I am looking to design an electrical surgical tool that will have a metal Applied Part but the attached handle, held by the surgeon, is also metal and at the same potential as the Applied Part. In normal use the handle would not necessarily touch the patient.
I know that it is acceptable, although not ideal, for the AP to be protectively earthed and Type B. However if instead it were type BF, would the handle be considered as:
i. Effectively an Applied Part (see clause 4.6) or..
ii. An accessible part (in which case definitely a no-no e.g. Mains on AP)
I would really appreciate any thoughts on this.
