Describe the bug
When using larger than 1 block wide accumulator multiblocks, and when using energy transport of other mods such as Create: New Age and Immersive Engineering, the top outputs will be degraded by arbitrary values from say 1/4 to 5/8 of the maximum output value in the configuration.

To Reproduce
Steps to reproduce the behavior:
Create an accumulator say 2x2 4 high (16 blocks total)
use some method to keep it fully charged such as a creative energy source from any mod
plug in some connectors and wiring from create new age or immersive engineering
use something to monitor the output and you will notice that even if the config is changed such that the accumulator's input and output rates are increased, they will not saturate the connectors and wiring, even when set to pull manually

a workaround ends up being splitting the accumulators into indivdual 1x1 towers as then the top output will actually saturate the connections and wiring

towers larger than 1x1 should saturate the output connections identical to 1x1 towers since otherwise it makes zero sense to use larger towers

Additional context

• Mod version: 1.2.1
• Forge version: 47.1.84
• Create version: 0.5.1.f

In addition to this, while the sides act as inputs exclusively and do not let any power out, the top outputs still let power to flow inwards, further complicating mod interaction since it creates a self-filling loop that further reduces throughput and increases energy losses, which again means that there has to be aditional measures to ensure energy only gets pulled out, including with Thermal Series flux ducts via flux limiter attachments.
For immsersive engineering this is not possible to do without adding additional capacitors or other storage blocks, even if you place just two connectors wired together, energy flows between them in both directions.
