In respect to this, what is an amp load box?
Essentially, a load box is a device that acts as an interface in which the energy generated by a tube amplifier can be expressed, without using a speaker cabinet. An amp head creates a lot of energy and power, and there needs to be a location for that energy to go. The device “loads†the amplifier.
One may also ask, can you use an attenuator as a load box? Attenuators. Attenuators passively reduce your amp's volume by absorbing some of the amp's output and passing the rest on to the speaker cabinet. Some attenuators also function as load boxes and feature a output that sends a line-level signal to a recording interface or another power amp for reamping.

The Electrical Load Box LOADS in charge to simulate the typical consumption of electronics' equipment. The Box is a 5U, 19'' modular rackable equipment that can house up to 50 resistors mechanically and thermally attached to two high efficiency heat-sinks, with integrated fans, for each box.
