If you've finished a new electrical installation, it is a great idea to bring in a licensed electrician to vet your work and ensure that all safety measures were taken. They will confirm whether the installation is safe or provide assistance to make it so. To know if your electrical systems are continually safe, it is smart to conduct yearly safety checks. Testing your outlets with a “cube” or “block” tester, visually inspecting all exposed wiring for cracks, splits, or rodent damage, or doing a voltage test to ensure consistent readings are all excellent ways to keep a safe and secure home.
