A/C keeps tripping from noon till dusk
Hi everyone, we live in Texas and it gets 110 out here. The Ac system keeps tripping at peak time from noon till 7 but will run perfectly at night. Can someone please give some advise on how to fix th...

Overloaded electrical source supply sure comes to mind. Simple formula is the "voltage" (line pressure) expressed in watts supplied to a 15 amp device at 120 volts being 1800 watts consumed is receiving just 100 volts of line pressure and only will receive 1500 watts at 100V, it struggles and heat builds till power cutoff or even long term motor etc burnout for an example. It wants and needs the 1800 watts!
The normal 15 amps at 120 volts now becomes 18 amps required at 100V thus due to the lower line voltage at 100V. Some refer to it as a brownout condition and worsens as line voltage continues dropping until cutoff. For example, if you were drawing 30 amps when the voltage was at 120V but it's now requiring 36 amps at 100V and something has to give and will. When the increased amperage draw exceeds the power source's fuse limit, the fused circuits trips whether at your end or at the mains and no power is received.
When do the masses of high A/C use hit the extremes in hot areas of the country? By noon and till evening of course! Easy and quick to monitor line voltage received in your adobe but not so easy to monitor voltage or amps drawn at the main source off property.
If not a voltage issue as delivered or at your A/C unit wiring line input, you likely have an A/C unit with issues or needing to be replaced.
