Topic tags/keywords: 120 220 converter 10-30 l6-20

I currently have a Grizzly 0457 Bandsaw wired for 220 (L6-20) that I purchased from CL thinking I would just have a 220 outlet run.

I got a quote for running a 220 or a 20amp 120. Neither option was very feasible from a cost perspective (breaker box needs to be upgraded- couple thousand dollars worth).

At this point- I just want to sell the saw and start over but can’t power it on for anyone to prove it works (I was able to test before buying).

I thought I read here once that there is a gadget where you can connect 2×120 input lines (on different circuits) and it would spit out 220 @ 30amp. Does anyone know about this product?

Conversely I was thinking of trying to get an extension cord from the dryer (NEMA 10-30) but I don’t see anyone making such a cord. I would need at least 15’ to be able to get it to the saw.

Any help / ideas anyone might have would be greatly appreciated!

Thanks
DM

You can make your own extension cord that fits the saw outlet on one end and the dryer receptacle on the other. Home centers have everything you need and it will cost around $30 depending on what gauge wire you use.

You could run an ad on Craigslist offering to trade your
2 hp motor for a lesser amp one. I’m sure you’ll
get some interest as lots of guys have 1 or 1.5 hp
motors on contractor saws and would like a little
more power… and it does make a difference.

I just made a cord the other day- just pick the ends you need and assemble it yourself. Cost me $40 and 20 mins with all new parts.

I highly recommend AGAINST combining two circuits to get 220.. it’s potentially fatal since each legs circuit breaker will act independently of the other. One alternative is to re-wire the motor for 110V service. That motor will run on 110Vac, it just comes pre-wired for 220. Although, at 110V, you would need a 20A minimum circuit to handle it. As for the extension cord, as Doug said, make one.. it’s easy and everything you need can be found at your local Borg or hardware store.

Cheers,

you don’t have to have a new panel.

option 1: change a couple single breakers into doubles and that will make room for a 220 breaker.

option 2: add a sub – panel

option 3: just extend the dryer outlet into the shop. even if you have an electric dryer just don’t use them both at the same time

updating your panel is a great way, but very costly. The three options above are the most cost effective ways to go. this is just my opinion and they are listed in the order I would try. you may want to put the sub panel in the shop to make it easier to add things later. just my $.02

i believe this is what the OP was referring to:

i first came across this in shopnotes magazine. it is UL listed, CSA and OSHA listed. anyone who understands how 220v wiring works will realize that the way this item is configured is as safe as wiring a 2 pole breaker into a panel.
