One more question - the basement's unfinished, so the joists are bare; is it code to drill holes thru each joist to run the line thru? I see a mix of that and stapling the wire to the underside of the joists. It would mean me drilling more holes, not enough space in the existing holes
If wire is number 12 you can put a 20 amp breaker in safely again keep it at the 80% rule which is 16 amps maximum load
(If you haven't picked up on it, I'm a complete novice; just bought my first house in April)
I'll go with 20 amps then
Code now tells us not to strap to the bottom of the floor joist. I guess that's in anticipation of finishing out an area further down the road. So if it were being inspected yes you would need to drill through the joist. The way you decide to do it is up to you it is an existing home with a mixture of both styles of wiring so it's kind of at a decision call on your part
Not sure that I'll end up finishing, but if its code it's worth the extra time to go ahead and do it
No problem that's what we're here for. You'll find a lot of this stuff is just common sense. You just need to exercise safety anytime you get into a live panel. If you're unsure of what you're doing you can always shut the main breaker off and use a flashlight or a headlight of some type to perform the work
^i did that twice already replacing all the outlets; I have a pretty healthy fear of getting zapped
Thanks again for your input, it's much appreciated 👌🏻
Yes I can be difficult because you have to kind of visualize how the circuit works a lot of times in order to work and safely. Anytime someone with limited experiences working on something they should be energized the circuit
I concur with greg 100%
@Izat - VA keep an eye out for broken tabs on outlets. They may be switched
As a rule of thumb on a 120v circuit a 100w is around 1a
And dimmer switches can only handle usually around 600w. So if you plan on dimming that area you may need to divide the load across two dimming switches
Good to know, luckily no dimmers here but I may do some on the main level eventually
Anyone ever make an alternator?
That is, convert physical energy into electrical?
It is not the easiest thing to do. You basically have a motor that is working backwards. You have to have quite a bit of copper windings inside the frame and you would have to spein it very quickly. If you had it attached to a bicycle or other of means it would not be so bad
Electric lady would not be that difficult to build the difficult part is when you have to do the spinning!
Seen them on sail boats. Was also thinking sewing table pedal.
Yes you have to get the ratios in the windings right and then have a set RPM to keep the voltage at a set level. I'm sure there are simple units I'm talking more along the lines of a consistent voltage output of 110v or higher
Any way to do it without copper? Practically I mean.
The two components of a motor or generator do not actually touch. It works off what is called induction. Copper or gold would give the best results. Some type of metal has to be used other metals do not work as well
Yeah is it basically a spinning core inside of coils?
Rotor and stator
Yes sir and giving what you're trying to do using steel or something of that nature just wouldn't work for the induction
Keep in mind when building this that it will always take more energy to make energy than the energy produced. Heat and friction are energy losses
This is the equation that prevents perpetual motion
Ugh im at a negro house giving an estimate
Literally a chimp out on tv..... and the smell....
Remove and replace a 225A single phase panel
@Lebens so you basically disconnected all the wires from the old panel, tracked them, and required them to the new panel?
How long does that take?
