Here's what APC has to say about it:

Sorry about the wrap...

Basically, they say not to plug surge strips into the output of a UPS.
You should use PDU's instead.

OK this is only probably marginally operational.  Yesterday we were
inspected (quite thoroughly I might add.....) by the city fire inspector
for Missoula, MT....Now we did have a couple of things I know need fixing,
an emergency light with a dead battery upstairs, I'm using a long orange
extension cord w/o a breaker on it for my monitor at my desk.  And one
incidence where we had some piggy-backing going on.

Now what I'm asking is this:  we were told that you can NOT plug in breaker
protected six outlet strips into battery backup units such as APCs, and we
were (or are) being written up for that.  My understanding is that most/all
(atleast APC units) are properly de-rated (per UFC) and you *can* plug in
additional breaker protected extension cords into these units.

The problem is if this is not the case we'll be having to put a LOT more
BBUs out into our office for workstations than what we planned.  I've also
never seen this cited as a problem but I could just be ignorant too.

Please reply off-list.  Sorry if anyone feels like this is a waste of time,
but if there is interest I will summarize on list.

If this really is true then I can see a lot of places breaking this fire
code even here locally.  I'm not sure what part of the code it is but he's
stated that if I can get him some form of documentation from teh
manufacturer or something then he can make a deviation.  With a 2200VA unit
only having 4-6 outlets on it I can't see *not* using additional power
strip off the back of it.

Thanks guys, back to the regular NANOG channel...
