show us a make and model of a common residential or light commercial panel that has these restrictions. (and your local hardware store not stocking an uncommon breaker does not count as a restriction). One example of this 1/2 capacity thing not existing is Square D Homeline. They make a 200...

75a is only leaving you 15 amps after heaters. you need to do a load calc and size your feeder and subpanel accordingly

that would be 12ga wire, not 16. on fluorescent fixtures ignore the bulb wattage -you have to look at the current draw printed on the ballast.

im not talking about electrical noise (these days with switching power supplies in everything, noise is a given). im talking about the current spikes. Sure a couple CFLs on a circuit with other loads wont matter, but you cant go putting 40 or 50 CFLs on one circuit even if its only 1150 watts...

I wouldnt do it. Take a look at their design manual and follow it to the letter. You might get away with it now, and get hit with a 20K bill to relocate the line when they discover it later....

primary as in the high voltage side of a utility transformer? I'm sure your power company has design standards for the trench that would prevent you from putting anything on top of the electrical lines.

quick answer is no.

nope. cant undersize wire on lighting circuits.

cost, and no room for the necessary caps and inductors. remember with CFLs, power factor is only half of the issue. The other issue is the current spikes which a kill a watt isnt going to capture. Here's another way to put it: a normal 10w lamp would draw 10 watts all the time. A CFL will...

you need to size based on VA for the continuous load, but you still need to take into account the current spike unless you want your breakers rattling themselves to death. 20 bulbs probably wont be too bad but 60 would be an issue.

here is a good read on the subject http://www.cliftonlaboratories.com/compact_fl.htm "Although the average power consumed by the CFL is 21.2 watts, the peak current is 1.17 amperes. And, current is drawn only for 2.6 milliseconds for each half-cycle. At 60 Hz, a half-cycle is 8.33 ms, so the...

how i stated is the way its done over here. All the houses have the original 50 amp meter/breaker panels embedded in the stucco. Instead of tearing out the side of the house, new surface mounted panel is installed near the old service. Old service is turned into j box and old circuits are routed...

its not so much that you put in a new panel, its if you added a ton of load (i see BIG problems for the pocos as EVs are widely adpoted. They cant deal with everyone having a 10kw charger in their garage...

do some research on power factor. CFLs have a very poor power factor, usually .4 to .7 I put a 13W CFL on a meter that is able to capture short bursts of current draw and that 13w cfl needed 1.2 amps. Realize this is reactive power that isnt billed for, but its current that is flowing in the...

remember, even 19w CFLs draw their current in spikes of over an amp. Dont go thinking youre going to put 75 of them on one circuit.

whats a qualified electrician? Who pulled the permit, you or the electrician? If you pulled it, is it an owner builder or is the electrician listed on it? Does PG&E allow electricians to touch their drops? In so cal (overhead), for no downtime new service goes next to the old one and in one trip...

you are supposed to involve the power company when you do a service upgrade. How did you change your panels out without them shutting you off? Do you have a seperate meter base? Is the service overhead or underground? If overhead did you replace the riser, weatherhead, and service entrance...

those testers are not 100% definitive in their results as phantom voltage (for lack of a better term) can make the neon lamps glow. Sounds like you lost the neutral on the circuit. I would pull each receptacle out (with the circuit off) and i bet you find a backstabbed receptacle with a loose...

what would it cost to fix this up?

im not trying to make a profit off the vice, hardly worth my time. Just trying to get an idea of its value.
