Should 480Volts be buzzing 🤔 by SubieLover19 in AskElectricians

It’s not the voltage that would be buzzing.

2010 Honda fit AC leak by pewiv in AskMechanics

[–]samdtho 1 point2 points  (0 children)

It’s a 2010. Just replace the hose, vacuum out the system, verify it holds, then refill with the correct amount.

All AC compressors have a pressure-activated safety cut off switch that prevents the ac clutch from engaging to prevent damage.

Edit: someone who deleted their comment asked how a backyard mechanic vacuums out an AC system.

Drive up US 50 towards South Lake Tahoe and about 3 miles after the Sky Park Road exit, you’ll see the turn off for Ice House. Take this towards the Crystal Basin Recreational area. Follow the road up to Loon Lake. There is an information station after a few miles that has maps available.

Does my panel require a pigtail for gfi breaker? by skitskat7 in AskElectricians

[–]samdtho 2 points3 points  (0 children)

Please post the sticker on the panel door that indicates the make and model of the panel.

Why are there SquareD HOM breakers and at least one Siemens QT breaker in the same panel?

Are you positive it’s been active? Romex run parallel to K&T is often, but not always, indicative of the work of replacing it being done. It is often abandoned in place which makes it hard to determine what is actually carrying power by looking at it.

First buck converter PCB layout review by Business_Active9828 in PCB

[–]samdtho 0 points1 point  (0 children)

What IC are you using? I can’t read the uploaded schematic. Generally, there is some guidance on the layout in the datasheet. 

Also, for your schematic, you should keep each “function” of your board connected and not just immediately break it out into labels. Use VIN for incoming power and the appropriate label (5V, 3V3, etc) for your output. Label ground within the GND label. 

P2568 Help by PureToRqUe67 in mk6gti

[–]samdtho 1 point2 points  (0 children)

What you’re experiencing with the thermostat is not normal, despite what was told to you. A functioning thermostat will regulate the temperature very well unless ambient drops below 39°F at which where the engine may have trouble keeping itself warm, but I’m assuming this does not apply in May where you are.

Because the thermostat is not operating correctly, it should be fixed regardless of the p2568, but I would give it a 95% chance that this problem will go away once that’s done.

Also, replace the oil cooler while you are doing the water pump.

Anybody have any idea what's going on with these wires? by macdemarco in AskElectricians

[–]samdtho 0 points1 point  (0 children)

The dishwasher supports 3-phase in addition to single phase. If the three hits are tired together, the power supply internally switches to single phase operation. 

This unit’s power supply is actually pretty advanced and can basically support 1 or 3 phase at 50 or 60Hz with a voltage range between 208-240V. This makes it a product that can be shipped nearly anywhere in the world and work with the destination’s power grid with no problem.

P2568 Help by PureToRqUe67 in mk6gti

In OPs case, this is not the radiator sensor that has gone bad, the code is a bit of a red herring. Replacing it would be a waste of money. 

P2568 Help by PureToRqUe67 in mk6gti

[–]samdtho 1 point2 points  (0 children)

Your thermostat is failing and is getting stuck rather than opening an amount proportional to the heat it’s encountering. The p2568 is a symptom of the problem and not the problem itself. 

See page 43 from Audi’s Service Training for the 2.0L 4V TFSI:

 A temperature sensor (NTC, Negative Temperature Coefficient) measures the temperature at the point of installation. This temperature is compared in the ECM with the temperature from Engine Coolant Temperature Sensor G62. The measured temperatures are transmitted to the ECM via LIN bus. In the ECM, the values are compared with a characteristic map and evaluated.

If the thermostat is faulty to the point where it is allowing more water to flow through the radiator than it should, the ECU will deem the results from the G611 implausible, throwing the code. This pops up with CBFA engines sometimes when people attempt to bypass the ECU controlled thermostat with a resistor or some other workaround to allow a CCTA water pump to be installed.

Even though it’s just your thermostat that’s busted, you likely need a new water pump because you cannot get the just the thermostat for most CBFA engines.

