120/240 to 120/240 transformer?

[gjjdemarco]

Hey everyone, I am new to the forum and appreciate your help.
Here is the situation I have:
I need to provide power for a camera system.
System installer says they require 120v with a neutral and a ground.
Camera is being installed on a street light pole where I have 2 legs of 120v to ground, but no neutral available.
I cannot get back to source panel to bring a neutral out.
I don't do much of this, but is there a transformer available that does 120/240v to 120/240v that I could mount at/near the light pole to create a new 'system' with a neutral?
Thanks in advance for your help,
GD

You state you have 120 VAC to ground on two legs so you have 240 single phase and yes there are transformers that are 240-240/120.

Depending on the size one of these links should help.

Also check if the camera enclosure has a built in heater, that will add to your load calcs.

You just need a straight 240->120 transformer.

It needs to be an isolation type, not an auto-transformer since you require a neutral. The neutral on secondary becomes the neutral once you ground it.

Not a neutral but rather a grounded conductor, often called a neutral by the ignorant. The system has to have a neutral point before the connected conductor can be called a neutral.
