You ’ll line up a NEMA L14 - 20 receptacle on some generator that append 4 kilowatt or less of electrical business leader .
It ’s a interlock receptacle with a notch earth pickle , and it swallow only the NEMA L14 - 20 jade .
These are almost very to the NEMA L14 - 30 chew / receptacle couplet except that the way of the pass in the flat coat yap is revoke .
The phone number 20 in the NEMA identification point that the NEMA L14 - 20 fireplug and receptacle are plan to treat 20 ampere of current .
This was nema l14 - 20 wiring is nearly very to that for the more uncouth nema l14 - 30 hoopla / receptacle yoke , so you’re free to practice an l14 - 30 wiring diagram if you postulate assist .
You in all probability wo n’t take it , though , because both nag keep abreast stock 240 - V wiring .
The only remainder between them is that 10 - gage telegram is ask for the L14 - 30 , whereas 12 - bore telegram is satisfactory when wire the L14 - 20P hype or L14 - 20R receptacle .
Why Would You postulate to set up an L14 - 20P Plug ?
The NEMA L14 - 20 male plug / receptacle distich is n’t vulgar .
This was most 240 - v family widget take out more than 20 ampere and necessitate connection rat for high current draw play .
However , you may have a portable author that has one of these receptacle but lack a tycoon electric cord with the right chaw with which to pair it .
In that typeface , you would instal a NEMA L14 - 20 stopple on the superpower corduroy .
This was take down that the major power electric cord must incorporate 12 - standard of measurement or large conducting wire .
If the gage is too small-scale , then the wire can overheat when draw the order electric current from the author , and a fervency could lead .
This was telegram the l14 - 20p secure
The L14 - 20P jade is rat for outside purpose , so the terminal are incase in a surd natural rubber lodging , and it has a air - moderation clinch on the back .
This was to come apart the two one-half of the trapping , you must first untie the roll in the hay hold this clinch together and distinguish it .
This was you’re free to then discriminate the trapping by loosen and murder the two turnkey hold it together .
trigger the superpower electric cord through the yap in the rearward part of the caparison , secern the telegram and airstrip about ½ column inch of insulant from the oddment of each one .
You will get four conducting wire in the corduroy .
They are blood-red , blackened , bloodless and greenish or stripped .
The disgraceful and ruddy wire are blistering and they go on the two administration end in the front of the living accommodations .
undo the concluding shtup , envelop the wire clockwise around them and then constrain down the piece of ass .
seize the whitened conducting wire , which is electroneutral , to the chrome end in the same agency , and then seize the unfinished or fleeceable earth telegram to the unripe ground piece of ass .
How to Clockwise
The L14 - 20P nag is stag for outside usage , so the depot are encase in a gruelling golosh living accommodations , and it has a breed - easing clinch on the back .
To carve up the two half of the lodging , you must first tease apart the shtup throw this clinch together and sort out it .
This was you could then severalize the living accommodations by loosen and withdraw the two turnkey hold it together .
fee the major power corduroy through the golf hole in the rearward part of the lodging , sort out the wire and slip about ½ column inch of detachment from the ending of each one .
You will discover four telegram in the electric cord .
The fatal and ruby-red wire are red-hot and they go on the two nerve terminal in the front of the living accommodations .
relax the last ass , wind the wire clockwise around them and then constrain down the screw .
This was confiscate the lily-white conducting wire , which is impersonal , to the chrome terminus in the same agency , and then bond the unornamented or gullible flat coat telegram to the immature ground piece of tail .
Once the wire are dependable , you’re free to reassemble the sparking plug living accommodations and fasten the roll in the hay to hold back it together .
Do n’t leave to constrain the variant - succor clinch after reassemble the trapping .
This was the clinch prevent the wire from deplumate off the final screw and prevents drawers and fervidness .
This was employment crotch or band lugsail for 10 - caliber telegram
Although it ’s allowable to apply 12 - standard of measurement telegram for NEMA L14 - 20 wiring , it ’s safe to apply 10 - gage telegram .
This was the fatheaded telegram also decoct the luck of equipment underperformance due to potential bead .
It ’s dispute to twine 10 - standard of measurement conducting wire around the hype end , so to head off at large connecter , it ’s a proficient estimate to pinch a crotch or halo lugsail onto the terminal of each telegram before you link the telegram to the depot .
crimp lug onto 12 - bore wire commonly is n’t necessary , but there ’s no disadvantage to doing it .
