Question:
Hello CQD,
What is the minimum working space required for a control panel of a 480-volt electric heater? The control panel contains a contactor, control transformer, disconnecting means, and fuses. There are other electronics in this panel too.
Thanks for any info you can provide.

Hello Carl,
Thanks for participating. The minimum depth of working space required in front of the heater control panel is 36 inches based on Section 110.26(A) and Table 110.26(A)(1).
