[dmulhol925]

Is the door with electrical components installed on it required to be grounded? If so, what code section requires this?

Try looking over 250.110

It may not be NEC application, but rather a UL508A. But 508A requires the door to be bonded if there are powered devices on the door.

Solid State Devices may malfunction if the panel door is a few volts above ground in addition to the safety issue.

Likewise, if the installation is subject to NFPA 79 then article 8.2.3.6.1 of that standard applies:

"Where electrical devices are mounted on conductive
doors or covers, an equipment (protective) bonding jumper
shall be installed."
