range receptacle : 3 prong versus 4 prong

[lardy1]

My house was built & inspected in 1998 and has a 3 prong electric range receptacle. I'm currently installing another kitchen and have duplicated the wiring in the service panel for the new breaker and wire using 6/3 with ground and a 50 amp breaker. Is there an advantage to one over the other? I'm assuming the additional is grounding the carcass but isn't the carcass grounded with a three prong? This is new construction so there is nothing to sacrifice. I want to be as safe as it should be which also makes me wonder about the existing one.

Can someone give this dummy a primer on range receptacles please? Thanks in advance.

Has been code since 1996 for 4 prong. 3 prong isn't an option.

Your house maybe snuck through on the pre 96 code if your town hadn't adopted the newest revision.

Just do it right-4 wire 6-3 with ground-makes a good impression on a "home inspector" and is just right!

Prior to the adoption of the 1996 NEC it was permitted to ground the frames of dryers, & cooking equipment to the neutral, now it is only permitted in existing installations, anytime there is a choice between 3-wire, & 4-wire, a 4-wire is the safest & best choice.

since this is new construction code requires 4-wire... good thing you ran 4-wire. now you just need to change the cord on the appliance to 4-wire. make sure you remove the bonding connection from the neutral terminal
