You wouldnt have two ident T Pulls Mark, one would be for extinguishants & there would be a secondary button (NOT T Pull) for circuit isolation.
Anyway, looking through 2010's MSA generic safety regs:
External Circuit Breaker
75.
When operated, the circuit breaker must isolate all
electrical circuits with the exception of those that
operate fire extinguishers. The circuit breaker triggering
system on saloons should be located at the lower part
of the windscreen mounting, preferably on the Driver’s
side or below the rear window. On Open Cars it should
be located on the lower main hoop of the Roll-over Bar
on the Driver’s side, or at the lower part of the
windscreen mounting (as above).
76.
On cars of periods A to F, the mounting point may
also be mounted approximately vertically below the line
of the scuttle on the Driver’s side. The location must be
identified by a red spark on a white-edged blue triangle
(12cm base), and the ‘On’ and ‘Off’ positions clearly
marked.
