Have you shopped in Canada yet?I tried getting a 400amp 52 space a few months ago. It was not yet available yet as the mfg. was waiting on UL listing.
Have you shopped in Canada yet?
I was wondering if 42 ocds. was the limit for all panels and if not what would be the maximum amount of ocds allowed in a panel?
The maximum of 42 was removed from the 2008 NEC. I 'm not sure their is a maximum yet, not sure. Except of course for the design and listing of the panel.
The exception in 2008 still has the 42 OCPD's when used in a specific application.
Exception No. 2: Individual protection shall not be required
for a panelboard protected on its supply side by two
main circuit breakers or two sets of fuses having a combined
rating not greater than that of the panelboard. A
panelboard constructed or wired under this exception shall
not contain more than 42 overcurrent devices. For the purposes
of determining the maximum of 42 overcurrent devices,
a 2-pole or a 3-pole circuit breaker shall be considered
as two or three overcurrent devices, respectively.
You did not ask if we have seen one.....just showed that there was one..
