In AS/NZS 3000 (2000) 4.3.11 Cooking appliances section 1 "Functional Switch" has a note 4 that says "This requirement is not intended to apply to enclosed cooking appliances such as wall ovens, microwave ovens and grills."
In AS/NZS 3000:2007 the corresponding info is now section 4.7.1. Note 4 has been reduced: The sentence is the same except that 'grills" has been removed.
My question: is a hob - such as a 4 element ceramic smooth top - an enclosed cooking appliance?
Initially I was interpreting 'enclosed' as meaning built-in - unlike a free standing range. However the intent may be that 'enclosed' refers to a cooking appliance with a door to conceal the element. But then why mention a microwave?
Thank you.
Is a Hob (Cooking Appliance) "enclosed"?

Why "2000" edition?
this clause was never mandatory.
The wording "open cooking surface" was added in A3, (2003), including examples of what is intended to be covered, as well as the not explaining examples not included.
"open cooking surface" refers to the user's access to the hot bits.
It's not about electrical risk; it's about managing a fire; so that the energy source can be removed without need to reach over / through the flames
Ovens, microwaves etc the cooking happens within the enclosed space.
hobs & deep fryers, etc the cooking is not fully enclosed, but "open"
