Time to get back into the major work as write-ups are still lagging actual progress.
200 Amp service upgrade
For many folks electrical upgrades are novice territory. Well it was hard for me. Wiring cars and DC voltage is fine, but when you start talking AC and circuits with color conventions that mean different things in different applications and it’s just no bueno. I can stare a crusty old circuits for longer than I care to admit and still not be sure I have it right. At the same time, I am a pretty handy guy and I’m operating on a budget so I wanted to do as much as I could.
I hit up my electrician friend at church (the one who helped walk me through setting up the branched circuits for my lights). Given what I wanted to do, I really needed to upgrade my electrical service from the 100 Amp service my home come with, that which was installed when built back in ~1969].
Basics steps are as follows:
• Contact utilities provider (So Cal Edison in my case) and have them inspect whether an upgrade is an option based upon existing infrastructure. They can pull new infrastructure from the local transformer but the cost goes way through the roof if you have to. Thankfully, they approved me for 200A and I had 1 year to complete the work.
• Pull permit from the Local City hall Building Dept. Home owner can do this but it’ll raise less eyebrows if an electrician w/ contractor’s license does so on your behalf.
• Perform electrical work.
• Patch around the panel (stucco guy).
• Schedule city post inspection. City notifies utilities provider.
A service upgrade is an all day affair for two guys so we were well out of the realm of favors for the work. Also my friend had hurt his knee recently so it wasn’t a good option for him to help. Anyways, I still got hooked up as he let me use one of his guys as a side job w/o any overhead. I was the 2nd guy and served as lackey.
Starting point:
1969 wiring confirmed.
There are a metric ton of custom tools needed for this job so I recommend calling in the pros. Mini jack hammers, impact drills with non-standard masonry bits, conduit benders, crazy connnectors not available at your standard big box hardware stores… Never been so happy to pass a guy $500. What a nightmare.
A quick note on main panels. There’s a line in the existing electric code that references that a second energy source shall always be installed on the opposite end as the standard feed. This means if you ever think you might add solar it’s smart to avoid the center feed panels and get one that feeds from the end. The code may get clarified at some point but for now there is no “opposite end” on a center feed panel.
The meter is one of the few things that gets reused.
Anyways, while my electrician was tearing apart the side of the house I was put to work running a new/massive ground. Kinda a duh moment for me, but installing a new ground meant driving two ~8’ poles into the ground. The mini electric jackhammer is super useful here.
One is around the corner in front of the garage. The other is driven in near my home’s water supply main (and connects to that as well)
I ran this around the perimeter of the garage through these small 1” tall triangular openings between my attic joists and rafters. The ground is jacketed, kind of like a heavier version of MC cable so it tries to snag on the openings constantly. I probably spent 2 hours getting the 60’ of cable dragged into position 2-3 inches at a time. Fun stuff and a heck of a workout.
One thing I don’t have pictures of was the two of us fighting to get the existing the main conduit (big ***** 2.5” or 3” rigid conduit) aligned to the new sub panel. It needed to be over about 3/8” from prior and it looked like it had enough flexibility to get there but it was damn hard to both push it over and get the internal jam nut started.
I ended up contributing a tool to the mix and we used my high reach 4x4 jack to pull and hold this in position. Felt solid about overcoming the hurdle. But hey, it was a mechanical problem. Those hurdles are surmountable.
Last step of the day was having me throwing breakers over and over while we figured out what went where inside. I broke out the label maker sometime after this.
Stucco patch work is a different contractor but my electrician friend got me a referral and a deal. Tack on an extra $250 (the gent even painted it for me) and things were starting to look tidy again. The stucco guy was bragging how he’s been setting rates in our area as typically it’s a $400 job and given the work involved and artistry required I believe it.
I went back after the fact and took a few pictures of internals. Mighty fine work. Heck, even the service loops are tidy.
Dielectric grease on connections. Really really stellar work.
End result:
Looking at this pic vs. the hole it was above, I'm all kinds of impressed with the Stucco guy I was referred to. If anyone needs a referral in Orange Count CA, let me know.
By the way, the box up top is the run to the sub panel inside the garage. That happened in round 2 which I’ll be writing about shortly.
To this point I was in give or take $600 in material and $750 for labor (electric and stucco). With overhead and markups (which I didn’t pay) I was told $3000-$4000 is more normal. Given we both worked our asses off for a full 10 hour day, I believe it.
