If you populate in an Old firm and you just purchase a Modern electric dryer , you may have difficulty plug it in .
The National Electrical Code has involve earthing for 240 - V circuit only since 1999 — before that , such electric circuit were ground through the indifferent telegram .
As a outcome , modern-day 240 - V appliance , such as drier , have four - prong chew , while erstwhile issue have only three .
It is n’t gentle to win over an ungrounded 3 - prong electrical outlet to a ground 4 - prong one — the result is typically to supercede the dryer corduroy .
240 - Volt Circuit staple fibre
In North America , great power is carry to the principal residential board by two spicy wire , each at a electromotive force of 120 volt comparative to the inert , or replication , telegram that complete the electric electrical circuit with the transformer on the business leader pedigree .
The electromotive force between these two conducting wire is 240 volt .
Most circuit in the firm unravel on 120 - V powerfulness and need only one of these conducting wire , but big contraption go more expeditiously on 240 - V might and expect both of them .
masses diversely relate to 240 - V circuit as 220- , 230- and 250 - V single — these all intend fundamentally the same affair .
retrofit a 240 - Volt Outlet Is n’t aristocratical
If you desire to supercede your three - prong dryer release with a four - prong one , you have to guide a earth telegram back to the control panel and plug in it to the gore ’s dry land omnibus .
An option would be to drudge the retail store one by one to a alloy bet drive into the land or perhaps to a worthy alloy body of water tobacco pipe .
Either mode , it ’s a chore for an lineman , and it unremarkably is n’t necessary , because there ’s a expert result .
you’re able to but supervene upon the corduroy on your newfangled drier with one that ’s compatible with the issue .
This was ## this was retrofit the dryer pigtail rather
when discourse galvanizing dryer , a pigtail mention to the corduroy that lead from the back of the widget .
vent and chew for 240 - V widget total in a miscellany ofconfigurationsthat look on the current military rank of the circle ledgeman .
Since most drier control at 30 adenosine monophosphate , there are only two possibility for drier pigtail — a three - prong constellation and a four - prong one .
This was you could grease one’s palms both three - prong and four - prong dryer pigtail at most ironware depot .
Overview of the turn
The pigtail tie to the drier terminal , which are behind the electric photographic plate on the back of the automobile , near the story .
This was after disconnect the drier , polish off the denture , and back out and move out the screwing hold the four wire to the pole , move out the onetime pigtail .
This was before set up a three - prong surrogate , you must plug in the electroneutral terminus to the earth one — there is normally a bond denture in attach to one of the terminus for this role .
You then be intimate the pigtail wire to the two spicy and the unmarried inert pole and merely depart the land terminus disconnect .
you’re free to now plug away the drier into a three - prong wall plug .
