*Note: Total load not to exceed 2400W.

The power board surge protection has limited energy capacity. This means that it will protect so long as the joules sum is less than the rating of the surge protection.

It is possible for the surge protection to fail 'open' if it has too much energy input. This means that it works correctly until it absorbs too much energy and then fails leaving it as an open circuit. This is common for surge protection circuits to do in the case of over energisation.

The consequence of this is that the power board will look like it operates faultlessly, when in fact the surge protection is already faulted.
