Depending on the nameplate amps 30s may be too big.We just put l16-30s in all of our chargers and feed them with 30 amp breakers. It's more than enough to handle the load and allows the chargers to be moved around which is commonplace
What's the violation. I thought if you went over you were usually good. I've never seen a charger specify a max breaker size. Learn meBBQ said:Depending on the nameplate amps 30s may be too big. An NEC violtion but not one I would lose sleep over.
In general you cannot protect equipment at over 150% of the label.What's the violation. I thought if you went over you were usually good. I've never seen a charger specify a max breaker size. Learn me
But I may be wrong calling a charger an appliance.(E) Single Non–motor-Operated Appliance. If the branch circuit supplies a single non–motor-operated appli-ance, the rating of overcurrent protection shall comply with the following:
(1) Not exceed that marked on the appliance.
(2) Not exceed 20 amperes if the overcurrent protection rating is not marked and the appliance is rated 13.3 amperes or less; or
(3) Not exceed 150 percent of the appliance rated current if the overcurrent protection rating is not marked and the appliance is rated over 13.3 amperes. Where 150 per-cent of the appliance rating does not correspond to a standard overcurrent device ampere rating, the next higher standard rating shall be permitted.
Gross. Isnt it just as quick to throw up a piece of conduit?So Table 450.3(B) is not where I need to look?
Anyway, I have wired one so far. 208. I forgot the nameplate reading. It had internal fuses.
Currently there is an 80-85' run from a 480/277 in #3. It is on a 70 amp 3 pole breaker and stops at a JB. From there we have 4 existing battery chargers tapped from this.

3 of the current chargers nameplates show 11.6 amps and the 4th shows 9 amps.
I figure I could tap a 5th one from this that is rated at 13.6 amps.
Wait,, are you talking about the MC that is in the picture?Gross. Isnt it just as quick to throw up a piece of conduit?
That's what happens when you turn loose a low ball hack in a place he shouldn't beUltrafault said:Gross. Isnt it just as quick to throw up a piece of conduit?
Does not code required tap conductors to be in a raceway? I forget the article.That's what happens when you turn loose a low ball hack in a place he shouldn't be
How far the JB to the charger unit ?Does not code required tap conductors to be in a raceway? I forget the article.
Mine will be in a raceway.
Maybe you are correct unless I did misunderstood one part with the tap rules reguarding of 10 ou 25 feet rules which it will cross my mind a little.You're thinking of 240.21(B)(1)(3)
I will make it 10' or less.How far the JB to the charger unit ?
Merci.
That will work just fine with that part.,I will make it 10' or less.
Yes I was. Nothing wrong with the jb other than how crooked it is.Wait,, are you talking about the MC that is in the picture?
Then yes I agree.
