House Maths

So, we’re moving the fuse box electrical panel (and replacing the shonky crappy old panel. I’ve spent this morning sat working through this document that allows you to check the rating required for your service. I’d been thinking we might need to go up to a 300A supply, but it seems like 200A should be fine, which is pleasing. This is probably because the stove appears to be a fan-gas oven, which confuses the pants off me.

So the electrical loads that would normally be consumed by cooking stuff have disappeared into the gas. Which helps.

The sums work out at 96A which seems low to me, but that’s what the maths says. And I guess we normally charge at night when other loads tend not to be in use, so it probably works out fine.

I’ve also been trying to do load balancing. This whole 110v m’larkey makes wiring waaaay more complex.

UK: Incoming power -> RCDs -> Bunch of ring mains (lights, sockets, some single runs to specific appliances). Bob’s your uncle.
US: Incoming power -> Breakers of lots of different flavours -> Many spurs that all have to be balanced so that each of the two (120v) legs of the 240v gets roughly the same current draw + 240v loads that pull off both. You may be able to get an uncle called Robertish if you’re lucky.

So that means sitting down and trying to work out what groups of sockets and appliances are ‘likely’ to be on at the same time and then trying to organise them. Without just generating a billion different circuits. Then add in my desire to keep lighting and electrical outlets mainly on separate breakers (not required, but preferable). Then add in code requirements for specific areas to have specific kinds of breakers, or the dishwasher to have it’s own separate circuit… which it probably needs anyway in terms of power demands, but still…

…gah.

Of course this might all be punishment for the pre-regulation the-entire-kitchen-converges-on-one-socket design that I left in place in the first house I worked on in Bristol. I didn’t *make* it that way, but I didn’t fix it either. Just shoved all the wires back in the back of the socket and said “yeah, that’ll work”. I suspect it got fearsomely hot if you ran the washer/dryer and the oven at the same time.

Anyhow, since I’m not going to be doing that again and this is to be better planned, then I’ve spent some time on it. Hopefully it will work as recent calculations mean that I think I’m wiring the panel and just getting someone else to do the actual moving of the service / installation of the weatherhead… Technically, we could do that too, but I value my hands and my life :)

At any rate, I’m planning to submit the permit today – if we get the Rav back in time (it’s getting a new driver’s door lock, the old one having died).

In other house news, the smell of urine seems to be decreasing. We’ve removed the chipboard that covered the lounge, the hall, the kitchen and one bedroom. All that’s left is a bit of chipboard under the kitchen unit that we’ve not yet removed, the back bedroom and a small front cupboard. Spraying near a full bottle of urine odour remover onto the worst staining and the front step – along with a moderate amount of vinegar – seems to have helped too. I can now go in the house without wanting to run even when the windows have been closed. It just smells of musty old house and crawlspace.

Hopefully when we put down the vapour barrierey underlaymenty stuff that will resolve it completely. Although we’re planning to replace some of the worst car decking with new – and there’s one section which has broken.I’m guessing it’s rotted away under the end of the bath… but when I was lifting the chipboard I levered against it and it descended rather than the chipboard (with tile) coming up.

And in other, other news, I fell for a scam.

It took about a minute for me to twig and undo it, I think. About half a second for me to go “oh, you fucking idiot” and then the rest of that minute in a panicked google search and settings adjustment.

I listed our Insight on Craigslist, then got a message from someone saying they were interested, and could they call. Then I got a message saying that I needed to enter a two digit authentication code to speak to the craigslist person. I was somewhat suspicious – but after the person had tried a couple of times and I’d got messages each time I thought “well, what could I lose – I’m giving them information they’re giving me”. Apparently – this is a means of getting access to your phone number because when I entered it I got a Google Voice message – and allowing them to use it.

Thankfully, the answer is here. So within about half a minute I’d reclaimed my lost number. I’m hoping that the dickhead who did it didn’t manage to do anything useful with it.

After about 15 calls from the irritant, (s)he seems to have stopped. But it’s just f’kin annoying. I also am feeling a bit pissy because the Honda Forum seemed to think that the price was reasonable for the car, but now it’s been on there for a week I’ve had nary a bite. This may mean that all my sums about us replacing the car with an EV have to be reworked. If we have to drop the price of Insight to sell it…

Feh.

And in other, other news, I realised I should have ordered a smaller shift key when I ordered the keys for my keyboard. I did a test assembly of the kit which went fine, but I’ve not soldered it yet because I need the key tops to ensure that the layout I’m planning will work with the keys I’ve bought. It’s still very pretty though. It shall be super pretty when it arrives.

I just need to etch the CTL logo into it.

CTL terminal (in very fetching orange and black)

I just wish I could get an orange fabric covered curly keyboard cable to use. They don’t seem to exist :(
