Hello anonymous,
I am concerned in so many ways... (USA
NEC assumed):
FIRST concern:
(after the obvious BATHROOM/GFCI issue) is the
NATIONAL ELECTRIC CODE for wire/device capacity
INSIDE your existing ELECTRIC box...
The
CODE requires wires to have space ... aside
from the fact that it is just plain dangerous to
pack wires densely and pack them together tightly...
Then... of course... You have said nothing about the wire gauge/ampacity... (again assuming 14 Gauge/15 Amp)... you will have to calculate the fill for each wire and check the Cubic Inches
Plus your device against the ELECTRICAL BOX rated capacity...
That is just the BASICs of SAFETY.
Looking for a diagram of your
"1595" Legrand Pass & Seymour I have failed miserably.
I have found what
YOUR switch looks like...
From an old electrician's standpoint...
If you have EACH device wire separately thru
their respective switches...
There should be
NO POWER to operate the FAN.
The
FACT that there is ... Is highly
PROBLEMATICE.
It would seem that a PREVIOUS ELECTRICIAN
has switched the
NEUTRAL side of your
old light circuit... Easy to
prove with a VOLT TESTER.
I Recommend
KLIEN NCVT (non-contact volt tester)
Klein Tools NCVT 1 Non Contact Voltage Tester Electrical Tools Amazon com
A SWITCHED NEUTRAL
poses an EXTREME hazard in a bathroom
(any water) location but is EASY to fix...
Rip it ALL apart and properly configure all the EXISTING WIRES...
Do it right... Be safe.
