First I got a permit. Was not too tough. And have a call in to PG&E

to
talk to an inspector about requirements and the like. What I need is a
step by step by someone who does this routinely. What's next?

I had conflicting bids from electricians on the upgrade. Some said -

$1200
to $1500. When they had found out the main power is coming in from the
bottom, they just laughed and said "All you need is the panel,

Cletus."
The
present panel is a single panel with the meter on the top part and the
breakers under it. Got the Spa wired to 220V on a bridged 40 amp

breaker.
The rest is small potatoes. 20A breakers running to simple outlets and

the
like. I was told by Home Depot, I need a separate breaker for the Spa,
located 6' or less from the Spa, and that the way it is in the main

box,
is
a violation. Ugh. (That'll be tough, as the Spa is on the Patio, away

from
the wall by 15' or so.)

I'm willing to buy the box for that as well though.

I need to be pointed to a step by step, or if it's not too much

trouble,
post one here. I'd like to be clear on the steps to take.

Can I surface mount the 125A box? The present one is recessed into

the
wall. The box I was looking at requires a BIG hole! I'd like to just

get
the wires in on the bottom, and cover up the present little hole with

the
big box.


If the people at Home Depot told you that your disconnect must be 6' or
closer to the spa, run, do not walk, away from that place. You were

grossly
mis informed.
For you spa to meet current code, you must have a GFCI breaker

protecting
the power to the spa. You can put this GFCI breaker in your main panel

if
you want to. A GFCI breaker is rather expensive, though, at maybe $80

or
more, depending on the brand of breaker you need. This breaker can go

in
your main panel if you want.


I don't believe this is always the case. If the spa has no underwater

light,
and this is a branch circuit and not a feeder, then a GFCI is not

required.
Its always a good idea, but not required. The rest of DaveG's information

is
correct -- spa disconnect must be no closer than 5', but must be within
sight of the tub (which means 50' or less and you can see it).

Sorry, but I respectfully disagree with you. A GFCI breaker is required
for any spa.
Even our whirlpool tub in our bathroom has to be put in on a GFCI protected
outlet.
And that tub has no lite. I'd think that any power outside of the dwelling
would need GFI protection to meet code.
If you spa has no lite, then you may use romex to power to the spa. If the
spa has a lite, then you are not allowed to use romex, and the entire run of
line must be in conduit.


As far as a step by step process:

1. Check with your power utility to determine their requirements for
electrical services. Mine has a web site where this document was located.
Much utility stuff is not regulated by the NEC, so you won't find it in

the
NEC code book.

2. Is your underground conduit sufficiently large to accomodate the wires
you need. I think you'll need a 1.25" or 1.5" conduit, but the utility

will
regulate this.

3. Evaluate your existing panel and the wire lengths of the circuits

coming
in. Will they reach their proper location in the new panel? Should the

panel
be mounted higher, lower, or the same?. Can you meet the meter height
restrictions while allowing most of the wires to reach the proper bus? You
can wire nut in the panel, but it is discouraged.

4. Evaluate your grounding system. Do you have a metal water pipe in

contact
with the earth for 10' or more? Do you have a ground rod or two? What size
wire is connected to your water pipe and ground rods (if you have them)?

These steps are what you need to evaluate in order to determine what the
next steps are. Once you've installe the meter main combination panel, the
utility may need to upgrade your transformer and/or service lateral wires

to
your house. This may or may not cost you money.

A surface mount panel is allowed, but look at where the wires must come in
and out of the panel. Generally, each cable should go through its own hole
with a clamp. Using a huge hole with a large NM cable clamp to hold all

your
existing circuit wires is not usually permitted, but you could ask your
inspector if this saves a lot of effort. I'd plan on removing some siding

on
each side of the panel and mount it in the wall like the old one. Or, use
the existing panel as a junction box and mount the new one next to it.

This
would be ugly, but workable.
