Lee,

Since you said that you don't see any danger in this installation, do you believe that this installation violates the _wording_ of the code, or do you feel that it violates the _intent_ of the code?

IMHO if this install is done with multiple 'switch loops', then it is safe.

Does anyone see an electrical safety issue with this sort of installation?

Let me propose a different installation for consideration: start with a standard install of the exhaust fan with a _single_ switch. Now run two conductors from the first switch to a second switch, and wire the second switch in parallel with the first switch. If _both_ switches are on, then you have a parallel circuit pathway. However one of the circuit pathways is through the first _switch_, and the second pathway is through _wires_ and the second switch. In other words, with this arrangement you don't have parallel circuit pathways in _wires_.

IMHO this proposed installation is electrically the equivalent of having multiple switch loops feeding the fan. However there is now a code distinction: the 'parallel circuit pathways' are through devices (switches) rather than through the wires. Article 404 does not have any restrictions on paralleled switches [Linked Image] So if you belive that this installation violates 310.4 on a technical violation of the wording, but is not actually dangerous, that I've provided an electrically similar installation that falls under different code rules. *grin*
