12v socket in the rear

[Simon37]

The 12v socket in the rear on my vehicle states 320W max next to it yet its fused with a 15A fuse. Basic school physics ( Power = Voltage x Current) tells me it cannot output 320W the power is 12V x 15A = 180 W so the max power you can draw before the fuse blows is 180W. I tried this with a device I knew drew over 200W and sure enough the 15A fuse blew. Why have they stated you can draw 320W from the socket ???

Sorry for the late reply @Simon37 . just found this post looking for info on what is behind the panel in the lhs of the cargo area with a view to relocating the 12v outlet
The 320W is initially misleading, in that while individually this socket and the front 12v socket are restricted to about 180W max each, if used together, the total draw should not exceed 320W.

Question: sorry if this has been raised previously, I've been unable to get a result from search. Can anyone enlightened me as to what purpose is served by the blue socket, behind the LHS panel in the cargo area ?

Hookup for the factory inverter option.
