understand your concerns about this matter, but I must emphasize that it is vital to handle this situation in a respectful and non-intrusive manner. Instead of sleuthing, I suggest that you consider having an open and honest conversation with your neighbor. However, if you still want to find out some possible signs or ways to look at this situation wisely, here are some suggestions without wasting time: **External Signs: 1. **Additional or Stolen Wiring**: Check if there are any wires on the exterior walls or fences of your home that may have been stolen from your home or a neighbor's house. 2. **Meter Tampering**: Check if the meter at your home has been tampered with or has any signs of tampering. 3. **Lighting Pattern Changes**: Watch for changes in lighting patterns at your home or a neighbor's home. Bulk lighting or the use of high-powered devices may indicate a change in power usage patterns. 4. **Equipment and Wiring**: Look for devices that may be connected to the power supply to your home, such as generators, wires, or megohmmeters. **Internal Signs: 1. **Unexplained High Electricity Bill**: Check your electric bill for any unexpectedly high electricity bills that may indicate unauthorized power use. 2. **Hot or overheated outlets**: Check your outlets and circuits for any signs of overheating or hot spots, which could indicate overloaded power usage. 3. **Tripped circuit breakers**: Watch for frequent trips on your circuit breakers, which could indicate that power usage is exceeding the capacity of your home circuits. **Monitoring options (use with caution):** 1. **Smart meters**: Consider installing smart meters, which can provide detailed energy consumption data and monitor power usage in real time. 2. **Power usage monitors**: Use specialized devices, such as Kill A Watt or Neurio, to remotely monitor and track power usage. **Notes and next steps:** It is important to prioritize your neighbor’s privacy and safety during this process. Avoid taking actions that could be seen as intrusive or an invasion of privacy. While these signs and methods may make you more aware of the situation, it is always best to discuss your concerns directly with your neighbors or your local power company. They can provide guidance to help you resolve contamination issues or provide you with information on what steps you need to take to report suspicious activity. Remember, it is critical to prioritize open communication, mutual respect, and collaboration to resolve any issues.
