    I don't know if this applies for the EU. We do have a common rule of thumb where the hot should be, but loads could be connected eather way. Sooo…. idk

    How do you test the GFCI wires to verify you shut off the correct breaker so I don't have to flip the main off? I own both a multimeter and a car test light (for fuses)

    I once accidentally touched my alternator when my car was running, tossed me back 10 feet like a rag doll, I've never worked with anything electric when powered on since

    I just changed a GFCI 5 wire, a ground, 2 lines and 2 loads and my "8-ball" reads hot neutral reversed, . This outlet runs a garage- located refrigerator and 2 2nd floor bathroom outlets. Are my line wires reversed or my load wires to get a "hot neutral reversed" reading? I know for certain my lines are up top and and loads are on the bottom, I just didnt realize the left and right could be reversed. Can I run into any problems if it takes me a day or two to address this? Thanks much

    There are brass terminals for hot silver terminals for neutral and a green terminal for the ground wire. If installing a GFCI outlet or receptacle do not get the line and load mixed up and if there are multiple GFCI outlets on a circuit then do not use the load

    Great explanation. The speed of delivery is to slow. Can you redo the video a little less mono tone.

    Polarity is a function of a Direct Current Circuit – think battery power.
    Alternating Current (A/C) – in the US – consists of two 'HOT' wires (RED & Black) and a neutral (White) wire and a (Bare Copper) Ground Wire entering your Electrical panel. The ground is actually connected to the ground your house/home sits on (either by a grounding connection to buried metal water pipes or to a ground rod buried six feet or so into the ground.

    Hot and Ground are appropriate terms when discussing alternating current – rather than POLARITY (the relative orientation of poles; the direction of a magnetic or electric field) which is a term that has meaning when discussing Direct Current (think battery powered) circuits.

    This was a great video amongst thousands. Much clarity than ever. First time I got the inside real story of polarity reversal. In DIY, I did install one outlet and I have to check its polarity ASAP. Thanks for this video.

    This was great, thank you! I hired and electrician to do my fix but the first thing he asked was to suggest testing with the 'cube'. What a cheap great investment, less than $5. After finding reverse polarity in 3 adjacent duplex receptacles, I was able to further talk with my electrician and get a head start on troubleshooting.

    Just tested every outlet in my home. My home is at least 30 years old. One outlet in the kitchen, one I plug in the coffee maker, tested reverse polarity. One of my outlets in the living room showed an open ground. You are right, the one in the kitchen seemed to work fine. I didn't know anything was wrong. Fixing it and the open ground this weekend.

    Hi my four pin plug was damaged (clips snapped) on my car radiator fan motor my friend put a new plug on on the car rad loom which is 12 V car electrics- three settings on fan 100 250 450 – anyway he got the red and brown wire incorrect way into plug so I guess reverse polarity – it started smoking the motor and unplugged it after a few seconds – question is the cables where changed back to the right sockets and the fan now works perfectly – iy was a £400 fan my question is please the fan is working good but would he of damaged it as went very hot and smoked- the plugs were perfect and not burnt – thank you.
