What I have pieced together from comments on the show is that the top,
with the hot service wires, has to remain enclosed when the trim is off
and that other wires can not go through that area. If the panel is
vertical the wires come in the lower sides. If the panel is horizontal
the wires travel a shorter distance to get to the same area.
It seems rather odd to have the panels horizontal since it is not
allowed in the US. Breakers must be off in the down position.
I have not understood why they replaced some panels. Or why some other
work was done. Given some of the major disasters Holmes finds I
sometimes wonder if quality of construction can be much lower in Canada.
Some interesting shows though.

I don't know of any US panels that have that. Seems like it would not be
that hard to substantially guard just the service lugs with plastic.
There are 'touch safe' terminal bars for control wiring now.
You probably could build one but it is not likely practical. The spaces
would be cramped. Limited KOs in the top. Service wires may come in the
You also wind up with more wires in the top gutter space. I wonder if
Canada has the same limits as the US for gutter wire fill.

Panels HAVE been made that way - but MOST panels that I've seen where
branch circuits enter the top of the panel either have the main at the
bottom (with power entering from below or through the back of the
panel) or on the side. Running branch circuits through the power
supply side (main) of the breaker is NOT allowed here in Canada - and
is not a good idea under any circumstances.
The MAIN breaker must be up for on if vertically operated here, and
is generally Left for on and Right for off on a horizontally activated
main breaker or switch.
Physically IMPOSSIBLE on a 120/240 panel with a shared neutral, which
is almost universal in Noth American residential wiring. Half would be
on up, and half on down
You will note MOST of those horizontal installs are surface mounted on
the framed wall of a basement, above the concrete foundation (and
above outside grade) There is a limit in Canadian code to how high or
how low you are allowed to mount the panel, and "side mounting" keeps
all of the breakers at virtually the same height from the floor as

Actually.. if you watch enough of the shows he has fixed American homes as

That's not _quite_ what US NEC actually says...
P 240.33 Vertical Position
Enclosures containing overcurrent protection devices shall be mounted in
a vertical position unless this is impracticable. Circuit breaker
enclosures can be installed horizontally, if the circuit breakers are
installed in accordance with 240.81. Figure 240-28
Section 240.81 specifies that where circuit breaker handles are operated
vertically, the "up" position of the handle shall be in the "on" position.
So, the prohibition isn't that the breaker must be operated vertically,
but that if it is, it can't be upside down (off pointing up iow). If
that weren't the case, the cheapie's w/o a main but using one slot as
the feed in the panelboard wouldn't be allowed as they're horizontal.
I've not read the Canadian version but seems rather bizarre to me,
too...but if hadn't seen anything but, then would probably seem normal.
It does seem peculiar when clearly the panels themselves are
manufactured with the idea they'll be vertically-mounted simply by the
orientation of the printing and all.
If the Canadian version is different in preferring horizontal as
outlined in the above conjecture, it would likely be because some
particular person some time in the past had a fixation on a perceived
"better way" and prevailed in getting it into their Code.
Unless you are surface mounting a breaker panel, vertical usually works
better anyway because the panel will fit between two studs. Mounting it
horizontally would require a header across the wider opening (unless it's a
small subpanel or something).
On all of the panels I have installed, the breakers mount sideways.
Even if I were to mount the panel horizontally, the breakers on one side
would flip "up" to turn on, and the other side would flip "down" to turn
on. If I remember correctly, "on" is always towards the center of the
panel, regardless of orientation.

Law in Canada requires the panel to me mounted on a "panel board" -
basically a piece of plywood of a minimum size, which all incoming
wires must be attached to, and the panel must be attached to. Code
dictates how the panel board must be attached to the structure.
General procedure in semi-finished areas is to bring the wires down
inside the stud bay, and out through holes drilled in the panel board,
then straight down into the panel, stapled to the panel board within 6
inches. The wall can then be dry-walled or plastered or whatever to
"finish" the wall.
Also, many of the installations were origionally fuse panels, which
had no restriction on orientation and were often wider than today's
breaker panels, and the only practical way to replace them with a
breaker panel is in the horizontal orientation - which is allowed for
in US code by the "vertical position unless this is impracticable"
Horizontal mounting of service panels is a "practical" consideration.
Inn Canada, MOST houses have basements. Historically most houses had
the panel in the basement. Those that do not have basements, or where
the panel is not in the basement, the wiring comes down to the panel,
lust like in the basement. The neatest, simplest, installation is to
drop the wires directly into the panel rather than running the wires
down beside the panel, making a right angle, and entering from the
side. Since it is illegal to run protected circuits down through the
main disconnect (unprotected) part of the panel, the simplest solution
is to horizontally mount the panel, with the wires entering what is
now the top of the panel, directly. With the large number of circuits
in today's houses bringing all the wires down the side in right
angling in makes for a real mess of wiring.
Totay's breakers are all well marked as to on or off, confusion as to
whether the breaker is on or off should be extremely rare!!
The main must be on to the right or up, so the panel cannot be mounted
with the main disconnect on the right - and you will ALWAYS see Holmes
horizontal installations with the main disconnect on the left.

Yep, when I bought this house it only had a 60 Amp service in Toronto,

The system will be down for 10 days for preventive maintenance.

That's interesting. Not sure I've paid close attention to new
US panels. Do they have the service wires in a separate section
now too? All the panels I've seen here there has been no separation.
But even if there is required separation, I don't see why that would
block off the whole top of the panel. I would think it would just block
off the center third or so where the service comes in and the main
breaker is located.
With the large number of circuits
I agree. But here in the US they are vertically mounted and the
wires come in at the top (mostly). At least in panels as of about
7 years or so ago, which is the latest vintage I've been involved with.
