If the load grows later, choose more margin.<\/p>\n<p>Do not size only by the device name. Check the datasheet, cable length, voltage drop, and whether the load has surge current.

A long thin wire can make the load receive less than 12V even when the supply output is correct. Measure voltage at the load end under real operation, especially for LED strips and CCTV runs.<\/p>\n<p>Use suitable wire size, branch protection, and clear polarity marking. If several loads share one supply, divide them into sensible branches so a single wiring fault is easier to isolate. Keep AC input wiring separated from the DC output side inside the enclosure.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Manage_heat_and_mounting\"><\/span>Manage heat and mounting<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The 60W rating depends on installation conditions. Enclosed supplies need airflow around ventilation openings, and open terminal areas need protection from accidental contact. Do not bury the supply under cable bundles or mount it next to a hot driver without checking derating.<\/p>\n<p>If the installation is inside a sealed box, estimate temperature rise and test a sample.
