Schematic Dwgs

[runna]

Hi,

I've recently crossed over from mech to elec due to the sudden resignation of one of our senior electrical techs. This is only a temp position until his slot is filled and I am only operating rather than the technical side of things however, I would like to get a handle on reading electrical dwgs; a). to be able to help out fault finding and, b). so as to not look like too much of a plank!

Can anyone help me with conventions and/or any links or docs which may be of use...thanx in advance..

Had a very quick look online and found some links that might be useful to you (they are all from

http://www.faqs.com):

Circuit schematic symbols:

http://www.faqs.org/docs/electric/Ref/REF_9.html

Resistor colour codes:

http://www.faqs.org/docs/electric/Ref/REF_2.html

Some circuit theory:

http://www.faqs.org/docs/electric/Ref/REF_1.html

Hope something there is useful to you.

DISCLAIMER: I have not fully read the links above and have no idea whether they are fully accurate - use at your own risk...

Ugly's Electrical References (ISBN 0962322970) is a handy little concise reference book on electrical topics.

Good luck.


Expactation is the mother of disappointment.

I just looked at the schematic link. What A load of rubbish. Hump back bridges in circuit diagrams are indeed obsolete. The way the junction is handled is that you NEVER join 4 branches at one node. This way a cross-over is unique, even if there is an unintentional blob caused by a copying machine. In other words T-junctions are the maximum (3 branches) number of branches at any node.
