13 kw portable generator inlet

[Stevenfyeager]

13 Kw portable generator needs a 60 amp inlet. 50 amp seems to be the highest amperage I'm finding. Any leads on where I can buy one ? Thank you. I just found out the cord is a 50 amp cord. Generator has 10,500 watts with 13,000 watts surge. But I wanted to cover the 13 Kw, which is more than 50 amps.

If the generator has a 50A receptacle, it’s going to be fused at 50A.

The generator should also have 120v 20A receptacles thus the additional power capacity. It likely has at least one N14-30L receptacle if not two.

My dad has a portable generator for his house with a 50A receptacle, and I built a cord with a 14-50 male end , a 50A CS female cord cap, and put a 50A CS inlet on the house.

Just how long does the 13kW surge capacity last?

Ive got a 15kw starting and 12 or 13kw running and biggest recep it has is a 50ampere.

"Surge" is just a lie. Consider it a 10.5 kw generator. Use a standard 50 amp connector.

What size breaker is in the generator? I'm guessing not larger than 50 amp.

Think of the cable and receptacle as rated for steady state usage (not surge usage.) Just like your generator is rated for 10.5kW (240V@43.75A) steady state usage, your cable and receptacle are basically rated for 12kW (240@50A). Now, your generator may support 13kW (240V@54.2A) under surge conditions, but so will your cable and receptacle. That is only an 8-1/3% overcurrent, and only for a short period.

IOW, your 50A rated equipment is fine for your generator. As shown above, your cable and receptacle are rated higher than your generator. (50A vs 43.75A) You don't have to cable the system for surge requirements, you cable for steady state requirements. I mean, in a factory, you wire motors for their FLA (Full Load Amperage), even though you know the startup current can be up to 10x the FLA. The short term surges in current may cause the wire to heat up, but it won't OVER heat, unless it continues beyond surge time timeframes, and that's what breakers and fuses are there to protect against. (Just like in your generator.)

In summary, your 50A cable and receptacle are fine for your application.
