I have been thinking (dangerous I know) Is there a way for an instrument (live ohmmeter / ammeter) or an electronic circuit to recognize the gauge (and surmise the amperage protection likely in place) ?
eg, measuring ohms from neutral to ground, (for 120 circuits) or doing a millisecond high-load test to see voltage drop? (I'm not an Electrician or an EE, but I have faith in their ingenuity :-) Where would i need this? For example, I got permission to charge from an inside outlet at a small building under construction. no idea at this time if it is 20a. (In this case, I could bring my circuit ID tool and look in the panel but don't need to at level 1 :-) (I got my EVSE cable yesterday ! :-) On Wed, Jan 20, 2016 at 3:28 AM, Bill Dube via EV <ev@lists.evdl.org> wrote: > Paul, > > There are a number of places in your home that are _required_ by the > national electrical code to have dedicated 20 amp circuits for the 120V > receptacles. > There are at a minimum five (5) 20 amp 120V receptacle circuits in a modern > house: > https://dbs.idaho.gov/programs/electrical/publications/2014_Homeowner_guide_brochure.pdf > Sometimes, in a low-cost tract house without a garage there are less, (and > in older homes there could be fewer) but typically there are quite a few > more.
