Ground Stud for 40A Circuits

[FRC1114]

Greetings GDC,

<R50> states that: "All circuit breaker distribution panels must be connected directly to the power distribution block. No intermediate connections are permitted."

We would like to know if it would be legal to connect all the ground wires returning from the Victors powered by a 40A breaker together at an intermediate ground stud. We would use one wire from this stud to connect back to the Power Distribution Block. Since these wires are not a connection between a breaker panel and power distribution block, we think this would be legal.

The reason we wish to do this is because the 40A maxi style circuit breaker panel does not have a ground stud, unlike the circuit breaker panel for the 30A and 20A fuses.

Cheers,

[GDC]

As illustrated in the 2008 Robot Power Distribution Diagram, all ground returns must connect to either the Power Distribution Block or the common ground terminals on breaker panels. Note that ground returns from circuits energized via the Maxi breaker panels may be routed via common ground terminals on other breaker panels.