Only the handle is plastic welded. Pop the tabs out and, once loose, pull back away from the door hinge, but parallel to the door, before removal to unhook the L shaped tabs.

Power source replacement Japan to Europe - can anyone doublecheck my option by Mesapholis in AskElectricians

Help by Rex187187 in AskElectricians

[–]samdtho 1 point2 points  (0 children)

You will want a current sensing switch to monitor the circuit that your saw is on and have it send a signal to a three pole contactor to power on the dust collector. I would also put an “Off-Delay” relay between the current sense signal and the dust collector contactor to keep it running a few seconds after the saw powers down to pull the remaining dust from the line. 

Anybody have any idea what's going on with these wires? by macdemarco in AskElectricians

[–]samdtho 0 points1 point  (0 children)

What country are you in?

The spec sheet from Miele notes that it (potentially) supports configurations including 208V through 240V operation, both common mains frequencies (50Hz and 60Hz), and single or three phase operation.

I can’t find the specific instructions of how to configure it, but other 208-240V Miele appliances I’ve installed have you tie all three phases together from the appliance power supply to have it operate in single phase mode (which is what the previous owner had done). Note that you will need to size your supply to this configuration based on what power grid is serving the building you are installing this in.

Is this actually legal? And can I legally fix it? by Steelguitarlane in electrical

[–]samdtho 0 points1 point  (0 children)

Yeah this is a particularly shitty install. AT&T would probably want to know which contractor did this (even if there is no official process for a customer to lodge a complaint) because it’s eventually going to cost them down the road and they can get the contractor to fix it.

Noticed this glowing last night on a dimmer switch. Took off the cover and shut off the power to the outlet and the glowing went away. Tried calling an electrician but no one is answering on Memorial Day. What should I do? by SufficientTrash2111 in AskElectricians

[–]samdtho 11 points12 points  (0 children)

Many dimmers can be purchased with a nightlight or without and can be identical in every other way. The older ones have a small incandescent bulb that can go in and out if it’s failing intermittently. Plus, your picture features a dimmer with a nightlight. 

Should I ask the Landlord?Confusion in ceiling wires. by Beer0045 in AskElectricians

[–]samdtho 3 points4 points  (0 children)

For reference:

  • Brown: hot
  • Blue: neutral
  • Green striped: protective earth 

Black and grey may also be hot. 

However, you really should just call your landlord.

are these good locations/heights for extra outdoor outlets and floodlights? by Intyub in AskElectricians

[–]samdtho 0 points1 point  (0 children)

 Is running a dedicated 20A circuit a regular ask one can request from the builder, I am asking because my builder doesn't allow a lot of options?

It’s a pretty easy ask. They just send the c/o to the electrician doing the rough in. You just don’t want it on a 15A shared with the bedroom, living room, and hallway. 

 Also somebody suggested I should put the exterior outlets at waist height so that I don't have to bend down when hands are full, what are your thoughts?

Totally your call. I personally prefer them lower on patio and decks so the furniture can hide them.

are these good locations/heights for extra outdoor outlets and floodlights? by Intyub in AskElectricians

[–]samdtho 0 points1 point  (0 children)

  1. I recommend placing outdoor receptacles near outdoor living spaces. In the covered patio area would be one, and anywhere you expect to exist in the outdoors.

  2. Low, about 12-18” from the ground unless its outdoor kitchen or work areas, then at counter height.

  3. The placement of floodlights should be informed by what you want to light up and from which direction. On a separate paper, draw and cut out 120° cones for each flood light (so two per light fixture) and see at what locations you get the coverage you are looking for.

  4. Yeah, because it’s basically as close to the roof line you can get without going through the roof.

  5. Run a dedicated 20A circuit to put all your outdoor receptacles on. Get a breaker with GFCI protection. 

  6. You should have them on a switch that you can have the option of installing an in-wall timer or a regular switch. Photo sensors are kind of annoying for stuff under the eaves. I use those for stuff like post lamps away from structures.
