Ask an Electrician anything...

[ruggedscotty]

Well another thread for those questions you always wanted to ask a sparkie

[Paynewright]

Why do stainless cooker hoods not need an earth? (Just purchased a new SMEG appliance and only has brown & blue wires).

I remember a fatality at work where one of the gas engineers put his hand on a metal hood in a customers house and it was live!

[Saleen836]

Why do sparkies never clean up after themselves on site?

[Simodbod]

Thanks for your insight

Why do sparkies leave the switches on in plug sockets when nothing is plugged in?

if the cooker hood is Class II its said to be double insulated so will not require an earth.

CLASS II EQUIPMENT
Equipment in which protection against electric shock does not rely on basic insulation only, but in which additional safety precautions such as supplementary insulation are provided, there being no provision for the connection of exposed metalwork of the equipment to a protective conductor and no reliance upon precautions to be taken in the fixed wiring of the installation.

Have you ever worked on anything that requires 1.21 gigawatts of power?

not quite as large as that. maybe a dropped spanner across a set of bare busbars would have taken that for a split second lol

Serious: what is the difference between single and 3 phase?

Oh, and what is electricity?

Why do you always park your vans directly outside the house that you're working on, on new build sites, making it impossible for HGVs to get through?

difference in number of wires and the voltages will be different. With three phase the voltages all have the same frequency but are separated by a time difference of a third.

single phase has 240v ac to neutral same as three phase to neutral. but across the phase you have 415v just the way that its generated, the physical difference between the phase windings on the rotor. etc.

Electricity - its a flow of molecular matter. dc it flows around a circuit. ac it vibrates in a circuit.

Isn't it the flow of electrons, i.e. subatomic particles?

Do you all still think you're top of the trades, when in reality, there's more skilled trades out there?
