Our field service group uses an ESD field service kit. This is provided with the standard ESD wrist strap & grounding cord terminated with the standard banana plug. We also provide them with a large "gator" clip which can plug into the banana plug. We have also incorporated onto our device enclosures a small metal banana jack, labeled it "ESD Grounding" and advice our service staff to connect their ESD wrist strap/cord into this jack when ever performing field service repair work (ESD related). Metal to metal contact is assured between the banana jack and the frame. The service person is advised to also assure that the device is plugged into the A/C wall outlet during service repair. (provided they are not repairing the A/C power circuit/components!) Even if the device is not connected to A/C safety ground, ESD charges will be equalized between the repair technician, parts and device under rapier thus minimizing voltage differentials. I hope this sheds a little light on your question!

We are presently using banana plug type. The views expressed are my own and not necessarily that of my employer's.
