4 Best Practices When Fabricating a Control Panel

Use a Larger Enclosure Whenever Possible

This allows room in the panel design to properly space all of the hardware and to install larger wire ducting. Panels that have ample space tend be me more organized, while panels that have everything crammed into a small space tend to be more difficult to work in and are often less organized.

Tap Holes Instead of Using Self-Tapping Screws

It is common for panel builders to use self-tapping screws to save time during the fabrication process. While it can save time, this type of fastener does not always provide the consistent, strong connection that may be needed for the mounted hardware. This is especially true when hardware may need to be removed at some point and then later reattached. Holes that have been tapped prior to hardware installation will offer a stronger, more consistent connection point that will last longer.

Ensure that Wire Ducting is Large Enough

It is very easy to undersize wire ducting when designing a panel. It is important to always plan for wire ducting to have extra room available once all wires have been run through it, including field wires.

When in Doubt, Label it

It is a very good practice to label wires in a control panel, but it is not always required to label the other types of hardware in the panel to meet code. It is important to understand that any operators that may access this panel at a later date may not understand what the hardware in the panel is intended for. To make the panel is as safe as possible, and to allow operators to function in the panel more efficiently, it is a good idea to label everything that may come into question.
