They are cooking you. If the beds are commercial units they can use
from 10 to about 20 KW. The time is about 5 to 15 minutes depending on
how much you want to tan.
I have not been in one either, just going by the specifications of them.
It does not mater if it is UV light or just heating units all of the
power will be converted to heat. Not sure how much the person will
carry out with them.
If the beds are that big he probably also needs to up the air
conditioner by about another ton.

Wire properly sized presents no risk, so IDK what the alleged problem
with wire heating is when the draw is within the 200A rating, there is
considerable margin. And
resistance is resistance, so a bad connection with resistance X is
going to create the same heat with 196A flowing through it on a 400A
service as it will on a 200A.

If you apply 240-Volt to the load and have 200 Amps current, you've got 48 KVA. If you apply 120-volt and have a 200 amps, you've got 24 KVA. If you connect 200 Amps load to each of 120-volt leg, you've got 48 KVA total.
That is just a guideline for some individual loads and a rule for
others. When you do the load calc for the whole service, you can
install based on 100% of the result if you are being cheap. The NEC is
not a design manual, it is just a minimum standard.

And oftentimes the pole transformer is not capable of 48KVA.
Most of them have their KVA rating painted right on the exterior of
(You may need binoculars to read it from the ground).
And dont forget that they often supply power to other homes and/or
buildings as well.

I was unable to install a 200 amp sewrvice in my home because the
transformer feed/undeground cable was lot large enough. I was limitted
to 125 amps.

That is certainly not true in the US. They will feed 3 houses from a
50 KVA unit and assume it will handle spikes above the 50 KVA. My
house os one of 3 on a 37 KVA unit. The guys told me, they will
replace it with a 50 when we burn it up.
These houses have 200a panels but they are fed with 2ga 1350 alloy
aluminum overhead service conductors. Voltage drop has not been a
problem here for me. I still get 124 or so

In reality there is never more than 200 amps of current flowing
in a 200A service. If it's a balanced load, the same 200A is flowing
through half the 120V loads, then on through the other half of the
120V loads. There is never more than 200A flowing in the service
conductors. You can support 400A worth of 120V loads, but it's
just 200A being counted twice.
