I read on wiki that AFCI breaker will need to see 75amp of arc fault current to trip. I assume they mean interrupt current The test current to trip the electronic sensor coil would be in the low range maybe mili amps perhaps?ok to Use a 1654b for that as it can deliver about 20amps of test...

Getting back to loop impedance testing I was wondering if any UK electricians Might share pros and cons of using 1654b tester . Seems like this is the latest model for particular co. I know there are similar meters out there? Would be interested to here about those Will the 1654b save records...

It all started with the wind turbines.. That' s a real disaster in many ways. There was no zoning in place when they started installing these massive turbines One town near here installed one near a residential neighborhood Huge problems developed for residents nearby not getting any sleep...

I went through an intensive six month training course on solar installation a few year ago. Passed the NABCEP exam all worth while given that fact that the training was provided at no cost. I was thinking it might open up new markets and wanted to be in on the ground floor The utility companies...

Glad everyone got off the Brittish Airways 777 in Las Vagas safely .Did someone say they earlier they were American Engines? Good job by the pilot and crew. Can't imagine Counting the minutes watching on TV

I should mention the requirement here in Massachusetts is 8,000 hr of practical on the job training and 600 hr of schooling to be eligable to sit for the licensed journeyman exam. Pass it then Wait another year of work experience and another 100 or 150 hrs to take master electrician exam. As I...

Sooner or later something on a larger scale will happen as a result of shoddy electrical work before the powers that be finally do something .We see theses tragedies happen all the time here in the U.S. particularly with people who loose there lives in house fires or are electrocuted. You would...

I read the Emma Shaw case and thought,It not until something's tragic happens that the enforcing athurothies step up to the place. There are way too many untrained and unlicensed people here doing electrical work everyday. The inspector alone can' t catch the violators . The state agencies does...

What's the electrical inspection process in the UK? Do you having inspectors that come on site and go over the job and your regs for violations or is it up to electrician? Here everything is about the code and so much confusion between Inspector interpretation of the rules from town to town and...

we are not really to stuck. It'sa split phase 120/240 coming in for residential mains with the neutral(grounded conductor)The electrical panel has a two pole mcb that feeds a two bus bars. We come off to feed 120v and 240v circuits Our general lighting and all appliance run on 120v And our...

Do the authorities pull up the paperwork with your loop impedance readings while performing fire investigations in the UK? I live in an area prone to hurricanes and flood damage. Do you retest wiring after floods?
