The answer to 'my electrical inspection won't turn on' is that there could be several common causes, such as a tripped circuit breaker, a faulty electrical component, or an issue with the power supply. The symptoms may include no power to the electrical inspection, or the device not turning on at all.
To troubleshoot, first check the circuit breaker and reset it if necessary. If that doesn't work, you may need to inspect the wiring and connections to ensure they are secure and not damaged. If you're not comfortable working with electrical systems, it's best to call a licensed electrician to diagnose and repair the issue.
