hanging lamp controlled by two Lutron dimmers will not turn on

[klantz]

I have a hanging lamp in my kitchen that is controlled by two dimmers -- a MACL-153M and a companion MA-R. Everything was working fine until this morning when I returned home to find the lamp had come loose from its mounting bracket and was hanging solely courtesy of the wiring connections. All the wires seemed fine except the ground wire from the lamp, which had broken -- and, to my surprise, was attached to the neutral lead along with the neutral from the lamp. So, I reconnected that wire and reattached the lamp to the ceiling ... but no luck. Indeed, the MACL-153M is not registering any power (with its LEDs). What could have happened here and what can I do to fix it?

Thanks in advance.

No LEDs on the dimmer means there is no load on the dimmer or there is no power to the dimmer.

The neutral and ground must be separated. It sounds odd because the neutral and ground are connected at the service entrance but it does make a difference. Especially if you have arc-fault breakers.

Actually, turns out the MACL-153M was blown. Can anyone explain how the lamp's ground wire breaking -- when it was connected together with the lamp's neutral wire to the neutral lead -- would cause enough of a spike to blow the switch?
