Electrical symbols

[Sparkystu79]

Does anyone know where I can find a comprehensive list of all the symbols architects use on plans? Have a job to price and some of the symbols are new to me and there's no legend!

Most of em are on the inside of the back cover of the OSG.

It's not on that list,I'm beginning to think the architect has used some artistic license!

symbols do vary between architects so whoever gave you your drawing go back to them for your info you require

BS 3939 has been superseded by BS EN 60617 (IEC 60617). Look here for the symbols, note you will need Java to render pages:

Hi everyone I'm new to the forum,
I could use a hand if anyone is game, I'm an apprentice H+V service and maintenance engineer. This is part of a assignment I have been given. In the photo below there is a control circuit for a shunt pump. I understand that to the left under where it says shunt there is a selector switch. My confusion is with the next component to the right of it. It is a single pole, double throw switch. What I don't understand is the means of actuation of that switch, the coloured part of the switch symbol above and the letters O/L (online? overload? open loop?). I think it must have something to do with the over load of the shunt pump. Perhaps an auxiliary switch on the overload, where if the overload trips then it would take the contactor "S1" out and display a fail lamp "IL16". I have been scouring the net for hours and I can't find a match for the symbol for that switch. So really I need to know what that symbol represents and what the O/L stands for.






Many thanks



Julius

Hi Juls,

the component to the right ( marked OL) is the auxilliary contact of the motor overload switch, the component to the left ( SW9 )iis the selector switch.
It has three positions pump 1,off, pump 2.
