voltage reading on the nuetral

OK I hold my hand up. I never delete a drawing once done. You never know when you'll need it again.

OK please explain the physics behind the drawing I don't get it

as i see it, and i may be wrong, in a circuit under load, there is a certain volt drop. this VD is on the L and N, but the E is still at 0v. so there will be a small voltage differential between the N and E, relative to the VD of the circuit,

Didn't know Abu Hamza was a spark.Sorry couldn't pass on that one..

he may not be but i vote him as a prime candidate for 2000v.

How many Kv do you get through a HT on a Quad bike coil ? I split a HT circuit other day while it was running I was dancing around like a crack head with St Vitus dance much to the amusement of my 19 year old kid..FK me it hurt

He's not...

It's just 3 resistances in series, each one drops voltage across it.

Uo = Supply voltage
R1 = Resistance of Line conductor
Rn = Resistance of Neutral conductor
RL = Resistance of Load

Voltage across Line V1 = Uo * (R1/(R1+RL+R2))

Voltage across Load VL = Uo * (RL/(R1+RL+R2))

Voltage across Neutral Vn = Uo * (Rn/(R1+RL+R2))

V1 + VL + Vn = Uo

HT from coils is in the region of 15kV.

Check the connections at the main cutout end and look for joins and check the cable size. Your hair dryer may not operate properly on 214V.
