Electrical Panel Help!

[dj digigrow]

I'm putting in a 40A Double pole breaker as well as a regular 20a bereaker.. I have just enough space to fit them.. my questions are:
Across from where I'm putting the 40A breaker are to single 20A breakers, is this fine??.
and across from the 20A that I'm putting in is a 15a breaker..
also is 10awg enough for the 40a beaker?
I think it calls for #8 no??
thanks....

Should be fine but you need to be fusing #8 AWG with a 40A breaker,by code #10AWG must be fuse with a 30A OC device.Don't add breaker ratings but add up total expected load in panel to make sure it doesnt exceed safe limits for the line wire feeding the panel.

fusing?

Just an electrical term meaning protecting.You fuse a conductor with an overcurrect device be it a circuit breaker or fuses

o.k, the 40a is to power up an a/c 18kbtu that draws 9.9amps and maybe 2000watts of light... this should be fine right??
so I have to go #8 for the 40amp right??

8 guage is good on a 40a breaker.
but you dont want to draw more than 80% of that breaker rating.
80% of 40 = 32A
2000w of light is about about 20A at 120v
10A at 240v
amperage for the lighting is a ballpark number, depends on what kinda light your using.

Thats what the American said lad, If I am correct he is a bona fide journeyman sparky person (correct me if wrong).

Well DJ being a journeyman electrician is one hell of a fine job to have, the IBEW is strong, wages and benefits packages are tops. I wish you the best for your apprenticeship. It is not easy, don't give up its worth every damned bit of it.

PS: Then you can advise the bone heads in here one day too. lol

If you have a chance to go through union apprenticeship its great in some places,not so good in others.I was lucky to go through IBEW local #26 in Wash DC,now that I'm down in Florida I wouldnt go near the local down here.Either way to pass your test the first time around take NEC code classes and order Tom Henry journeyman elec workbooks and be prepared because the test is designed to deceive.
