    Bad shock off Hot Tub.

    Got called out to look at a hot-tub. (reasonably new I think) which client was getting a shock off. Have tested everything up to the panel in the Hot Tub. RCD is fine although hasn't tripped when under load. It is when the main motor kicks in that water become's live. Most likely a fault with...

    Hot tub electric shock

    Hi I'm looking for some advice, yesterday when exiting my hot tub I felt a slight electric shock when my foot made contact with the ground around the hot tub. I work as a cable jointer so a tingle is second nature to me so I double checked when in contact with ground and water I can feel a...

    Get a shock when you touch sink and oven at same time??

    I understand this could be because there is no bonding, but just want to know how it’s possible for the pipework/sink to become live?? Is it through a fault on another circuit finding it’s way to the pipework?

    Shock from a consumer unit even after Safe Isolation!

    Not a big one, but it bloody hurt and scared the pants of me! If anyone reading the following knows why this happened I'm all ears. I safely isolated a garage consumer unit, but didn't turn off the associated MCB in the house, so the tails to the unit were still live, ready to put in a new...

    Shower shock in TT systems

    Do you encounter many issues with homeowners experiencing "tingling" from electric showers in homes with a TT supply system? Reason I ask is because everytime we respond to this issue it always turns out to be a result of a plumber replacing copper with Qualpex or the service provider replacing...

    So How Come A 30ms Rcd Is Supposed To Trip In Ms..

    Yet when you accidently touch it with human hands it is way longer. I've done this a few times in my clumsiness and it certainly does not trip in milliseconds! Just wondered what anybody else thinks.

    500v IR test shock?

    Advice on fatal current (research project)

    Hello, This question is purely for research purposes. In the event that an appliance (hairdryer) was dropped into a bath with a person on it, and a circuit breaker was tripped in the consumer unit, could this shock still prove fatal or would the breaker save their life? I know that this is...

    Wall switch electric shock when wiped down

    Hi, apologies if this is a daft question to ask but would really appreciate some advice. I wiped a light wall switch in the hall with an anti-bac wipe (dettol kind, so fair amount of wetness from the wipe unlike the cheap kind that can be fairly dry). When I wiped it, I accidentally flicked the...

    Hot Tub GFCI troubleshooting

    I am the homeowner of a hot tub that's been working for well for 6 years. One day the water began to provide a shocking sensation which would prevent you from putting your finger fully into the water. I determined the shock was coming from a 12V light mounted in the tub whose water seal had...

    What is the path current takes in an electric shock.

    Hi I am currently doing my electrical NVQ and have asked a few electricians this question and wanted to clear things up. If we touch an electrical conductor and are standing on the mass of earth will the current flow through us and back to the transformer or just dissipate into the ground. I’m...

    Shock from unplugged sewing machine lead

    Two of us have had a shock from a lead that had been disconnected from a Singer sewing machine several hours earlier. The machine is fairly new and not been heavily used. The shock was definitely stronger than just static. My concern particularly is that this is a machine being used with...
