The answer to 'lighting installation burning smell' is that a burning smell from a new lighting installation is often caused by faulty wiring or a malfunctioning light fixture. This can be a serious fire hazard, so it's important to address the issue promptly. Common causes include improper installation, overloaded circuits, damaged or exposed wiring, and defective light fixtures.
If you notice a burning smell, immediately turn off the power to the affected circuit and inspect the installation. Look for signs of scorching, melting, or other damage. If you can safely identify and fix the issue, such as tightening connections or replacing a faulty component, you may be able to resolve the problem yourself. However, if the issue persists or you're unsure of the cause, it's best to call a licensed electrician to diagnose and repair the problem to ensure your safety.
