Some of the most basic principles of good control panel design include choosing the right type and size of wiring and the layout. When you route and connect wires properly, you have a more efficient system which lasts longer and gives you fewer problems over the years. Here are some helpful tips that some automation control panel manufacturers recommend.

Wire

When wiring inside panels, it’s always best to use stranded conductors. They are softer and more flexible than solid conductors and easier to work with. Machine tool wire (MTW) rated at 600 volts with insulation that can withstand 90 degrees Centigrade, works best. If you must use any other kind of wiring, you should make notations in the wiring diagrams and design papers.

Device Spacing

Spacing is an important consideration because if you place devices too closely, it can lead to heat build up. Even though some people use a two-inch minimum spacing rule for circuits rated at 120 volts AC or less, quality conscious automation control panel manufacturers recommend three inches for greater safety and four inches on 480-volt circuits.

Ties

Using wire or zip ties to keep cables together is not a good idea. In fact, ties should only see use in temporary situations. It’s best to plan and route circuits so you don’t need any ties because when a technician works on a panel, he may remove the ties and does not replace them.

Routing Your Wires

Design your panel, so wiring runs vertically or horizontally. If wire runs diagonally, it can cause problems. It’s important to use service loops when possible, and work or train wire bends before using them. Don’t try to force them to bend once installed in the panel. When you have questions about proper technique or materials always consult with trusted automation control panel manufacturers. They have the solutions to problems.
