I often quote the 2m rule, but as I think Ban pointed out in a previous thread, I think the 16th/17th does not actually mention distance. Yes, the OSG & BRG advise 2m, but it is not set in stone.
Just for amusement value, this is the history of the "2m" rule from the 14th onwards:
The 14th says,
A29.
Every stationary cooking appliance shall be controlled by a switch separate from the appliance and installed within 6 feet of the appliance. Where two SCA's are installed in one room, one switch may be used to control the two appliances provided that neither appliance is more than 6 feet from the switch.
The 15th says,
476-20.
Every fixed or stationary household cooking appliance shall be controlled by a switch separate from the appliance and placed within 2m of the appliance. Where two SCA's are installed in one room of household premises, one switch may be used to control both appliances provided that neither appliance is more than 2m from the switch.
The 16th says,
476-03-04
Every fixed or stationary appliance which may give rise to a hazard in normal use and is connected to the supply other than by means of a plug & socket complying with regulation 537-05-04 shall be provided with a means of interrupting the supply on load. The operation of the means of interrupting the supply on load shall be placed so as not to put the operator in danger. This means may be incorporated into the appliance or, if separate from the appliance, shall be in a readily accessible position. Where two or more appliances are installed in the same room, one interrupting means may be used to control all the appliances.
Anyone care to add what the 17th says? I have not got my copy to hand.
