wiring new Waste King 8000 garbage disposal

justabovemaine

Hello, I am about to replace my old ISE Badger 5 garbage disposer with a Waste King 8000 1 HP unit. The old unit has a direct power connection (see attached), whereas my new unit has a grounded plug-in power cord (attached #2). If someone could please walk me through how to cut the current cord and convert so I can wire directly, I would appreciate the guidance. I promise to turn off power supply at the breaker before doing any work! Thanks so much in advance! I really want to learn how to do this myself, but am a newbie DIYer (just bought first house)....

How about a picture where the flexible conduit connects at the other end.

Why don't you take your old feed and mount a plug under the cabinet and plug the new one in.

A far better suggestion is to add an outlet to the old cable---For that you will need a steel 'handy box' an outlet and a steel cover and a BX to box conector and 2 screws to screw the box to the cabinet.

Tools---a pair of tin snips--and a screw drive--

Remove the steel cable from the old disposer---the wires will probably be to short to attach to the outlet when its in the box---so ---using your hands--break the steel cable open where you need by bending the cable in half---use the tin snips to cut off the extra cable --

inspect the wires for nicks--add the connector to the handy box---insert cable and tighten screws---

add your outlet---black to gold screw white to silver--break off the little tabs on the outlet on either side of the screws---

fasten box to back of the cabinet----screw in the outlet--add the cover--and you're done.




If you want to hook the steel cable into the disposer--look in the instructions---

open access cover---undo the wire nuts holding the cord --remove cord ---knock out the plug where the cord comes out---add a BX to box connector--install cable--make up the wires---Mike--

Thanks for all the feedback! I definitely like the suggestions of adding an outlet vs. hardwiring the new disposer unit. Attached is a pic of where the flex. conduit meets the wall. If I were to add the outlet here, I do not believe the power cord from the disposer would reach, so I think I'll just bring the conduit to the other side of the sink.

I may be back with more questions ;-) Thanks again!

Can you post a better picture of the plumbing in the cabinet. I am just curious if there is a trap on it, to keep sewer gasses from going out the sink.

Oh man, you should have used the WasteMaster 9000. Much better unit.

Oh man, don't diss my waste king 8000 ;-)

A Home Depot sales rep. talked me into buying a plastic box vs. steel because she didn't want to help explain how to ground the steel box... In my haste I went along and bought the plastic, but haven't installed. Should I return and get steel? If so, why? And how to ground? Thank you!

gregzoll

It is up to you, which to use. Just make sure that you connect the ground to the ground strap.

No she probably didn't know how to ground the metal box. If your bx has a ground wire in it, put it under the ground screw and it is grounded. If it is the old BX with a bonding strap, you fold back the bonding strap and tighten it under the connector and you are grounded. Wow that took me a minute to type, maybe two minutes if I was talking to you and trying to explain it to you.

Thanks! I'll return the plastic bx; don't think I can bring metal romex into a plastic bx anyway... ?
