dear sir
try to find out first all wire wich type of you shold use ampere meter for testing thise wire .
ampere meter turn into continuty mode and conecect its one lead (wire cable) to your motors black wire and watch the display what is rating there .and write it next wire check and date write like this way check your all 4 wire and now who is high number data its conect to number 1 after that some low conecet number to switch number 2 after that who is lowest conect to number 3 and that black colour wire conect to the L mark then try to start your motor
hope answer the question
thank you

You may have your plug wires in the wrong order.
The firing order is 1-3-4-2 om cpounter-clockwise rotation. Look at the digram below. Notice the shaded blue is cylinder 1. From there, make sure 3 is the next wire, then 4 and finally 2.

I am attaching the photos showing how the dryer cord for either a 3 or 4 prong outlet, since I don't know what type outlet you are using. Hope this helps and best wishes.

the four wire plug seperates the neutral and ground. the three wire just piggybacks the ground to the neutral. so just get a three wire cord that fits the 220 plug on the generator and install it on your dryer make sure to attach the ground correctly for your three wire setup

1.check spare parts of compressure.
2 check wireing of compressure.
3. check voltage.
4.check continuti of compressure.
5. check discharge pressure.
