You have made a circuit that works. Please be advised it is not safe and is also not to code. In the event one of your buildings burn down or worse someone gets electrocuted the liability will likely go back to you and this choice. Insurance would likely also be denied. If you go to sell your place and there is an inspection done it will likely result in stopping the sale.Well I have 120 power, lights and outlets are good. Wired one leg as hot wire, capped off other hot wire and used ground as neutral. Didn’t work at first because ground was corroded at clamp. Thanks for all the advice.
You have been given several solutions that would be safe and to code and you fail to try and understand the issues.
If all you require is 120V at your outbuildings the best solution was given early on suggesting you get rid of the 240v breaker replacing it with a 120v breaker and use the two wires you have to carry 120v out to your building one as a hot the other as the neutral.
I strongly suggest you read the below linked information.
