If it was plugged into US 230v both Black and White would be hot. Mains feed here is 2 hots and Neutral hot to Neutral 115v hot to hot 230v (feed is from a center tapped transformer on the pole). WB5
Hi John and All, At least you do have a copy John. My strong suggestion is that all of us "who play radio" should have a copy close by. The readily available "Electrician's Guide to the 17th Edition
Tnx Scott and others for the info. Your system is more complicated because of the 117 v and 230v dual supply required. In the UK there is more conformity to wiring and the plugs are non reversible i

In Germany we all have a 3 phase 400 VAC system in our houses. Usually the kitchen oven and/or continuous flow water heaters are connected to a 3 phase system (the water heater is rated at 3x35 A, i.
LF I have a USA amplifier with 230v input. The mains wires are BLACK, WHITE, and GREEN The cct diagram shows White as the live wire with amplifier mains switch in this line, Black goes to the other e
Or a un insulated 10 inch probe if the there is a chance of an subsequent 'event' .... G Hi Scott I seem to remembr on what we call double insulated 2-wire units that you should not be able to touch
Hi Bob The normal mains supply to houses and offices is 230 volts ac at 60 amps. 50 Hz. For large industrial machines in factories they would normally have a 3 phase 440volt AC/50 Hz supply. Some pri
Agreed. Here in the US a current(!) copy of the NEC (National Electrical Code) is an essential night-stand accoutrement. And ditto on the isolated work-bench/radio supply. Add to that a mondo UPS and
440 3 Phase Not as standard . some engineering model makes have , but normally 240 1 ph Also depends on the age of the street , ie , this road only has 240 v single phase supply . while more modern l
Bob If you look at a Dentron 2500 amplifier on the cct diagram the 230v mains cable, WHITE wire goes to the ON/OFF switch on amplifier then primary of HT transformer which to me is HOT and BLACK wire
Hi All, For years as G3nyk will attest, my practice has been to run all mains operated test equipment via a single, large isolating tranny. The one I have also has a Faraday screen. One of the best s
Hi Mal, 'Is', but not always 'was' ;-) There used to be 'live chassis' radios and TVs with the single-pole mains on/off switch between the chassis and the neutral lead. Turn it off and the chassis wo
John The 2 pin plus earth non reversible seems a safer approach. A mixture of reversals is not good, especially in a shack with several electrical metal cased devices all with a common earth, floatin
Bob, (Warning: my comments are based on what I remember from the early 2000s. My copy of the UK wiring regulations is rather old. Can anyone provide more up-to-date information?) UK was 240 but is no

Hi Scott I seem to remembr on what we call double insulated 2-wire units that you should not be able to touch metal with a British Standard childs finger :-)) i.e via vents etc.
Hi Mal Something to keep in mind if the product was intentionally designed to be operated on 240VAC here in 120VAC land then it will NOT have a neutral or 'grounded conductor' in code speak. 240VAC i
Ah BTW, here all the power distribution up to 20 kV is below the ground, i.e. in cables, since the 60's. Some over-land wires are still existing in the country-side though. In Berlin, they even use s
