gupster Posted August 26, 2006 Posted August 26, 2006 just come accross this that a guy ripped out of a thearter the lable has peeled back a bit but its marked 440v Nice!!
JB_ Posted August 26, 2006 Posted August 26, 2006 I doubt it's actually 440v, I thought there was some sort of requrement to put stickers like that on if there was 2 things on different phases within a certain distance of each other, panic over i'm sure.
Guest Posted August 26, 2006 Posted August 26, 2006 I doubt it's actually 440v, me too where the termials for the two extra phases than?
Paul P Posted August 26, 2006 Posted August 26, 2006 I doubt it's actually 440v, me too where the termials for the two extra phases than? There is a requirement that if more than 240 volts exist between equiment less than 2 meters apart it should be labled. The prefered wording is more than 240v exists between this and adjacent equipment, but some people just stick 415v stickers on everything. Incerdently you only get 440v on two phase suppiles.

Surely it is 400v on 2 phase?
Nova-Security Posted August 26, 2006 Posted August 26, 2006 Could have been 3 phase outlet by a dogey spark www.nova-security.co.uk www.nsiapproved.co.uk No PMs please unless i know you or you are using this board with your proper name.
Guest Posted August 27, 2006 Posted August 27, 2006 Could be anything really, could be the sparks had run out of 'DANGER 240V' stickers. I've got a 'DANGER 415V' sticker on my tool box, doesn't mean it's got 415V running through it.
Paul P Posted August 28, 2006 Posted August 28, 2006 Surely it is 400v on 2 phase? Nope defiantly 440v on two phase supplies like they use in the country side, 11,000 on two wires on over head poles and they fit a centre taped transformer to give two phases of 240 each which some how makes 440v across phases as they are 180 deg apart instead of 120dec on three phase supplies.

Lectrician Posted August 28, 2006 Posted August 28, 2006 Nope defiantly 440v on two phase supplies like they use in the country side, 11,000 on two wires on over head poles and they fit a centre taped transformer to give two phases of 240 each which some how makes 440v across phases as they are 180 deg apart instead of 120dec on three phase supplies. Nope - Three phase has 400v between any two phases (formally 415) Two phases would also have 400v, as it's simply two out of three phases in use. SPLIT PHASE would have 460v (formally 480) derived from two phases of a 11,000volt supply. The centre tap gives a 180deg wavefore - which is therefore an equal balance. 440v stickers go back to days gone by..... Email : martin@askthetrades.co.uk
james.wilson Posted August 28, 2006 Posted August 28, 2006 i reakon we should start making new stickers say caution 606v DC and see if they end up here, Im gonna stick one on the next 5a socket i see securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
