Electrical Wiring in the Home/electrical


I have a 15 amp cord with gfci for a hot tub. is it ok to plug into a dedicated 20 amp outlet


The GFCI outlet is on the cord?     A lot of these cords are rated 15 /20 amp  but some are just one rating,

The GFCI generic has no over amperage built in,   so if the hot tub load is not to exceed 15 amps then the 20 amp behind the cord is 5 amps to high    because the GFCI is not a CURRENT type breaker,       follow?

Below is sorta backwards to what you are asking but you should keep everything the same all the way up and down the circuit,   now the 20 amp might have a little bigger wire feeding it but that is not a problem more a bonus but the 20 amp Breaker should be changed down to a 15, the GFCI is because of the hot tub,  water that kind of thing,    it measures potential fault current in a different way than a regular breaker that is looking to protect the wire of the pigtail     and it is again 5 amps to high,     for no more than the cost of a 15 amp breaker I would suggest changing it out,          

Table 210.21 (B)(3) in the National Electrical Code 2005 NFPA 72 shows:
If your Breaker is 15 Amps you may only use Devices (your GFI) rated not over 15 Amps.
If your Breaker is 20 Amps you may use 15 or 20 Amp Devices.
This is per the building codes and protect the minimum safety of installation. It is your house and you may do what you want, but if it burns down your insurance may have an issue paying you for it.

The code is written this way to protect you and others who may come into your home. If I come over and have something with a 20A rated cord the plug will only fit a 20A device. If I plug this into your plug on the wrong circuit, it will draw to much and 1. Trip the breaker 2. Burn out the breaker 3. if the breaker is already bad, overheat the wires in the wall causing a fire.

GFCI do not have an Over current Protection Device installed in them.
