Perfect question for this Section

Theoretical question:
Taking away all aspects of listed equipment, Art 400, etc and looking at it from a grounding vs bonding question.
If a heater is installed on a piece of equipment and fed by a 6 ft two conductor cord, and a bonding jumper is installed outside the cord jacket but attached to the cord per 250.102(E)(2), would the heater be considered to be sufficiently grounded ??

 

[oldsparky52]

I would think it would be sufficiently bonded.

Are you describing a cord and plug connection for power but a hard wired bond?

 

[kwired]

I also agree on sufficiently bonded, as long as the bonding conductor has minimum size IAW 250.122.

 

[augie47]

The ole bonded vs grounded... no doubt it's bonded... does that mean its acceptable by Code as "grounded" ?

 

[kwired]

If whatever you bonded it to is grounded, yes.

Art 100:

Ground.
The earth


Grounded (Grounding).
Connected (connecting) to ground or to a conductive body that extends the ground connection.

In preparing my response to the person originally asking the question, I realized I was basing my answer on Code Sections that discuss raceway. In this particular situation we are using a cord. Does anyone know of a Code reference that specifically allows the equipment grounding conductor to be run outside of the jacket ?

Is there anything that forbids it? "Anything not forbidden is permitted."

300.3(B) , as I read it, does not allow it.

Yep and I will through in 250.134(B) also.

If it's an ungrounded receptacle, could 250.130(C) apply?

Exception No. 1 ?

The only receptacles I know of that can fed from a cord are pendants.

I was assuming the 6 ft two-conductor cord went to a receptacle. Can the OP clarify this?

Depends if he has waken up from his afternoon nap.

If I may ask... why not just replace the 2 conductor cord with a 3 conductor cord? It's 6'... how much time or money are we talking about here?
