Recently finished upgrading to a 200A panel and replacing all the

First, can I putty or caulk around the wires inside the conduit to
stop the cold air from coming in?

Second, my electric bill is up about 15% since I started. *The only

replaced one 100watt table lamp, these run 16 hours a day. *Also three

What type conduit did you use on your panel feeder run ?

EMT ? *RMC ?

I am not aware of any air tight fittings for EMT, however
RMC has several different types of explosion proof fittings
and junction boxes which are used with threaded RMC
conduit... *These are the same type of fittings you see
all lined up in a row on the side wall of a gas station to
feed power and comm to the pump islands... *Such
fittings are used with an approved packing fiber and
sealing compound to create a barrier to prevent
gases, vapors or flames from using the conduit to
migrate in an electrical system...

As to your increase in the electric bill: *What did
you upgrade to 200amps from ?

You replaced some lighting, namely one 100w
lamp with six 75w lamps... *You realize that the
six lamps use 4.5 times as much wattage as
the single 100w lamp did...

You are comparing 100w per hour x 16 hours
which is 1,600w or 1.6 kWh *to
(6) x 75w = 450w x 16 hours which is
7,200w or 7.2 kWh

Without knowing more about your electrical
usage history and how many kWh your home
uses besides the one change you described
which happened at the same time as your
200amp service upgrade a definitive answer
can not be given, but it sounds like the
increase can be reasonably explained by
the lighting changes you have made rather
than a faulty electrical meter or an "estimated"
bill because your meter is only actually read
periodically as someone else proposed...

So if I have the math right:

7.2 - 1.6 = 5.6 additional KWH per day
5.6 x 30 = 168 KWH per month
168 x 0.1227 = $20.61 per month

Wow!
