kid sinister posted:Also, I don't know if they ever fixed it, but surge protectors from over 6 years ago that claimed to protect ethernet cables only protected pairs 2 and 3, while 1 and 4 weren't even connected inside. That means they effectively blocked gigabit ethernet. CSMA/CD is basically a thing of the past with switches. Most will connect at 1gig on 2 pairs of cat3 even if they aren't supposed to work since most runs are well below the 100 meter limit. You won't get reliable POE at the higher currents if that is a concern, notably if you have a high frequency ballast within eyeshot. 1000Base-TX removed the need for pairs 3 and 4.

The similar naming and the fact that 100Mbit was TX has led to a lot of mislabeled hardware on the internet claiming 1000Base-TX on 1000Base-T gear. I'm honestly not sure 1000Base-TX actually existed in a mainstream product. It was a joke, and I completely agree. I lurned something I'm going to reforget in a year. I am not afraid of being corrected on the internet. It's a common occurrence. The last time I was taught about ethernet those pairs were used for those function. I'm looking forward to the 2.5ghz base bands coming out. 2.5x the speed on the same cables!

Super Waffle posted:Question for you guys. I've recently wired up my shed with two 120v 20 amp circuits split up from a single 30 amp 240v line. I have the shop lights on one circuit and my miter saw on another circuit. When I turn my miter saw on the inrush current causes the lights to dim for a moment. I would have expected this if they were on the same circuit, but I am confused as to why this is the case if they are on completely different breakers. Both circuits share a neutral. What would cause this and should I be worried? Wait for the blade to get up to speed before putting load on it. Largely so you can see what you're cutting. Not that my lights do that or anything.

EvilJoven posted:70 amp fuse panel - already in the works to be replaced If you can afford it I would have a professional take on 4 or 5. Once you start jostling the old wires the insulation is likely to come crumbling off leaving you with what amounts to knob and tube, but without the knobs. At least, that is what's happened in my anecdotal experience in a 1946 house with rubber+cloth insulated wire. A professional will be able to bang out the job in a much shorter period of time, and you will hopefully then have an up to code consistent set of wires in your house, a new panel with room to grow, and more amps of service. A professional will also help you not get dinged for insurance fraud in option 5. Ours starts Oct 3, they estimate the dust settling by Oct 7. 1250 sq ft, including a trench to the garage. $9,300, los angeles county CA, highest rated electrician in the city, and literally our neighbors we came to find out.

I did just notice by chance that our outlet for the microwave/exhaust/light combo unit is only a 15A still which is obnoxious. Didn't think of it until I saw it lacked the T.

With how anxious I was with the inspector coming out to check the stuff I'd paid a professional to do, I can't imagine how nerve-wracking a whole-home rewire would be. Honestly the inspection didn't make me nervous in the least. Whole lot of not my problem, we had a contract with payment contingent on passing final inspection. Heck, his mother was the one doing the walk through with the city inspector. Once I saw the work underway it seemed to all be correct at an eyeball, I was mostly worried about just how much plaster they were going to knock out to get the wires pulled. Now, when I start fiddling with the garage and my own work, then I will be plenty nervous. I don't have any rapport with the inspector other than whatever tiny amount I gain pouring money into improving a property within the city "by the book."

Yu-Gi-Ho! posted:Any idea WTF? Is this just normal for one without a battery backup? I'd never seen an AC powered one without a battery backup, but I looked up the model # on it, and nope.. no place to put a battery (they made a version that did have that provision though). Or should I just go ahead and replace it with one that actually does have a battery backup? It's line voltage, not interconnected to anything, though the building does have a (pull station only) fire alarm. When the place was built, only one was required, AFAIK. The detector itself is right at 10 years old, building is 32 years old. Are you sure it doesn't have a 10 year lifetime lithium battery in it? That is the new hotness (and what I think everyone should install) as detectors only live for 10 years. If there isn't a newer date written on for installation tell them flatly it's an expired detector and your renters insurance is complaining. Which they will once you ask them about it. Otherwise I don't know if they make them with capacitors in them for transient power outages?

kid sinister posted:What do you mean by "the new one comes with a junction box to go into the under sink cabinet."? In the US, dishwashers are either hard wired, or they have a cord and plug that plugs into and outlet under the sink. I assume it is a hardwire kit. Ours came with both. There is a modular plug in the back of our dishwasher for hooking them up. Our electrician wired a duplex outlet with a dedicated circuit for each thing and put a bar across the breakers so they both flip in tandem.

You know thinking it through, I am not sure if my dishwasher is GFCI. Which makes me wonder what else they missed rewiring the house. The bid says "Wired to National Eletcric Code" and proper permits were pulled/signed off on by the city. I'll go double check my box when it's not raining, but I seem to recall only 2 "reset" buttons in it for AFCI. I just went and tested all the GFCI's I could find in the kitchen and none of them turned off the dishwasher, or the outlet we use for the toaster for that matter. (Which is far away from the sink, but in the kitchen.) This is what happens when your neighbors are the most highly rated electricians on yelp for your area and actually pick up the phone to bid your job.

Is there a cold start capacitor in there or something similar? That failing can cause units to fail to start or draw excessive power for longer than "instant" when it kicks on.

I hoped not to be back here so soon after a whole home rewire but here we are with fun discoveries. I am hoping to install a Leviton light controller with magic sunrise/sunset calculator inside it to replace a simple toggle switch. Seems easy enough, Black - power, white - neutral bundle, red - fixture, green - ground bundle, yellow/red - leave. New nuts all around. The double gang original metal box also has a 3-way dimmer in it. I pulled it all apart and found that the box does not at a glance appear to be grounded (no green ground screw, no wire serving that purpose regardless) and the toggle switch I am replacing has a green ground screw which is not hooked up. It is not to my knowledge self grounding and due to the plaster the metal on the switches doesn't make contact except through their retaining screws. The bare ground wires are crimped together vs nutted which I assume is fine. Box: Diagram, less ground. The wires are numbered left to right as you see them in the box, cable #3 is to the left and behind of cable #4 on the right. It's hard to see, I promise you it's there. Is this a fools errand space wise? I wisely did not check prior to buying this switch. Is the box is supposed to be grounded? All 5 grounds are crimped together across two crimps, with one of the wires from the first crimp extending to the second crimp. Fixing the ground means opening up all the rest of my boxes, I'm going to spot check a couple known metal boxes and if they aren't correct I'm going to call our electrician to come out and verify the rest of them while looming over him. God dammit. The blacks are indeed power based on my contactless meter. I ran out of time to do anything else and didn't want to risk it not fitting regardless so I just put it all back how I found it. H110Hawk fucked around with this message at 19:03 on Jan 3, 2017 |

The 12-2 was existing for our ceiling light fixtures based on previous pictures of the attic. I don't necessarily blame him for not re-doing the 12-2 pull. I do not see any bushings. For fill I put in 4x #14, 1x #12, 2 gangs, for the device connection and grounding do I put #12 or #14? http://www.constructionmonkey.com/calculations/electrical/boxfill For the box grounding there is enough sticking past the crimped fitting I believe I can get one of the wires around a green grounding screw in the back of the box. I bought a package of them and some push-on connectors after being corrected by Mstr Sinister regarding the latter. I'll pull open a few other boxes to check them Soon™. Ugh.
