"How much detail do you want? Kill-A-Watt can give simple loads, TED gives better details (but they can be flaky), there are multiple vendors with devices like the TEDs (The Energy Detective). If you choose a device that can provide volt,…"

"Yes, circuit level monitoring would be great but even monitoring feeds on a given panel could be useful. For example, a refrigerator turning on or off could easily be distinguished from a water heater turning on and off and if the refridgerator is…"

"You need circuit level monitoring for most of what you're talking about. You can monitor multiple loads over weeks or months and give them a web portal to look at cumulative usage for each load in their house. A lot of people want to know…"

"Definitely a different customer group as mine have always been looking for savings. And that is one of the reason why most would be unhappy. They would end up paying me and still have the high electric bills. And still believe…"

"It is my contention in most of these cases that there is nothing out of the ordinary going on but the clients insist that some kind of "power surge" seems to have fried some equipment of theirs, or there is some mysterious load sucking up…"

"Peter, if you create a database with all things electrical and a column for ratings and measured power consumption, you will be able to accumulate information over time that will make your job easier and more accurate. With that database or…"

"Wow, sorry, got busy for a couple of days there. I was looking for something that taps in at the first panel that would monitor power conditions as well as load over time so i could have an idea when there are voltage spikes and how large, if…"

"Peter, is your objective personal or an offering for customers? After the first run through what each appliance uses I have found it unnecessary to continue monitoring them. And, the initial use can in most cases be simply…"

"You can monitor 120v plug loads with a Kill-A-Watt, 240v loads with a TED, or do circuit level monitoring of entire electrical panels with systems from Powerhouse Dynamics, Brultech, and others. A good side to check out is Energy…"

Electrical system data loggers

A few years ago I was shopping for some sort of data logging electrical system monitor and came across some really interesting solid state units that could monitor supply and usage over time. They had a USB interface that would allow them to be plugged into a laptop to download the data for analysis. Does anybody here know of such an animal? I would think that this sort of tech would be becoming very affordable and available but just don't know where to look.

" Yes, that definitely does not include the trim but those vary very widely. Basic baffles are cheap but you should price a vapor proof trim for an H99. (i believe it was 4" cans we were discussing) I'm going…"

"It will definitely benefit you client to install the IC cans, but the price you are expecting to pay for them sounds a little high. I could swear I just got a quote for them last week at $12.95 per. Or are you talking retail price? Pricing aside,…"
