#10-3 cloth romex with #14 ground safe?


just got a washer and dryer and was wondering if the existing wire would suffice? the cloth romex seems to be in ok shape, it just has a #14 ground, is this ok? i will be using the a 14-30R receptacle.

also i am not sure if "cloth romex" is the right term, its early 60's romex type wire and it looks like it has that tar cloth type stuff as the jacket.

Personally, I would replace it. If you were to hook a megger up to it, it would come back that the insulation inside has most likely broken down. For current code, you need to have the wash machine on a dedicated 12/2, 20amp circuit. That means that it can not feed anything else, but a wash machine & gas dryer if you have one. You can though have a second or more circuits for convenience in that space, which those would fall under the SABC (Small Appliance Branch Circuit) catagory.

Megohmmeter is a special type of ohmmeter used to measure, or rather test, the insulation resistance of insulators. Insulators have electrical resistance in the range of millions of ohms compared to conductors which are measured in ohms. Insulators need testing for their insulation strength at the time of commissioning and as part of maintenance for electrical equipments and installations. For this purpose special ohmmeters called megohmmeters which can provide high voltages (typically in ranges from 500V to 2 kV) at specified current capacity are used. The minimum insulation tolerated are in the range of 1 to 10 mega-ohms, depending on the standards referred to.
