If possible, avoid placing high-current circuit breakers side-by-side. Not doing so causes concentrated heat collection

Install the GMT fuses so that the failure indicator flags are at the top.

•
Switch breakers to ON
•
Install fuses
Then test power and polarity at input of each equipment load or distribution unit fed by a circuit breaker or fuse.

LED lights up red. Also, check the
