Bonding in a dryer

[shaw0486]

i just purchased a new dryer, from the factory it has a bonding jumper that jumps the ground and neutral terminals out. Why is this in place and should it stay?

For a 3 wire system leave it.

For a 4 wire system remove it.

why do you say keep it for one but remove it for the other?

In a 4 wire connection the metal of the dryer is to be bonded to the grounding conductor, but not connected to the grounded conductor.

In a 3 wire connection the grounded conductor provides the grounding so the bond at the dryer has to be made.
