Warning Notices - BS 7671: 514-10

[Sanman1966UK]

The old problem I think - Your socket outlets are two close together and of opposite phases.

I am of the opinion that the above BS clause is applicable and only for where maintenance is being carried out. However I do agree that we all have a duty to minmise any danger and to this end I have ensured that a 1 phase to 1 desk philosophy is mainatained.

The checking consultant (CC) is of the opinion that whilst outstretched and holding a screwdriver he will be able to touch an adjacent socket with his big toe (exageration).

Are there any rules of thumb for when a ajacent outlet places a risk on a person working on an open outlet with live parts?

So, even if the CC is correct, what is the correct method of dealing with this issue? would placing a warning notice in the rear of the socket, which is ajacent an opposite phase, thus having to remove a socket outlet with a warning notice prior to accessing the second adjacent enclosure/outlet be sufficent?

Suggestion: NFPA 70-2002 National Electrical Code requires a clearance of 3 feet to have a safe working clearance in Table 110-16(a) Working Clearances. Visit

The BS Reg is clear that if a voltage greater than 250V exists in seperate enclosures or equipment which can be reached simultaneuosly by a person then a warning sign needs to be fixed to that equipment before access is gained to the live parts.

I have always used the rule of thumb as being a greater distance than the average outstreched arms as OK. However, even in that event a warning sign and belt and braces approach is always the safe option whether a requirement or not. There is no specified minimum distance I believe quoted in the Regs.
