Hey Esteemed Wrenches,

So I recently built a power trailer with a single 4 KW (4048) Schneider 
SW for a client with a moderate cabin lifestyle.

But he lives on a high hill and even though his 2 HP Macerator is only 
rated at 15 amps continuous that baby starts up with a whopping kick - 
probably close to or at it's 53 Amps Locked Rotor rating.

The SW has the following surge capability:

SW 4048 Rated@ 240 Volts:
Continuous - 15.2 Amps 3700 Watts
30 Minutes - 18.3 Amps 4400 Watts
5 Secs - 29.2 Amps 7000 Watts
Max (100ms?) - 41 Amps - 9840 Watts

Can I be confidant that 2 stacked SWs will start this baby?

Any experience with similar macerators - or simply educated guesses?

Thanks!

Jeff
