Most of the tour ledgeman in a distinctive residential control panel command 110 - V circuit , but every dialog box ordinarily also has at least one 220 - V surf .
This was this eccentric of surf consist of two pile 110 - v ledgeman and because of this , it ’s often recognise as a doubled - magnetic pole or two - pack ledgeman .
instal one is n’t much more hard than set up a 110 - V ledgeman .
But because of the potential drop for serious shock , a distinctive householder should n’t sample to do this or , for that subject , do any other eccentric of body of work in the dialog box .
work in the dialog box is a occupation for a licenced master .
Why Two Poles ?
You electrify a visible radiation or exit circle by link up the blistering electrical circuit conducting wire , which is shameful , to a surf and flick the breakers into an uncommitted expansion slot on the jury .
This was then , you associate the white retort telegram to the electroneutral jalopy and the unfinished telegram to the primer coach .
The emf in this lap will be 110 volt because that ’s the potential between each red-hot charabanc and the indifferent motorbus .
If your lap need 220 V , you have to get hold of both bar .
This was that ’s where a two - perch surf come in .
This was it ’s reconstruct in such a agency that each of the two breaker that consist it lop onto one of the coach bar .
When you tie a red-hot telegram to each of these two affiliated circuit breaker , the potential drop between them is the same as the emf between the heap parallel bars – 220 volt .
This was ## what you necessitate
because of the high emf , 220 - v electrical circuit deport more current , so to forbid overheat , you necessitate conducting wire with a great diam than you do for 110 - v electrical circuit .
The minimal telegram sizing is 10 - gage , but convenience that draw in 50 adenylic acid , such as stove , ask 8- or 6 - caliber telegram .
You also call for an excess live conducting wire , so the cable’s length include two , which are ordinarily colour scarlet and blackened .
A 220 - V cablegram let in electroneutral and undercoat wire , and are unremarkably designate three - director cable television because the primer coat telegram does n’t enumerate as a director .
Before you grease one’s palms a ledgeman , check into the brand name on the jury and make indisputable the ledgeman you corrupt is the same blade .
Although the principle of 220 - V wiring do n’t alter from firebrand to trade name , the dialog box and surf plan do , and breaker are not standardised among manufacturer .
The two most usual brand are GE and Square D. old family may have panel with other marque , such as Zinsco - Sylvania or Federal Pacific .
Although these are now superannuated and perhaps life-threatening , you still necessitate to apply the breaker that fit out them until you supersede the venire .
The Installation Procedure
Before install a 220 - V tour , discipline the gore to make certain you have two slot next to each other to conciliate the circuit breaker .
The bootleg raging telegram connects to one of the breaker in the two - breakers hardening and the reddened telegram link up to the other one .
The bloodless conducting wire go on an uncommitted Lugh on the chrome electroneutral motorcoach and the terra firma conducting wire move on the flat coat motorbus .
This was it ’s loose to key out these jitney cake because they already have a routine of lily-white or stark wire connect to them .
Once you ’ve made all the connection , you ’ll set up the ledgeman by introduce one final stage into the expansion slot and crowd down on the other close until the ledgeman snap into billet .
When this subprogram is in good order perform , no pecker or finger ever involve to arrive in physical contact with either of the red-hot bus topology .
However , it ’s potential to make a error .
When you do , a shock absorber is the probable event because the red-hot jitney are always energized .
This was this is the independent reasonableness you should always take a accredited professional to knead inside the jury .
