I am wiring into a 3 phase 208v busbar. I want to split each phase to 120v with the neutral. I have no "wild leg". I am using 10 ga stranded copper wire for the 3 hots and the neutral. My loads consist of 20A on L1, 20A on L2, and 10A on L3. I want to know what the current will be on the neutral. If I can use the single existing 10 ga wire for each leg (30 amp capacity)? If I need to worry about harmonics?

In science class we were assigned a project that will last the rest of the quarter. We have to build a tomato launcher that will be able to launch a tomato 25 yards. I am building a trebuchet with some plans I found on the internet. What kind of tomatoes will not explode when I fling them?

If you could tell me what harmonics caused the distortion and the actual THD value that'd be nice. I tried having a look on the net to no avail. I would like to know what the sine wave at the socket in my house would look like too, I would not expect it to be perfect but I don't know how far from perfect to expect.
THANKS!!

Hi,
For the last 3 years I've been working as an electrical engineer on a blue chip company (R&D). lately I'm thinking about shifting to a field application engineer (FAE) position, since I'm interested on learning the business and customer side, but I have few worries:
Am I overqualified? - is this job more appointed for people with less technical knowledge (technicians etc.)?
Does this position has a bad "reputation" and is it less overrated?
Could it hurt my career, for the long term, if I decide to go back to R&D?
Thanks.
