Maximum power cord length for portable equipment

Maximum power cord length for portable equipment

Maximum power cord length for portable equipment

(OP)
Is there a maximum length for the cord connected to piece of equipment?

Specifically we have portable (wheels attached) infrared heater, 5000 watts, 240 volt, 1 phase, 3 wire which will be plug connected.  Is there a limit to the cord length?

RE: Maximum power cord length for portable equipment

in which country? In the USA it is usually limited to 6 feet.

RE: Maximum power cord length for portable equipment

(OP)
The application is the USA.  I checked the NEC 05 (the current adopted edition in MI) before posting and could not find any reference to cord length.  Would you please point me to the 6' reference.

RE: Maximum power cord length for portable equipment

I did not say it is a NEC requirement (except for certain home appliances, where it is even less than 6 feet).

This may be a UL /ETL requirement to meet the intent of NEC. I have not typically seen factory attached cords longer than 6 feet.

Also look up uses permitted and not permitted in NEC Article 400 which will restrict how long a flex cord you can have and the requirement of marking etc.
