Hello
Have a ring doorbell which is powered from the mains using the ring branded transformer that came with the unit.
Its been working well for about 2 months since it was installed by an electrician and then just failed last week and appears as though no power is reaching it.
I used a...
Hi,
I'm currently doing my assignment for 2357 and was just making sure I'm calculating the cable length for the lighting circuits right. As depending which way you do it, it alters the voltage drop a bit.
On the drawings I've looped in and out at the switches all the way to the final light...
Came across a weird one today…
Four single black stranded 12gaTHHN running through 1/2” conduit about 40’ to first outlet box and 70’ to the last, on a branch from main panel. One 20A breaker and one 30A breaker. The homeowner asked to eliminate existing locations and reroute, no problem. I...
Hi all,
This is my first time posting something on this forum. I'm busy putting together a design for some LED lights that are going to be mounted on some columns along a pathway. The supply will run twenty odd metres to an enclosure on the outside of the building that will encase the...
I extended a bedroom in my basement and had to move a couple outlets from the knocked down wall to the new wall.
After, I was sanding down the drywall mud and forgot to completely shut the door of the main panel (which is in the corner of the room).
Soon after, I went upstairs and noticed the...
My first question, so be nice. I'm very sensitive.
We use 230 volts as the go to figure when doing calculations on single phase.
However on page 362 of the regs, they squeeze in another voltage to use on the bottom of the page. Namely 218.5 volts (95%).
It's when calculating Zs. I can't...
I'm trying to test if there's voltage between my ignition and the solenoid. The starter won't crank or click so figured I'd start here but am not sure if I'm doing this correctly. I have a male/female connector from the ignition to the solenoid. I disconnected this, connected a probe to the...
Currently I have 4 small low voltage transformers connected to 4 circuits of low voltage yard lights. They are under my deck, and I turn then on and off using switches above the deck.
I want to consolidate those transformers into one transformer...
Customer has leads . SO its test , remove transformers .Hook up fly leads etc . Nothing to high and not bad access etc .
What price per point do you think ? (30 in total )
I do general maintenance at a summer camp that includes a campground. One of our campsite electric posts is having a problem. The GFCI is tripped and will not reset. I tried a new GFCI outlet and same result. I'm also getting about 2.6v from neutral to ground, when measured at the outlet and at...
Im making a led array out of 8 100 watt led's and I want to put something in between my battery pack and the array that can adjust the voltage coming from the battery and also shows the voltage. I was wondering if someone could help me find something that can withstand the power demands the...
While sorting out some issues with immersions at a flat yesterday, I ran into something that seemed peculiar (to me at least).
Immersions need new thermostats/cut out, all quite normal..
However, while testing the lower (off peak) immersion I was getting 13V L-N - which I assumed was just my...
Good afternoon, a colleague of mine has recently had three brand new Bosch washing machines pack up, each within four weeks of being installed.
I did a check on the voltage and it's 246.3v. Surely this shouldn't have had an effect on the machines...?
Bosch seem quite happy to keep replacing them...
Hi there.
I’m looking for some professional advice.
I recently bought Beko Cooker model KDC653S, it doesn’t come with the electricity cable and according to the manual it require H05W-FG 3X4mm or equivalent with total power consumption of 10KW.
I called all local shops including electricity...
Hi there,
I recently bought a Worksharp mk2 knife sharpener. Got it shipped from the US so I need an adapter for it here in Aus. The sharpener is meant for 115v 60hz power supplies only. In Australia the voltage rating of most households is 230v 50hz I believe?
I think I need some sort of step...
Hi ther
I'm fitting a new IKEA kitchen for my father and have insta Ed a new cooker switch. When testing with cooker breaker off I was sill seeing 9.6v on my multimeter. As I individually switched other breakers off I saw the voltage decrease witheach breaker till i switched off the main...
So for the longest time I had issues in this location while gaming. I am on a second pc build that exhibits the same weirdness that made me actually quit playing Fifa though I loved the game. To use a simple clear example of weird behaviour, a game like Rocket League (maybe some have heard of...
Sorry this question may sound silly, but I really don't know anything about electricity so I'm just asking to make sure.
So, recently I bought a machine from the U.S via Amazon. In the instructions of the Amazon page, it said to plug the machine into a 110V socket, but our countries run on a...
My brain has been exercised a bit by this. Am I on the right lines with this extremely simplified example:
If we take:
-TNCS installation with a Ze of 0.2 ohms.
-Plastic services, nothing bonded, keeping it simple
-Line conductor resistance from supply transformer should be similar to PEFC and...
