  • What amp breaker do I need to install for a Hobart 210 MVP? on the 230 side

    I have a 20amp in the garage as well. I need to know as I also want to buy a 25' extension cord. Some shops stated 30amp, 2 others stated 50 amp, one stated 40.

    Thank you

    There is the breaker, the wire to/from the receptacle, and then the receptacle itself. That's your basic circuit. Cords are a separate topic.

    I could be wrong but the way I understand it a 30 amp breaker will not protect a number 12 wire. I would think you would want a 20 amp breaker.
    I will have no problem being corrected if I am wrong.

    PHP Code:
    The breaker in your power box is not to protect the machine necessarilyIt is to protect the wiring in the walls
    Yes with some clarification if its possible from me.
    The breaker in this case has only 2 functions where on other general circuits it may have 3. Here it is basically an on/off switch and it doesn't "protect" the wire per sa for thermal, overload like a 20 A general where multiple devices may cause thermal but its for short circuit protection up to the switch on a 210 class machine.
    Thermal is regulated with the applied load. Same way an Edison base limits a fixture, you can plug a lamp with 16 cord to 20A circuit with no additional fuse.

    In the end, would it make it simpler to get rid of the 14 min wire size?

    My steamer or really pressure washer is built similar to a Stickmate except for a thermal on the burner fan motor where it has no thermal beyond the circuits it designed to be plugged in to. All the internal wire sizing is adequate for short circuit protection up to the listed plug came on it.
    Power strips for 120v are designed similar, have a cord with multiple outlets you must add a breaker if the wire is smaller than a 12

    I really don't feel like thinking it thru but somewhere on some machines allowed 14 for current conductors but called for a 12 ground, this not going to happen with a cord but some Hmm moments rather than answers in particular. 150A at 30%, even though it may draw more the duty is less, the 14 still meets the demands of the unit. Now since 14 will run it the thing comes with a 12, for a couple reasons. Not sure what the cost difference would be but they can use one cord across the Hobart line I believe. What does the IM230 use? Stickmate uses it.

    But they kept it specifically so this 210 class could be used on 50A welder circuits. So from an operators point of view the plug and there is a difference in end and cord rating here allows it to be used as a guide to the ocpd,,, not to be used to size the wire.
    Follow electrical service guide for
    230 VAC in Section 5-8. Do not use
    plug rating to size branch circuit
    protection.

    There is some thermal protection after the switch. If you use the minimum wire ,,, which no one thinks is a good idea you need to limit the breaker to 30, if you use 12 or better can breaker up to 50.

    I do have a question though.

    210 will draw 30 amps

    The 24 amp figure stated in another post is at the 150amp/30% output rating which is probably at tap 5 or between tap 5 and tap 6 of 7 taps. I do not fully understand the symbols on the voltage sticker on back but do think it says 30 or 31 amps input max. Why not just wire in a plug or 2 plugs with 6g or 8g wire and a 50 amp breaker? The on/off switch on the Hobart is also a breaker. The breaker in your power box is not to protect the machine necessarily. It is to protect the wiring in the walls.

    Dale, good deal on the 210 on June 6th at Tractor Supply In NJ.

    Believe manual states 210MVP only draws 24 amps on 230v so any 30,40 or 50 amp (dual) breaker should be sufficient....

    Manual also states minimum 14 gauge extension cord not to exceeded 53 feet.....

    Operating on 120volt will have different set of parameters and wire gauges....

    Look at page 17 here......

    Looking seriously at 210 MVP for acquisition... So any comments will be considered also....

    There are three or four pages in your manual that supply all the information you need on this subject.

    Buy a 25' 8-3. They are all over Amazon, eBay and online welding dealers. Breaker depends on wiring size. I run all my 220 machines on a 50 amp breaker and 6-3 Romex.

    I installed the 50A with 6/3

    I felt that the overage may be needed t times and prefer to have it higher and not need it. Thanks.

    I use a 40 amp breaker for my 230 volt plug in .I got a 242 volt reading for it .what wire will you be using to power the circuit ?
